Spending 80 Percent of Time on Existing Holdings

Chris Mayer, author of 100 Baggers and The Investor's Odyssey, on what three years on a public company board taught him, how he uses AI as a junior analyst, and what he actually does when a position gets cut in half. Stick around after the goodbye, where we talk stocks unfiltered.

Chris Mayer was the very first guest on The World According to Boyar back in 2018. Eight years later he's back, and he brought a new book with him. Chris runs Woodlock House Family Capital, wrote 100 Baggers, one of my favorite investing books, and just published The Investor's Odyssey, which uses Homer's story of Odysseus tying himself to the mast as a way of thinking about how investors protect themselves from their own worst instincts.

This one covers a lot of ground. Chris explains why he now starts many positions at 2% and lets them earn their way to a full weighting, why he cut most financial media out of his life, and why he believes the return you get on a stock varies inversely with the thickness of the research file. We spend a good chunk of time on Constellation Software, and I asked him what he'd need to see to actually sell it. He of course gave a thoughtful answer.

Chris also talks candidly about his three years on the board of Teqnion, a Swedish public company: the gap between what the board knows and what outside investors think they know, why it gave him more respect for activists, and why he'd join the board of every company he owns if he could. And we compare notes on AI. He has a page-and-a-half prompt that does in 15 minutes what he says would take a junior analyst a couple of weeks.

After we said goodbye, the record button was still on and we kept talking stocks. With Chris's permission, that conversation is at the end of the episode. Names that come up include Pool Corp, Uber, Brown & Brown, Markel, W.R. Berkley, and Rollins.
