John Harris presents at Sohn 2025
TL;DR
- John Harris, managing partner at Ruane, Cunniff & Goldfarb — $15B managed across several strategies, with the oldest dating back almost 55 years — pitched no stock. Instead, he offered “the proverbial rod” for investing in all weather, noting that the room would do well if just more than half of the stocks pitched worked out.
- The core claim: “Investing mostly happens in the heart, not the head.” There are “a hundred times, probably a thousand times” as many smart people in markets as successful investors; research and homework are table stakes, while success depends on managing emotions through markets that are “capricious and humbling.”
- Partners and clients are central to surviving the game. Harris advised younger investors to look around their offices and either “go somewhere else or fix it.” Without great partners, succeeding requires getting “very lucky,” and “luck is not a particularly great strategy.” Staying in the game is easier when colleagues are also friends.
- The talk was a tribute to Harris’s partner and friend, Chase Sheridan, who died earlier this year after a long and courageous fight with cancer. Harris described Sheridan as the model partner who told him he was “a complete and total idiot in the nicest and most respectful way,” then helped him get back in the game. Harris credits a healthy portion of his investing success to Sheridan’s friendship and support.
- In a green-room discussion about a partner who is losing money, Harris described the structural problem of concentrated, long-horizon investing: 15–20 stocks held for 10, 15, or even 20 years mean “the feedback loops are slow and the data set is sparse.” He stopped calling the firm a family because “in a family there’s no accountability,” landing on something more than a team and different from a family, with “no perfect answer.”
Digest · the substance, structured for research
1. No ticker on the slide — a rod, not a fish
- Harris, managing partner at Ruane, Cunniff & Goldfarb, said the firm manages $15 billion across several strategies, with its oldest dating back almost 55 years.
- His opening acknowledgment: with some of the world’s most talented investors pitching, “we are all going to be doing well if one more than half of the stocks that are pitched today actually work out.” Rather than “a fish that may or may not be so fresh,” he offered “the proverbial rod” for fishing “in all weather.”
2. The heart, not the head
- Harris’s comparison: there are “a hundred times, probably a thousand times, as many smart people in markets as there are successful investors.” Deep research and thoughtful analysis matter, but they are table stakes; the money is made by managing emotions through markets that are “capricious and humbling,” where much is outside an investor’s control.
- Who you do it with matters as much as how you do it. Without great partners and clients, he said, succeeding requires getting “very lucky,” and “luck is not a particularly great strategy.” His advice to younger investors: look around the office and, if the people there do not provide that support, “either go somewhere else or fix it.” Staying in the game is easier with colleagues who are also friends.
3. Chase Sheridan, the partner worth building around
- The talk was a tribute to Harris’s partner and friend, Chase Sheridan, who died earlier this year after a long and courageous fight with cancer. Harris called him a “beautiful bolt of lightning” who lit up the firm and made everyone better.
- The tribute’s sharpest image: Chase telling Harris he was “a complete and total idiot in the nicest and most respectful way,” then picking him up, wiping “the dirt off my jersey,” telling him to “stop whining, and go get back in the game.”
- Harris said, “whatever investing success I’ve had, I owe a healthy portion of it to him”—to Sheridan’s wisdom and insight, but “much more importantly” to his friendship and support on a journey “much more emotional than intellectual.”
4. More than a team, different than a family
- In a green-room discussion about a partner who is losing money, Harris described the structural challenge: the firm typically owns 15–20 stocks, often for 10, 15, or even 20 years, so “the feedback loops are slow and the data set is sparse.” Contribution can be something “you know when you see,” even when the P&L does not show it.
- Harris said he “studiously” stopped calling the firm a family because “in a family there’s no accountability. Your brother can kill someone and they’re still your brother.” The firm is “something more than a team” and “something different from a family,” but he has “never figured out what that is”; striking the balance is not easy, and “there is no perfect answer.”
