The Last Moat | Chris Mayer and Ian Cassel on the Stock Picking Edge AI Can’t Replicate
Excess Returns
· · 1 hr 16 min · Hosts: Bogumil Baranowski · Guests: Chris Mayer, Ian Cassel
Summary
Chris Mayer and Ian Cassel argue that AI may compress the informational edge in investing, but it does not eliminate the human edge created by presence, judgment, and patience. Cassel says microcap investing still rewards being in the room, on the call, or at the factory, because repeated contact with management builds pattern recognition and helps him spot when a thesis is cracking before the market does.
Mayer agrees that the real edge is often not analytical—everyone looks at free cash flow and margins—but behavioral: staying with a business longer than most people can. He says vertical market software should be more resilient to AI than the market has assumed, because these systems are mission-critical, deeply embedded, and increasingly using AI themselves.
Both investors emphasize that management quality matters, but not as a source of secret information. The more useful value is understanding how a business actually works, testing management’s claims against other operators in the industry, and identifying repeat winners, owner-operators, and transition situations where a new team with pedigree can re-rate a company. They also stress that being an investor is more than being an analyst; execution, position sizing, and especially selling losers are part of the craft.
Key takeaways
- Cassel says the edge in microcaps is often relational, not informational: repeated management access helps him detect when a thesis is breaking.
- Mayer argues vertical market software is less vulnerable to AI disruption because it is mission-critical, embedded in workflows, and already adopting the tools itself.
- Both guests warn that talking to management can help conviction, but it can also create bias if the investor gets charmed by the story.
- Cassel says many microcaps have short shelf lives; a strong idea can become a 3x to 5x winner and still fail to compound for a decade.
- Cassel cites Lee Freeman-Shor’s work to argue that stock picking skill is heavily about execution, not just finding ideas.

How the episode opens
I think maybe a lot of people sort of just threw software all all out together in a bucket and now we're entering a phase where people are going to start to sort more carefully through who the winners and who the losers are. Tom Brady you know what he was drafted in the sixth round in 2000 you know and then he sat on the bench for a year and then in 2001 Drew Bledo I think lost the first two games gets hurt. steps in in 2001, takes him to an 115 record and then wins a Super Bowl, you know, and after that Super Bowl is when Chris Mayer would buy that stock.
Yeah. — Kind of a proven leader — And then he'd go on to win five more Super Bowls and he would have caged it at 25%. You know, where I'm I'm trying to find Tom Brady, not in college, — High school, not in high school, no, like fifth grade football.
We all look at free cash flow, look at the margins, we try to get a handle on competition. Everybody does the same kind of thing. A lot of that is out there.
I think, you know, sometimes I think the edge I really have is just the ability to look out longer than most people and hold on longer.
