与 Verdad Capital 一起投资生物科技

TL;DR
  • Verdad 的核心判断是:系统化、量化的方法在生物科技领域同样有效,而生物科技恰恰是量化投资者过去完全放弃的板块。 Dan Rasmussen 的出发点是:生物科技约占 Russell 2000 的 25%,是市场上相关性最低的板块,但 Joel Greenblatt 的筛选模型却直接建议“排除整个生物科技行业”。Greg Obenshain 承认自己起初根本没把这项任务当回事——“我当时觉得,生物科技不可能做出量化策略”——直到结果让他彻底改观。
  • 最核心的信号是专业基金共识:把约 70 家生物科技持仓占比超过 50% 的基金视作一台“投票机”。 相对于持有该股的基金总数,被多家专业基金共同持有的股票表现强劲;被大量综合型基金持有、却没有任何专业基金持有的公司则“表现极差”。反直觉的是,专业基金的独有观点跑输共识观点——“当它是唯一一个这么想的人时,这个 alpha 观点很可能是错的”——因此跟随共识胜过跟随信念。
  • Verdad 的价值指标颠覆了传统价值投资:衡量价值的锚不是利润,而是支出——收入与经营现金流之间的差额——再与市值比较。 这个“简单得近乎愚钝的洞见”是:在市值相同的情况下,投入 5亿美元做临床试验的公司,平均而言比只投入1000万美元的公司更有价值。尽管构造粗糙,“价值指标的效果优于专业基金指标”,也是模型中最强的回报驱动因素之一。
  • 在做空端,生物科技 beta 天生糟糕——60%–70%的个股最终亏钱——但集中押注基本面的做空策略曾让专业基金遭受重创,迫使它们放弃做空,转而在 XBI 上维持约 105%多头、5%空头的仓位。 Rasmussen 的答案是量化风险管理:“相比于做空我最有信心的 7 只股票,我宁愿分别做空 70%的生物科技股票。”收益更多来自缓慢下跌而非股价暴跌,空头的价值在于降低波动损耗——“你完全可能在空头上亏一点钱,却因为做了空头而明显受益。”
  • 内部人买入具有预测力,但真正有用的信号主要来自前 CEO 以外的高管:“CEO 不管股票表现好不好,都会买入”,而 CFO 和其他 C-suite 高管的买入信号可以持续数月。 由于所有人都会卖出获授股票,卖出行为的信息量很低;Verdad 主要统计买入人数而不是金额,董事会买入也只有“轻微的预测力”。
  • 分类和动量都建立在临床试验数据之上:Verdad 将各公司的试验汇总成时间序列相似度指标,并在这些同类公司群中捕捉主题性动量。 Andrew Walker 质疑竞争对手获批理应对公司构成打击,Rasmussen 则以 Toyota/Ford 反驳:肥胖药物、mRNA 等宏观主题可能压过单一竞争事件,而且“生物科技的大多数波动都不是由具体事件驱动的”。
  • 更高层的策略是寻找遭受重创的板块,而生物科技专业投资者自身的悲观——“你们为什么要看生物科技?”——正是机会信号,类似“2015或2016年的石油”。 Rasmussen 如今的烦恼是,自己的逆向判断已经变成共识:“私募股权处于泡沫中,离它远点”如今登上头版;日本也已成为表现最好的市场之一,公司正努力更新自己的投资篮子,甚至半开玩笑地盯上了大幅折价的私人信贷 BDC。
摘要 · 为研究而整理的核心内容

1. 生物科技占小盘股 25%、与市场不相关,也不符合传统筛选条件——这正是 Verdad 进攻它的理由

  • Rasmussen 的切入点是:作为价值投资者,生物科技“完全不符合筛选条件……它们全都在亏钱。所以你会想,我是不是该直接放弃整个板块?但它占 Russell 2000 的 25%,那我到底该怎么办?”Walker 补充说,Greenblatt 的 magic formula 以及“大量量化基金”都会直接排除这一板块,而这恰恰构成了机会。
  • 投资组合层面的逻辑是:生物科技“是相关性最低的板块,真的很奇怪”——它提供了一个规模庞大、几乎没有系统性暴露的非相关收益来源。Rasmussen 让团队的债券专家接手这项持续一年的研究,起因只是一个玩笑:“生物科技股票大概就像债券吧。”两者都拥有大量现金。
  • Obenshain 的认知转变值得保留:“你没法真正使用财务报表……一开始我基本忽略了它,因为我觉得不可能在生物科技里建立量化策略。”真正的突破在于“按生物科技自身的规律来理解它——只使用在生物科技领域确实有意义的因子”。

2. 专业基金共识是一台投票机——独行者式的高确信度反而是负面信号

  • 定义刻意保持简单:专业基金是指投资组合中超过 50%配置于生物科技的基金,目前约有 70 家,不按历史业绩加权;ARKG 也只是“一条数据、一次投票”。Pfizer 这类战略性制药持有者也可能被列入专业基金名单,不过战略持股数据“更混乱”,仍在研究流程中。Walker 总结这一简化假设:有人把钱交给这些基金管理,因此它们大概确实了解这个行业。
  • 真正关键的不是专业基金的绝对数量,而是专业基金数量相对于所有持有该股基金数量的比例。Obenshain 称其中最有意思的发现是:“被很多基金持有、却没有任何专业基金持有的公司,表现极差。”这个指标最终起到了质量筛选器的作用。
  • 面对“为什么不直接跟着专业基金投资”的问题,Rasmussen 的答案是:当专业基金持有独有观点时,表现反而没那么好。“共识才是信号……你不希望生物科技基金经理拥有独立观点。当他是唯一一个这么想的人时,这个 alpha 观点很可能是错的。”Walker 的解读是:他们可能找到了唯一一个真正适合最佳创意型基金的行业。

3. 信号并不是预测事件,而是识别表现更稳健的股票,以及缓慢变化的 13F 持仓

  • 对于这一信号究竟来自临床试验成功还是并购,Obenshain 坦率地回答:“我没法直接回答你。”不过,高持股公司“往往会被收购”,而在这个行业里,并购“基本上就是成功的衡量标准”。但可供事件研究的样本太少;真正可交易的事实是,专业基金持有的股票“表现更好——相对于波动率的回报更高”,非常适合持续再平衡的风险模型。
  • 对于 13F 滞后带来的换手风险,Obenshain 的反驳是:一家规模 10亿美元的基金在小盘生物科技股票上投入5000万美元,持仓会“完全没有流动性……你被套住了”。共识仓位不可能快速移动——“10家不同的生物科技基金同时卖出一家小盘股的概率很低,但一旦发生,股价肯定会被砸穿。”
  • Walker 提出结构性反对意见:专业基金可能通过 PIPE 和低价认股权证获得更优条款,而实益持股申报有时会披露普通持股数据中看不出的仓位。Verdad 对此坦率回应:“我们正在研究。我还没有答案,但会解决。”听众提出的问题会直接进入 Verdad 的研究流程。

4. 做空生物科技:在基本面基金遭遇灭顶之灾的地方,进行极致分散

  • 前提是“生物科技 beta 很差”——这是长期亏损个股占比最高的板块,可能有 60%或70%的股票都是“科学项目”,只有少数彩票式赢家。因此做空必须成为策略组成部分,但专业基金基本已经放弃,转而维持“105%多头、5%空头,而且这 5%空头是在 XBI 上”的仓位,因为集中、高确信度的空头曾被宣传性拉升“彻底摧毁”。
  • Rasmussen 的解决方案纯粹是量化:根据市值、流动性、空头持仓和借券成本决定仓位。“相比于做空我最有信心的 7 只股票,我宁愿分别做空大约 70%的生物科技股票。”空头持仓因子在每个行业都有效——空头持仓和借券成本极高的股票“表现就是很差”——但最好的空头往往借券成本也最高,足以抵消预期收益,因此模型可能更偏好 50 个轻微看空、借券便宜的空头,而不是 10 个昂贵的高确信度空头。
  • 空头组合的回报“更多来自缓慢失血”,而不是药物试验失败导致的突然暴跌;它真正的作用是管理波动:“你完全可能长期在空头上亏一点钱,却因为做了空头而明显受益。”Walker 提到 SAVA 从 $8 一夜涨到 $180、涨幅 25倍且根本来不及平仓的尾部风险噩梦,Rasmussen 只用两个词回答:“高度分散。”

5. 内部人买入有效——但要降低 CEO 的权重,关注 CFO

  • 不对称性在于:卖出是噪音——“所有人基本都会卖出自己的股票”——非例行买入才是信号,但“CEO 不管股票表现好不好,都会买入”。Verdad 统计 CEO 以外的高管买入;“CFO 通常相当悲观,所以他们开始买入时,这是一个相当不错的信号。”董事会买入只有轻微的预测力。
  • Rasmussen 的发现是,内部人买入在被观察到之后“数月内仍然有效”,并不是日内交易信号。学术文献总在研究财报超预期前的买入,但“公司里的人不是这么想的……这是他们的生计。如果他们认为公司不错,就会因为认为公司不错而买入。”
  • Walker 提到,生物科技公司内部人经常面临很长的禁售窗口;他也见过 CFO 在临床数据公布后买入,包括在数据不利之后买入。讨论最终将这一信号视作持续且需要结合背景理解的指标,而非某个临床阶段专用的交易规则。

6. 重新定义价值:支出是价值锚,也是模型中最强的因子

  • Obenshain 对支出的定义是:“收入与经营现金流之间的差额……不管它叫研发、SG&A,还是打印机成本,都无所谓。”Rasmussen 对这个“简单得近乎愚钝的洞见”的解释是:假设所有生物科技支出都拥有相同的投资回报率,那么在市值相同的情况下,投入5亿美元做试验的公司理应比投入1000万美元的公司更有价值,尽管传统价值指标会把前者这个更大的亏损者排在更差的位置。即便试验失败,背后的团队也可能继续尝试重新利用这项研究。
  • Rasmussen 主动给出的结论是:“价值指标的效果优于专业基金指标……尽管构造极其简单,它仍是我们最强的回报指标之一。”原因在于,它衡量的是价值随时间的变化,而模型可以据此作出反应。
  • Walker 说,自己是在制药行业崩溃、公司股价跌破现金价值时开始感兴趣的;Rasmussen 则把这一切入点与 Verdad 偏好遭受重创板块的更广泛逻辑联系起来:“人们对某件事越悲观,它可能就越有意思。”他们访谈的专业基金经理都问:“你们为什么要看生物科技?”这“就像2015或2016年的石油”。Walker 担心支出指标会偏向昂贵的肿瘤和阿尔茨海默病试验,Verdad 的回答是“最终会大致相互抵消”,而且风险模型也不会让组合集中押注任何一个适应症。

7. 通过试验相似度给公司分类——动量捕捉的是主题,而非竞争关系

  • 分类难点在于,生物科技公司的临床阶段、靶点和核心试验都会随时间变化。因此 Verdad 汇总每家公司的临床试验,建立时间序列描述符,再计算它与其他所有公司的相似度——“我和那家公司有 54 的相似度,和另一家有 98 的相似度”——由此构建同类公司指数,用来衡量价值和动量。Rasmussen 称,一家同时拥有阿尔茨海默病3期项目和10个临床前肿瘤项目的公司是一个“非常难的问题”,这正是量化投资者不愿进攻生物科技的原因。
  • Walker 对动量提出质疑:竞争对手的膀胱癌药物获批,按理说应该打击你的公司,最多形成一个双寡头市场。Rasmussen 的反驳是,离散的竞争事件只占少数;“如果 Toyota 在上涨,而你是 Ford,你大概率也会上涨。”策略目标是捕捉主题资金流——“只要人们喜欢肥胖药物,我就想持有肥胖药物相关股票。”Walker 最终用 Pfizer 的 Metsera 竞购战举例认可这一点:竞购战推升了所有肥胖药物相关股票。
  • Obenshain 指出,生物科技从业者“太关注事件了。生物科技就是事件”,但“生物科技的大多数波动都不是由具体事件驱动的”。量化的优势在于捕捉底层驱动因素,而不是预测试验读数。

8. 用基准概率替代预测——而逆向判断变成共识本身也会制造烦恼

  • Rasmussen 在节目结尾引用价值因子研究:新闻会打击昂贵股票、提振便宜股票,因为“人们认为世界比实际更可预测”。如果市场给一项临床试验定价为 90%的成功概率,“那可能就不太聪明”;整个方法不是给单个读数计算胜率,而是构建仓位,“让最终发生的事件对你有利”。
  • 说到当下最惨淡的板块,Rasmussen 反而卡住了:“我们一直说私募股权处于泡沫中,离它远点。”现在“已经没人再因为这话骂我疯了,因为大家都同意我”。另一个判断日本也已成为表现最好的市场之一。“对价值投资者来说,连续两三年表现不错时,你就该开始担心了。”因此他半开玩笑地说,团队可能会“成为私人信贷 BDC 的超级多头”,因为这些资产正以大幅折价交易。
  • Walker 问到 KKR 2500万美元内部人买入时,话题转向最后一个方法细节:在内部人分析中,Verdad 主要依赖买入人数,而非买入金额——“我不想因为某个人恰好更有钱,就给他的买入更高权重。”针对 Walker 提到的 ServiceNow 案例,Rasmussen 追问:还有没有其他人在跟随 CEO 的买入?

You're about to listen to the yet another value podcast with your hosts me Andrew Walker. Today I have the team from Verdad Capital on uh Dan and Greg. We are going to talk about their paper they have on kind of value and fundamental quant investing in biotech. Look, I read the paper and I instantly reached out to them. I told I found it fascinating. You're going to hear how excited I am. I'm like a kid in a candy shop asking all these questions. Obviously, I do like more microlevel securities and they're talking macro quantitative like putting everything in, but I I found the paper fascinating. I think you're going to find the conversation fascinating. I learned a lot. Uh, I'm going to include a link to the paper in the show notes, of course, so you should go read the paper, but you're going to really enjoy this conversation. We're going to get there in one second, but first, a word from our sponsors. This podcast is sponsored by TRDA. Look, I've been me, you've heard me talking about TRDA for months on this podcast. There's a reason. It is a really, really good fit for you. If you like this podcast, TRDA is a interviews between two bysiders who are talking about stocks they like. Sometimes you get a bear and a bear. Sometimes you get a bull and a bull. Sometimes you get a bull and bear. Whatever it is, it is two byiders who are interested enough in a stock that they've done research and they want to go on and talk to someone else about the stock and you kind of be get to be a fly on the wall and listen and learn. I'll tell you what, I am recording this in the middle of February. It has been the SAS apocalypse and TRDA has been so so good. So many different companies are covered and you know in real time you're seeing people talk about hey is the AI risk real here? Hey I talked to a CIO of a company who you know they were looking into this and they don't need this anymore. Hey I talked to a CIO who said there is no chance in hell that we will get off of this product. So I I just think TRDA if you have not tried it you should try it. The most frequent feedback I get from people who try it through this podcast they come to me and say hey I really like it. I wish there was more of it. I wish there were more coverage. I love it. So look, if you haven't tried it, you should go to trtrada.com. That's tir trda t r a ta.com and go check it out. All right. Hello and welcome to the yet another value podcast.

I’m your host, Andrew Walker. With me today, I’m excited to have Dan Rasmussen and Greg Obenshain from Verdad Capital. Guys, how’s it going?

Dan Rasmussen

Good. Thanks for having us on, Andrew.

Andrew Walker

Thank you guys so much for coming on. As I told you before, we’re here to talk about the biotech paper you released, “Investing in Biotech.” I’ll include a link to the paper in the show notes. As soon as I read it, I was like, “I’ve got to have these guys on.” I was just so titillated by it, but we’ll start talking there in 1 second.

Just before we get started, the same disclaimer I start every podcast with: nothing on this podcast is investing advice. That’s always true, and maybe particularly true today because we’re just talking about the paper—no stocks in particular. There’s a full disclaimer at the end of the podcast and in the show notes if you want to get there.

You published the biotech paper, “Investing in Biotech.” There’s lots of stuff I want to dive into, but I’ll toss it over to either of you. What is the biotech paper? What does it say, what are the conclusions, and why did you start researching this?

Dan Rasmussen

Yeah, I think biotech is fascinating, especially as a value investor, because it’s a huge percentage of the small-cap universe but totally ineligible to us because, in some sense, they’re all money-losing. So you’re like, “Should I just write this entire sector off? But it’s 25% of the Russell 2000, so what the hell do I do?” I think that was really our starting point.

Andrew Walker

I’m sure you guys know Joel Greenblatt’s The Little Book That Beats the Market. He has you rank things on EV/EBIT on one side and ROC on the other. By the way, you just exclude the entire biotech sector from the entire screen. And he’s not the only one—tons of quants do it. So, yes, I just love that insight.

Dan Rasmussen

Yeah. I think, as an investor, you’re always looking for interesting sources of return that are uncorrelated to things that you already own, and biotech is the least correlated sector. It’s really weird.

For us, I sort of said, “Look, this is a huge percentage of the small-cap universe. It’s the least correlated sector, and no one else is really doing it in a systematic way, so we need to go figure it out.” And so I said, “Greg, bonds are boring. Do you want to stop doing bonds for a 1-year project and figure out biotech?” Not stop doing bonds because Greg can’t stop doing his day job, but biotech stocks are just like bonds, I guess.

Andrew Walker

Very. There’s a lot of cash in both of them. Greg, did you want to add anything to that?

Greg Obenshain

No. Biotech is strange because you can’t really use the financial statements. I will tell you that Dan asked me to do this, and at first I kind of ignored it because I thought there was no way you could build a quantitative strategy in biotech.

But as we started to look at it and think about how biotech works, we decided to meet biotech on its own terms and only use factors that actually made sense in the realm of biotech. We started to see results, and we started to see that it actually worked.

By the end, we really got some terrific results, and I think we’re firmly in the camp that a quantitative approach works in biotech. We’d be happy to dive into more detail on how we made it work.

Andrew Walker

Let’s do that. I want to start with the first—I think there are lots of things in here. I was really interested in a lot of it, but the one that jumped out to me, and I’m sure it’s going to jump out to people when they read it—and you basically lead with it—is that when you’re investing in biotech, you want to invest in things that sector specialists are heavily invested in, right?

If sector specialists own none of it, I think you say the returns from the things that sector specialists don’t own are basically zero over time. And if multiple sector specialists own it, then the returns are awesome, right?

I’d love to talk about how you guys started thinking about that, because I will just say, having talked to several sector specialists and looked at that, you guys found a quantitative insight into something that I think sector specialists kind of knew in their gut. They’d look at something, and when I talked to them, they’d be like, “Oh, no one owns that stock.” And they would kind of know it was because the science was freaky.

But how did you guys come up with that? And are there any other sectors that you can think of where the ownership itself serves as such a giant signal?

Greg Obenshain

Yeah, I mean, what we learned about that was from talking to sector specialists. One of the nice things about quants is that, at its core, it’s a fundamental exercise. You go out and talk to people about how the industry works and how to think about it, and we talked to people who said, “Hey, we follow what other people own.”

Then we said, “Well, we can do that. We can go out and get that data, download that data, and test it.” Like everything, it was just a thesis we went out and tested. We were surprised at how well it worked.

One of the interesting things that comes out of it is that I think a lot of people say, “Well, I only follow the best specialists.” That helps a lot. There are very successful specialists out there, but what we found is that if you treat specialists as a voting machine and just say, “Consensus matters, right? We want to see more than 1 specialist in there. We want to see several specialists if we can,” that really helps.

Then you need to think about things like, well, if the company is small and it’s unlikely to be owned by a lot of large funds anyway, what do you do? Well, then you say, “Let’s not just look at the number of specialists that own it. Let’s look at the number of specialists relative to all funds that own it,” right?

What you actually care about is the vote of confidence from specialists relative to how many other people are invested in it. And what you find, which is really fun, is that if you look at companies that are owned by a lot of funds but zero specialists, they do terribly.

The specialists are really just a great guide to the industry, and it really ends up being a quality metric. It ends up being an initial screen saying, “Hey, look here. This is going to be a good place to start.”

Andrew Walker

Are there any other sectors? I want to dive into the specialists in general, but are there any other sectors—and I know you guys do, and I’ve liked your stuff on Japan, and I know you guys do stuff worldwide—sectors, industries, or markets where specialists or insiders have such a heavy weighting to alpha?

Dan Rasmussen

We’re looking into that.

Greg Obenshain

Yeah, I think it seems promising, actually. But biotech would be the biggest outlier.

Andrew Walker

Makes sense. Let’s stick on the specialist conversation for a second. How do you guys define a specialist?

Greg Obenshain

You can define them in a lot of different ways. And we might change how we define specialists because we always go and improve our process, but biotech is always evolving.

But for right now, it’s pretty simple. We just say: Is more than 50% of your portfolio in biotech? What that allows us to do is build a robust set of comps to look at going back in time, and they’ll automatically drop in and out of the universe.

Andrew Walker

Okay.

Dan Rasmussen

Yeah.

Andrew Walker

Oh, please go ahead.

Dan Rasmussen

Yeah. What we’ve seen is that the number of specialist funds has actually increased pretty steadily over time. Right now, in our data set, there are about 70 specialist funds that we’re looking at.

Andrew Walker

You guys don’t weight them by saying, “This specialist fund has done 1,000% over the past 10 years, while these guys have done negative 10% alpha over the past 10 years.” If they’re a specialist fund, they’re in there, and they show up in the signal.

Greg Obenshain

Yep, correct.

Andrew Walker

One last question. There’s some level of quant, right? You have to make some sort of simplifying assumptions. Our simplifying assumption is that if they’ve been able to raise a certain amount of money to deploy only in biotech, they must have some biotech expertise—the people working there have to know something about biotech. I’ll come back to some other simplifying assumptions, but you’re saying that, for quant, that’s good enough, right?

We’re going to take 70 of them. If 5 of them are terrible, who cares? In aggregate, they’re specialists. Someone gave them money, and they must know something about the sector in order to be trading it.

It’s funny. Every now and then, I’ll have a guest whom someone didn’t like on the podcast, and they’ll say, “How could you let them on the podcast?” I’ll say, “Dude, it might not be your taste. It might not even be my taste, but these are professionals. People are paying them to invest. Who are you and I to say?” It sounds like you’re taking the same approach.

One more. I realize quant is, as you said, 70 big data points, but what about specialized active ETFs? I think the one that people might think of is the ARK Genomic Revolution ETF, which owns 10% of several biotechs. How would a specialized ETF in general—and I’m really thinking about ARKG in particular—be treated in your data set?

Greg Obenshain

They’d be 1 data point, 1 vote.

Andrew Walker

That’s completely okay. I wasn’t trying to hate; I was just curious. All right, so you guys discovered that funds and companies in biotech that are highly owned by specialists, particularly when the specialists are concentrated, tend to outperform over time.

I’d love to ask whether there’s any insight into what’s driving that performance. Is it that these firms are better at passing Phase 1, Phase 2, and Phase 3 trials? Is it that, when they’re successful, the drugs have better results, so the stocks pop higher? I can’t say “efficacious,” so I’m not going to say it. Is it that they’re better at getting sold? Is there better cost discipline? I know we’ll talk about cost versus value in a second, but is there anything behind it, or could it be all of the above?

Dan Rasmussen

It turns out that I don’t have a direct answer for you, but I do know that those are the companies that tend to get acquired.

Andrew Walker

Yeah.

Dan Rasmussen

That is largely the measure of success in this industry, right? Do you get acquired?

What’s interesting for us is that, as quants, we’re not going to make all our returns from events. We’re not going to model events. If you actually look at the number of events that happen, and think about just having a big sample size, there aren’t enough. We’re not doing event studies.

The way we’re making returns from companies that are highly owned by specialists is that they behave better. Their returns are higher relative to their volatility, and they tend to have higher returns on average. They behave really well in a model when you’re diversifying risk and trying to target companies that are going to increase your return and reduce your volatility.

That’s why they’re good for us. We think about it on a shorter time horizon than 4 years, right? We’re constantly rebalancing our portfolio to take advantage of the relative valuations and risks among companies. The specialist metric is just 1 metric that helps us do that.

We don’t necessarily know exactly why the specialists do better on a week-to-week basis, but they do.

Andrew Walker

One more on this. I definitely understand, and we’re going to talk about all the other metrics. I just thought the specialist metric was so unique from what I’ve seen.

It occurs to me that you’re getting most of your data—not all, because I’m sure you guys are updating for 13Fs and 13Ds, 13Gs, and stuff between quarters—but most of your data is probably coming from the 13F, right? Is this strategy a lot different from everything else you’ve run, or how do you think about it?

It seems to me like we’re talking in February—is it February 19?—and the 13Fs just got released. Does this result in a lot of turnover? The 13F gets filed, and you’re like, “Oh, 4 specialists dropped out of this thing,” or, “3 specialists came into this one.” Is it a little bit different, or are there ways to smooth that over?

Greg Obenshain

The thing about trading small-cap stocks is that, if you’re a $1 billion hedge fund and you’re putting $50 million into a biotech, you’re completely illiquid. You’re not getting in or out of that thing. You’re stuck.

Our view is that the 13Fs don’t change all that much. It’s not actually that fast-moving a signal. You’ll get some new buys or whatever, but they can’t move in or out very quickly. Because we’re looking at consensus—we’re looking at the things that a lot of people own—the chances that 10 different biotech funds all sell simultaneously in a small-cap stock are low. If that is happening, it’s going to tank the price.

Andrew Walker

You’re definitely right. RA Capital, RTW, and all these guys own 10% of these small caps. It’s got to be a success or failure. If they’re getting out, it’s probably because the pivotal trial failed, and they’re just like, “Wash my hands of it and be done with it.” There’s just not a lot of salvage value.

Anyway, there are some unique things about specialist funds, and I’m particularly thinking about PIPEs. Specialist funds can raise PIPEs, and they can do penny warrants. A lot of times, I know from trolling through these beneficial ownership filings, I’ll think, “Oh, there’s no specialist fund in here.” Then I’ll look and realize that 2 of the specialist funds own 10% or more of the company through penny warrants.

The other thing is, speaking of warrants, you’ll see a lot of times where a company will do a big raise and say, “Hey, we’re raising $100 million at $10 per share, and all the funds that are participating are getting warrants to buy stock at $15.” I could go on the market and buy the stock at $10 per share, but the specialist funds have definitely got a better deal than me because they’ve got the $15 warrants if things work out.

I’d love to ask how you’re adjusting for warrant ownership. I don’t think the second one matters for the way you guys are structured, but what about the penny-warrant ownership and those complications when it comes to ownership?

Dan Rasmussen

We’re working on it. One of the things we do is publish the paper, but we also have a research pipeline that we maintain. This is interesting about how we work in general: That was a question that came up the minute we published the paper. People will come back to us and say, “Hey, what are you doing about this issue?” We’ll put it in our pipeline and research it.

We’re well aware of it, and it’s something that we’re working on. The answer is that I don’t have an answer yet, but we will. Right now, we’re working on it.

Andrew Walker

Judging from the—people know that I’m really interested in busted biotech—but I tweeted out that I was having you guys on 2 hours ago, and judging from the amount of inbound I got, people are very interested in this paper. Maybe it’s just my circle, but I have 1 more question on sector specialists.

A lot of the big pharmaceutical companies will invest in smaller companies. Pfizer is 1 that I think about. Pfizer actually has to file a 13F. There are about 15 different companies where they partner on drugs and buy 5% to 10% of the equity. Do you guys consider them sector specialists, or is that a question for another day?

Greg Obenshain

No, actually, they do show up on the sector specialist list. One of the things we do is screen to make sure they get screened out if they only own a few biotechs. One of the things we do is screen out companies that are very small—sector specialists that are small—because sometimes those companies will show up as small even though they’re not.

They do show up, and we capture that. We’re also looking into whether having strategic ownership is helpful, but you can imagine that the data is a little messier, harder to obtain, and harder to validate. As a first pass, it’s much easier to get the specialist data, and as we go on, that’s something we’re digging into.

Andrew Walker

Makes total sense. Pfizer likes to take some equity in them, whereas a lot of other companies might just want to do a straight partnership on the drugs. You guys lead with the famous Pharmasset example, which, if I remember correctly, J&J had JV’d on the key asset there.

They did not own equity, and then Gilead buys them for a fortune. I bet J&J wished they had owned equity when Gilead came over the top and got them, but you have to think about all that. I completely hear you. I want to turn to some other questions on really interesting things in the paper, but I don't want to leave the sector specialist in case there are any burning insights or questions I should ask, or anything on the sector specialist we should discuss.

Dan Rasmussen

Yeah, I think the only thing that's sort of fun to note is that when we think about launching this strategy or managing it, one of the things people say is, “Well, why wouldn't I go with the specialists? If the specialists are doing all the work, why would I go with this strategy rather than the specialists?”

I thought one of our thoughts in response to that is to say, “Well, actually, when the specialists have unique ideas, they don't do as well,” right? You'd rather own the thing that everyone agrees on. The consensus is the signal. You don't want us to have independent opinions. You don't want your biotech manager to have independent opinions. Their alpha opinion—the one where they're the only guy who thinks it is—is probably wrong.

Andrew Walker

It's funny—you know, famously, every fund-of-funds or best-ideas fund that launches fails, and you guys might have found the one sector and the one strategy where it really starts to work. I want to go to shorting. You guys start talking about this especially at the end. It's a long-short strategy, and obviously, for quants, long-short strategies are kind of the nirvana: the shorts underperform the longs. That's how you really capture the alpha and everything.

But biotech is an interesting one to think about on the shorting side because you have these huge catalysts that can make it difficult to rebalance. I want to ask a lot of questions on the shorting side, but how do you guys think about the short side when you're facing the upside risk of, “Hey, if we're wrong?” It's not unheard of for something with zero specialists to get acquired for a huge premium or announce great results out of nowhere and the stock go up 10–20x. How do you guys think about just those dynamics on the short side?

Dan Rasmussen

Yeah, so I think the first thing to note is that biotech is really a fertile place for shorting because it's the sector where the largest percentage of individual stocks end up losing money over time. Biotech beta is bad, right? That's the value-investor instinct: “Wait, these companies don't make a profit. They don't even make revenue in many cases.” And you're like, “Yeah, a lot of them should fail, right? Because they're science projects.”

Very few of them are going to work and be lottery-ticket positives, but the majority of them, maybe 60–70% of them, are going to be money losers for you. So I think shorting has to be an important component of a biotech strategy.

Then there's the question of this being a sector that can be highly promotional. It can trade on news, right? We had a positive clinical-trial outcome, and the stock is up 40–50%. Even if the stock eventually fails, that's a pretty painful day for you. So I think our next observation is just around risk management on the short side.

I think what you've seen is that a lot of biotech specialist funds have abandoned shorting. They run 105% long and 5% short, and the 5% short is in XBI. Why are they doing that? Well, they've gotten burned on the shorts, is the truth. They apply the same approach to shorting as they apply to the long side, where they do deep research and say, “Well, I have high conviction that X is a fraud or something, or B is never going to work.” They put a 5% concentrated short position on it, and then they just get annihilated.

Maybe they get annihilated for a month; maybe they end up being right 6 months later. But it's just painful, and they have so many scars from it that they just abandon it altogether. Our view is that this is a place where quant is just really, really good, right? You can look at things like how big the market cap is, what the liquidity is, what the current short interest is, and what the borrow cost is.

You can say, “Hey, gee, you know what? I'd rather be short 70% of the biotech stocks individually than be short 7 of the highest-conviction ones,” right? So it's about position sizing and diversification of risk—all the things that quants are really good at and fundamental managers tend to be really bad at because they get caught up in ideas and double down on things when they go against them.

Or you're just really disciplined in rebalancing frequently and being pretty diversified. By and large, if you're short things that specialists don't own, that are pretty expensive on our value metric, and maybe have a little negative momentum, you're going to do fine on the short side.

Andrew Walker

Greg, did you want to add anything there? I had some follow-ups, but I want to make sure I gave you a chance if you had anything. You're on mute, but I think Greg's saying no, so I'm going to assume that's a no.

So, I jumped straight to shorting, right? Using this on the long side, another signal that you guys do use—you mentioned short interest—is basically one of the signals. I think you guys have found that if biotech stocks are in the most-shorted percentile, the returns on them are hugely negative, and basically every other quartile is kind of positive, if I remember the chart correctly.

I'd love to ask, just because you mentioned it—I've talked to these guys, and a lot of them are really hesitant to put shorts on—if these companies are ticking up in terms of short interest, who is the short interest, and what signal do you think you're picking up on when these shorts are high? Is it, “Hey, there's a lot of fraud risk,” or, “The science is so bad even journalists can figure it out”? Because it seems strange that it could get that high.

Dan Rasmussen

Yeah. Well, I think you have to remember that markets are very efficient, and this short-interest signal works across every sector. The stuff with really high borrow cost and really high short interest just does terribly. I think you can think about that as there being some stuff that everyone sort of knows is bad or dumb or fraudulent, right?

It's like, “They're going to cure cancer and they're out of a strip mall in Miami,” and you're like, “I don't know, probably not.”

Andrew Walker

You joke, but if you trade cancer for Alzheimer's, I have seen that in the past year.

Dan Rasmussen

There you go. There are these things that exist and are sort of obvious to everybody, but the manager is very promotional and makes the stock pop every 3 months with some crazy news item that's totally fraudulent.

But by and large, that signal works across all sectors because markets are efficient. It also creates the challenge that the best things to short have the highest borrow cost, and so you're basically neutralizing the borrow cost versus your expected return. Often, they're sort of neutralized.

So you actually need a really good model to layer in, “What's my expected return versus the borrow cost?” Again, this is a great problem for quants. It might say, “Oh, gee, it's better to be short 50 things we're kind of negative about that have low borrow costs rather than 10 things that we're really negative about that have really high borrow costs, which might be subject to a short squeeze if the sector pops the shorts.”

Andrew Walker

I'm just curious: Is most of the return on the shorts generated from, “Hey, these guys come out and the drug fails and the stock goes down 90%,” and the shorts were kind of right that the science was either very poor or fraudulent? Or is most of the returns from the shorts, again, as we've talked about, biotechs burning cash, and it's just, “Hey, these guys are kind of the path to nowhere, and they're just always burning their cash balance,” and that type of thing? Is it more slow bleed or just fast drops on the short side?

Dan Rasmussen

Yeah, it's more the slow bleed. To think about shorting in general and what it does for a portfolio, it really dampens the volatility of the portfolio. It limits your losses when the market goes down so that you can reinvest profitably. In quant speak, it's taking care of the volatility drag, and so it's limiting losses to allow you to invest and get the upside.

We don't really think about it as shorting for profit. You can actually lose a little bit of money on your shorts over time—the entire time—and be far better off for having shorted. You don't have to make money on your shorts for it to be a huge value addition to the portfolio when you're running a really disciplined, diversified quantitative portfolio.

Andrew Walker

And past month to 6 weeks aside, I mean, if you were running a large short book on tech stocks and you were like, “Hey, I've lost 5% per year on tech stocks for the past 20 years,” you'd be like, “You are the greatest short seller of all time. Put you in all the portfolios. My God, could we lever you up against the QQQ?”

Yeah, just one last thought. I thought it was so interesting because I've just got this one stuck in my head. Again, I know, as somebody who looks at the individual ones, I probably focus too much on the individual ones, but there was this company, SAVA, and I've seen several other ones like that, right?

They came out with a surprise announcement that the drug works, and the stock went from $8 to $180 overnight, right? So that's a 25x-plus move, and I just keep looking at them and thinking, “Man, if you had asked me to guess, I would have said 99.9% this fails.” When you get a 25x on a success...

I'm like, man, that is just a tough place. Even if you've got all the quant signals, a 25x move on a short is—oh my God—even if you started small, that is life-altering. And it's not like it went up 25x over 10 years, so I could cover on the way. It's like, no, you get hit and it's gone. So I don't know anything about that. Should we go to the next factor we're going to talk about?

Dan Rasmussen

Highly diversified. [laughter]

Andrew Walker

Another factor that you guys mentioned is company insiders. I thought this was interesting from a lot of angles. One of them is, again, I look at these individually, and the alignment of incentives in a lot of them looks so poor because the company insiders get lots of stock options and they're incentivized: invest in the R&D, invest in the R&D. It doesn't matter if it's a terrible EV, because if it pays off, you get a fortune, and if it doesn't pay off, you get zeroed anyway.

You guys just mentioned that the returns here are fantastic for company insiders. So I'd love to talk about that finding and what you see there.

Dan Rasmussen

Yeah, this was really fun to look into, and it's hard—it's really hard—to look at company insider transactions, get that data clean, and make it work. The very first thing I'd say about it is that, actually, in biotech and across the industry, sales don't tell you very much, right? They don't tell you who's bearish because everybody sells their stock. That's a standard thing: you're issued stock, and you sell it.

What's really interesting is the buys, right? When you do a non-routine buy, you only buy for 1 reason: you buy because you think your stock is going to do well. Every now and then, it turns out that the CEO always buys whether or not the stock does well, so they're not particularly a good signal.

But the management team—the rest of the management team, especially the CFO—I mean, CFOs are pretty bearish people. So when they start buying, it's a pretty decent signal. When combined with the other signals, it's a pretty decent signal, which is the reason you want your bond guy working on biotech, by the way. It's the same logic.

Andrew Walker

So, you're actually highly discounting CEO buys. It's really focused on the CFO and the rest of the C-suite. And what about boards of directors?

Dan Rasmussen

They actually are mildly predictive, not as much as the C-suite. So, yeah, we count executives excluding the CEO.

Andrew Walker

Okay. The other thing I think is interesting about the insider buys is that these guys—I haven't been on the inside of a biotech, but I would imagine they have much longer blackout periods than your normal company. From what I have seen, a lot of times you see insider buying after clinical data news, and often the stock is up 200% to 300%.

I've seen CFOs buying, and you guys say in the paper that insider signaling has a lot of signal here. I always think it's worth more when it's, like, hey, it's very rare for us to be able to buy. A lot of times, in the story I told, they're buying when the stock is way up, and sometimes after negative data they buy when the stock is down. I just think it's interesting that they've got such limited windows and that it's actually sending a signal. I don't know if you guys had anything else there, but I find it fascinating.

Dan Rasmussen

Yeah, we spent a lot of time looking at how rare the signal was relative to history, and there are ways to do that. There are great papers on that. What I'd say about what we found in the insider-buying signal is that, much like the specialist metric, it was actually a relatively long signal. It had power for months after you could observe it.

Andrew Walker

Interesting.

Dan Rasmussen

This isn't a day-trading signal at all. This is a signal about the power of the company. If people were bullish on what they're doing, they might know a long time before anybody else. It might be for reasons that are independent of earnings.

You go and read—and this is actually sort of an aside—you go and read the academic literature, and it's so focused around whether the insider bought right before earnings were good. I don't think that's how people in a company think at all, right? This is their livelihood. This is their money. If they think the company's good, they're buying it because they think the company's good. They're not buying it because they think the next earnings are going to beat Street expectations, about which they have no idea.

Andrew Walker

I could think of a few management teams who might, but in general I would agree with you.

Greg Obenshain

Interesting, but there's also a search factor, where you've got to try to find those people. But that's just too hard; it's too rare to play in biotech.

Andrew Walker

You do something interesting when you talk—I mean, you guys run a value shop, right? I'm a value investor. Most of the time, when you're talking about value stocks, you're talking about a company that trades cheaply to profits—gross profits, EBITDA, whatever you want to use.

You switch it here, right? As Dan said earlier, there are no profits here. There are often no revenues here. So how do you find value? You switch it from profits to spend. I want to ask how you guys came up with that and why you think spend is the right measure of value here. And could you define spend, if you don't mind? Yeah, Greg, you want to define it, and then I can talk through some—

Greg Obenshain

Yeah, it's actually really simple. It's the gap between revenue and cash flow from operations. So it is all the cash out the door. Whether it's called R&D, whether it's called SG&A, whether it's called—I don't know—printer costs, it doesn't matter. It's just how much money you're spending.

We don't try to bucket it in this metric, because spending can—there are a lot of valuable ways to spend, and you spend if you think you have something. So I'll let Dan go on from here.

Dan Rasmussen

Yeah. No, but I think I was going to say that, again, Andrew, it's sort of the dumb insight, right? It's not saying, hey, we know which specialists are really good and we're going to copy their portfolios. It's not saying, hey, we really know exactly the right type of spending or how to evaluate that.

But we're saying, hey, if you spent $500 million doing some clinical trials, you must have produced something. Maybe it was a complete waste of money, but surely, in the abstract, on average, a company that spent $500 million on clinical trials is probably worth more than a company that spent $10 million on clinical trials. And if they have the exact same market cap, presumably the one that spent more is worth more.

So it's just saying: take the spending as—you know, who knows what the ROI is—but just assume that there's a constant ROI for all biotech spending. You should value the ones that have spent more more, even though on a traditional value metric, obviously, the companies that lost more money are less valuable and worse.

You're sort of flipping that on its head and saying, no, these are science projects, and what they spent on that matters. Also, the fact that somebody gave them the money to spend on that matters, because those people are going to want to get some return on their investment. Maybe even if that trial that they spent all that money on fails, the people behind it are going to try to figure out a way to repurpose the research or something to make themselves whole.

Greg Obenshain

Yeah. And Andrew, sorry. I was going to say, you might be sitting here—and I think your listeners are probably thinking—well, that specialist metric sounds pretty good, but I don't know about this value metric; that sort of sounds really simple.

Well, guess what? When you run the data and figure out what's driving your return, the value metric works better than the specialist metric, because you need a way to measure how value is changing over time so you can react to it, and the value metric does that. So the value metric is actually one of the most powerful return metrics we have, despite the fact that it's an incredibly simple construction.

Andrew Walker

So if I'm thinking about it correctly, the value metric is just CFO. The more negative the CFO, the better, right? So it's basically assuming the R&D that's getting spent is getting spent on an at-worst-EV-neutral basis and, hopefully, an EV-positive basis. But that's kind of the way to think about it.

Greg Obenshain

That's the denominator, right? That's one side of it.

Dan Rasmussen

And then the numerator is the market cap. Obviously, a $1 billion company that spent $2 billion is weighted lower than a $500 million company that spent $2 billion.

Greg Obenshain

Yeah. So you think about that as an anchor of value. You need an anchor of value when you look at a company, and you need an anchor to compare to the market cap.

Andrew Walker

No, it's just interesting because, less so today than when you guys started writing and doing this—probably early last year, when the pharma sector was just imploding and everything was trading below cash—that's when I got interested. It sounds like we came at it from different angles, but in the same way.

You would hear people say, “Hey, that company's trading for $10, and they've got $20 of cash on their balance sheet.” And you'd hear people push back and say, “Yeah, but all that cash is going to R&D. They're going to burn it all.”

And you'd say, “Yes, but in the absence of more information, I kind of have to assume that it's getting spent, hopefully somewhat rationally. Are they spending so much that they're getting a negative 50% ROI on that investment? Because that's what it's calling for?”

But I'll pause there. I do have questions on it, but I'll pause there if you want to add anything to my story.

Dan Rasmussen

No, that's exactly right. I think part of that is—you got interested in the sector around the same time we did. We just love things that have been really bombed out and destroyed, because I think our general meta-view is that the more pessimistic people are about something, probably the more interesting the opportunity, right? You're looking for places where beliefs are correlated.

Rewind: when we first started doing this, as Greg said, one of the first things we did was find every specialist we knew and ask them a million dumb questions about how they invest, trying to discern what some of these signals are.

The amount of pessimism you heard from these folks was, “Why would you guys look at biotech? This is just a terrible sector.” And you're like, “Well, you've devoted your entire career to it.”

Then we'd be like, “Oh, maybe it'll be market-neutral,” and they'd be like, “Oh, thank God, right? Who would want long biotech beta?” At the time, the specialists were like oil in 2015 or 2016: people just got annihilated. That's always something that piques my interest in the sector.

Andrew Walker

So you guys go with, “The bigger the spend, the better”? I definitely get that you're adjusting for market cap, but that does seem like it would push you more toward an oncology trial or an Alzheimer's trial. Those are going to cost a lot more than a skin trial or an eczema trial or something.

Did you find that the signal works better in certain subsectors? Oncology has a much bigger spend and a much bigger target market versus some other areas. Or am I imagining too much there? Does it all come out in the wash in the quant data?

Dan Rasmussen

It kind of comes out in the wash. But when you talk about the research pipeline, that's the kind of thing that we know in other areas. Across sectors, when you're investing across sectors, using sector-level value can work. It can add something, but it's additive; it's not a replacement. So the answer is yes, we'll probably look into that at some point. We're constantly researching this stuff.

Andrew Walker

I'm interested because, when I first read the paper, my first thought was, “If they're going to spend, oh boy, they're going to be in a lot of Alzheimer's and oncology drugs.” Maybe what they found is that the past 10 years in oncology and Alzheimer's have been great, but going forward it's a very tough area.

Greg Obenshain

And, rather, the model also diversifies. Remember that even if the model said, “It thinks Alzheimer's is the only thing,” one of your steps at the end, when you're building a risk model, is that it won't put 100% of the portfolio in Alzheimer's.

So even if your value metric is wrong—if it's way too high in Alzheimer's—when you actually create a diversified portfolio, you'll even things out. You'll take the best of Alzheimer's, and then you'll take the best of everything else.

Andrew Walker

Judging by the returns on Alzheimer's, I don't know if there's a best publicly traded Alzheimer's company.

Speaking of sectors, you mentioned it: you guys also have something really interesting on momentum, where you talk about going trial by trial and classifying firms by what the trial is, then looking at momentum cross-sectionally among companies running the same trials. I want to make sure I understand that piece correctly. What was the methodology? What are you doing? Am I thinking about it correctly?

Greg Obenshain

Yeah, you are. This is the classification problem we're talking about: you need to classify these biotechs and group them. This value problem is exactly that, and we actually did test the value problem you're talking about; we just didn't put it in the model.

What you want to do is classify these things and group them together so you can look at how they move together from a risk perspective. Then you can say, “I want to build a metric within a certain class of companies.”

To do that in biotech, you can do it very simply: categorize them, call them something, and say, “This looks like that; this looks like this; this looks like that.”

But you get a time-series problem, because biotech can change over time. They go through phases, and there are different phases at different times. They might even change what they're targeting. Their lead trial might change; the one that's actually furthest along might change.

What you need to do to do that really well is go back and create a time series of descriptors of the company. The best way in biotech to create a descriptor of the company is to aggregate the clinical trials in which they're involved and aggregate them up to the company level.

You can say, “On average, they're doing these things.” Those clinical trials are great because they have so much data, so much detail, and so much classification data on what the companies are doing. The whole purpose is to build time-series classifications of companies so that we can categorize them and run metrics on them.

One quick thing: you mentioned the number. I do know of companies that will have 1 phase 3 drug, late-stage in Alzheimer's, and then 10 preclinical or phase 1 oncology drugs. The way you described it, it seems like that company would come out as an oncology company, but anyone who knew it would say, “Oh, no, that's an Alzheimer's company with a little bit of oncology—a call option sprinkled on top of it.” How do you adjust for that? Do you give bigger weightings to phase 3 trials versus phase 1? Can you adjust for the amount of spend on the trials? How do you think about that?

Dan Rasmussen

That's a really hard problem, and just as hard a problem for a fundamental analyst. This is why no one—this is why quant didn't want to attack biotech, right? All of these are really hard problems, but they're really interesting.

We discussed this in the paper, and there's a cool way that you can classify companies: you can say who they're similar to. Let's use this as a great example. You would say that this company is similar to a company with a phase 3 drug—I can't remember what your phase 3 drug was in—and it's similar to a lot of companies with phase 1 drugs.

Then you have to come up with some sort of algorithm and say how similar it is to each one of the companies in the universe. That number doesn't matter. It could be 1 through 376; we don't care. It's a scale.

You say, “I'm sort of 1-similar to that one. I'm 54-similar to that one. I'm 98-similar to the other one,” based on the phase, the indication, and where my headquarters are. I don't care.

Then you can take an average across that whole thing and say, “I'm most similar to that person.” But what you're not saying is, “I'm most similar to that person.” You're saying, “On average, I'm similar to these, and my average—the average company that looks like me—is this.”

Then I can go out and say, “How are those companies acting? How is my average acting? How's my index acting? What's my value relative to that index? What's my momentum relative to that index?” That's the way you can classify a company without really knowing which one is more important.

So we don't have that analyst sort of input, but we have a really sophisticated way to say, “Hey, we can look at who's similar.”

Andrew Walker

It strikes me that AI has to be both the most terrifying and the best thing for you guys. AI feels like it’s going to replace the humans who are doing quant, but at the same time, what you described is something you’d never do without AI running a lot of things in parallel with each other.

Greg Obenshain

And just as an aside, I taught myself to code from books, and I’m just really upset that everybody knows how to code now.

Andrew Walker

I’m kidding. I’ve been thinking about that a lot. Let me stick with momentum. We can have the discussion on AI and vibe coding if you want to, but let me stick with momentum.

If I’m remembering the paper right, in looking at my notes, you guys find positive momentum inside categories. If I’m going to say it bluntly, if Alzheimer’s drugs are doing well, all the Alzheimer’s companies start doing well. That’s my understanding; you can tell me if I’m understanding that correctly, but I’d love to know why you think momentum works.

Because when I look at these companies, what I often see is, “I’m going after bladder cancer, and you’re going after bladder cancer. You announce good bladder cancer results, and my stock goes down because, yes, maybe there’s a good signal that our targets work. But if your drug gets approved, I’m not going to have a monopoly. At best, it’s going to be a duopoly. At worst, it has all sorts of negative implications.”

I was surprised that they all worked together. I’d love to ask why, and what you’re seeing in that data.

Dan Rasmussen

Yeah, I think this is interesting because it’s actually a sort of market-wide phenomenon where similarity momentum, or pure momentum, works. In that discrete case, if a clinical trial gets approved for a competitor, that’s bad for you. But the vast majority of the time, if your competitors are—if you think of a car company, if Toyota is going up and you’re Ford, you’re probably going up. These things are influenced by big macro trends.

The thing you were trying to get at is being as precise as possible: What is really the exposure that’s driving this? Ideally, you want to capture almost the thematic thinking. People are really excited about obesity drugs right now, or they’re really off obesity drugs, and so I really want to capture that in my investing.

As long as people like obesity drugs, I want to own obesity, and as long as they don’t like it, I don’t want to own it. Basically, you incorporate that sort of thematic judgment into your investing.

I think that’s actually quite true of the way people trade. People get excited about certain topics or themes, and the market trades things that way, whether it’s for regions, sectors, industries, or peer firms. Often there’s some external driver for why that’s true. Maybe mRNA is having a terrible time and not getting anything approved, and so all our mRNA drugs sell off, or whatever it may be.

Andrew Walker

No, I think you’re definitely right. I was probably too narrow of an example because you mentioned obesity drugs. I know when Pfizer gets into a bidding war for Metsera, every other obesity-drug player goes up because they say, “Whoever loses that bidding war, they’ve already shown they want to buy, so they’ll probably come buy it.”

When I use bladder cancer as an example, bladder cancer drugs work a lot of the time. All the bladder cancer drugs work because they say, “Hey, at least the target has been proven. At least the mechanism of action has been proven.” So, a lot of them work.

Greg Obenshain

Yeah, Andrew. I was going to say one final thought on that. I think when I talk to people, you’ve asked so many questions that we’ve been asked before—and really good questions.

Andrew Walker

I was hoping for some unique questions, Greg.

Greg Obenshain

No, no, no. But I talk to people in biotech, and they’re so event-focused. Biotech is events. There’s a lot of movement in biotech stocks that is not event-specific. In fact, most of the movements in biotech are not event-specific.

When you actually do the quant research, you find that you’re not trying to target the events or predict the events. You’re trying to understand the core underlying drivers, how they drive stock prices over time, and how they move together.

So, it’s a very nonfundamental way of looking at it. You build the factors fundamentally, but there’s a very non-fundamental way to look at it, and it’s extremely powerful.

Dan Rasmussen

Yeah. I think there’s a famous paper—the title is something like “What Drives the Value Factor?” or “Surprising News About the Value Factor,” or something like that.

The finding is that when an event happens, the event’s impact on a stock is variable, dependent on the valuation coming in. If you’re a really expensive stock, news tends to have a negative impact on your share price. When you’re a really cheap stock, news tends to have a positive impact because, essentially, people think that the world is much more predictable than it is.

They price in— they get very optimistic or very pessimistic at the extremes, and then the news cycle just brings things back to the mean, in some sense. It’s just random dispersal.

If you say, “Hey, some of these events are just random. I don’t know, 30% of trials fail or whatever. I mean, that’s not the right number, but I’m not going to be that good at knowing whether it’s 25% or 35%,” all I should know is that if people think it’s priced like there’s a 90% chance, that’s probably not so smart. If it’s a 10% chance, maybe we should be long it.

I think that’s sort of the idea of quant. It pushes you toward this base-rate-driven approach: Let’s assume the market is sort of normal. Let’s assume that spend has a return. Let’s assume that all these smart people who study biotech know something about what they’re doing, and let’s assume that events are going to unfold unpredictably for everybody.

What really matters is whether you’re positioned in a way so that the events end up playing in your favor.

Andrew Walker

Yeah, but there’s no space that proves that more than biotech. I know companies that have announced that a drug failed and the stock goes up 100%. You ask why, and they say, “Well, people knew this drug was terrible, and they were worried that they were going to get just enough to continue spending and burn all their cash on it.”

Or a company announces that the drug works, and the stock is down 80%. Why? It was priced like it was going to be the best-in-class, literal cure for cancer, and it came out looking like a me-too cancer drug. There’s no place like biotech for that.

I’ll leave you with my favorite line in the paper. I told Greg before that my favorite line was: “Can a quantitative approach in a sector with idiosyncratic successes that are not reflected in the financials until years after the value is known work?” That was my favorite line in the paper.

I think you guys have done a great job explaining the whole paper and why it probably does work on this podcast. Unless you guys want to say anything else or have any last thoughts, I’m happy to wrap it up here.

Greg Obenshain

No, this is great. Well, thank you for having us on, Andrew. We’re really excited about this. It’s very cool. Biotech is such a weird sector. We did so much work creating new metrics and figuring out a new way to trade it, and we’re excited to see how it develops, to learn more about the sector, and to do more of this research.

Andrew Walker

I was just blown away by the paper. I thought it was so awesome and so creative to find so many unique signals. Again, some of the signals were things that, if you talked to sector specialists, they’d say, “This is what my gut says.” There were so many unique things, and I really enjoyed it. So, thank you guys.

Last question. Dan, I’ll put you on the spot. You mentioned that you love bombed-out sectors. That’s what Verdad’s focus is on. You had Japan. What’s the most bombed-out sector as you and I speak, February 18th?

Dan Rasmussen

Andrew, it’s a little bit frustrating for me right now because Howard Marks says you want to be contrarian and right—have a non-consensus view and be right. Right now, I think we’ve been sitting around and saying, “What has Verdad’s core argument been over the last few years?”

One, we’ve said private equity is in a bubble. Stay the fuck out of it, first and foremost.

Andrew Walker

KKR this morning would have something to say about that.

Dan Rasmussen

Yeah. Look at the front page of the newspapers now. People agree with us. I’m going to have to start—me saying that private equity sucks, and nobody yelling at me, “You’re crazy!” anymore because everybody agrees with me now. KKR bought $25 million of stock this morning, though, so you guys might have to throw them into the insider-purchase screen.

Maybe it’s still good for KKR, but I feel like that was one of our non-consensus bets that’s looking pretty smart. We’ve also been saying, “Hey, Japan’s a great place to invest,” and all of a sudden, over the last few years, Japan’s been probably the best-performing market out there. We’re having trouble refreshing our basket of new ideas.

For a value investor, you start to get worried when you have 2 or 3 good years in a row. You say, “Oh, gosh, maybe it’s overvalued now.” So, we’re refreshing. Maybe Greg and I will just start becoming huge bulls on private-credit BDCs or something. Yeah, they are trading for big discounts. So maybe that is the best.

Andrew Walker

Hey, can I ask one last question? I’m sorry to prolong it. On insider purchases, the KKR one brought it to mind, right? $25 million is a lot of money. I don’t know if it’s that much money to them. Do you guys adjust for the size of insider purchases, and maybe the size of the insider purchase versus compensation, when you do the adjustments?

Dan Rasmussen

In general, when we make metrics, we’ll do a count and a volume, right? So we’ll average them, or look at both of those. In the insider data, we mostly just relied on counts because we wanted the intention. I don’t want to credit somebody more because they just happened to have more money. So we just used counts in that analysis.

Andrew Walker

Again, this might be quant versus story, but with ServiceNow, the CEO says, “Hey, I’m canceling my 10b5-1 and I’m going to buy $3 million of stock over the next year through a 10b5-1.” You’re like, “Hey, that’s a nice signal, but you get paid $40 million per year and you’ve sold $100 million of stock over the past 3 years. Your stock is down 60%. Maybe you could add a zero to that.” That feels very much like, “Hey, guys, I’m here with you.” So, I don’t know.

Dan Rasmussen

Well, the question is, is anybody else following—

Andrew Walker

Right?

Dan Rasmussen

All the execs canceled, but yeah.

Andrew Walker

Yeah. And was that the CEO? Because the CEO was fine.

Dan Rasmussen

It was the CEO. All the other execs canceled their 10b5-1s, which I think is also interesting, but that’s just the one that came to mind where I was like, “Maybe we could add a zero to that or something.”

Andrew Walker

Guys, it was a great paper. There’s going to be a link in the show notes. I really appreciate you coming on, and hopefully we’ll have you guys again for the next interesting one.

Dan Rasmussen

Thanks, Andrew. This was a blast.
