Episode: "Even the Pros Are Wrong Half the Time. Here's What They Do Differently" (SB1820)

Date: March 25, 2026
Hosts: Joe Saul-Sehy & OG
Guests: Claire Flynn Levy (Essentia Analytics CEO) & Lee Freeman-Shore (Author, Former Fund Manager)

Episode Overview

This episode demystifies professional investing by highlighting research on top fund managers—the "Stock Market Maestros." Joe and OG are joined by Claire Flynn Levy and Lee Freeman-Shore, who reveal that even the world’s best investors are wrong almost as often as they are right and share what these pros do differently to outperform. The episode combines case studies, memorable metaphors, and actionable advice for both seasoned and everyday investors.

Key Discussion Points & Insights

1. Setting the Stage: Who Are the "Maestros"?

• Maestros vs. Wizards:

  • "Wizards to us are people that are more short term orientated, more trading... The 12 stock market maestros we feature are phenomenal investors... but they tend to take a longer term view. They're investors, not traders." – Lee, [10:11]
  • Maestros invest for the long-term and focus on public equities, whereas wizards are active traders.

• Maestro Selection:

  • The research is based on in-depth data from award-winning fund managers, narrowed from an initial 70+ down to a dozen based on objective performance analytics.

2. The Reality: Professionals Often Get It Wrong

• Even top fund managers only “hit” on their picks less than half the time.
  • "The chance of an idea making money is 49%. And these are the best investors in the world." – Lee, [15:20]
  • The crucial differentiator isn’t having more winners than losers, but maximizing winners and minimizing loser impact.
  • "It's how they behave when they are right and how they behave when they are wrong that makes all the difference." – Claire, [13:15]

3. Behavioral Archetypes: How Investors React

When Losing:

• The Rabbit: Does nothing, hoping for recovery. Dangerous if the loss deepens. Fired from Lee’s team.
• The Assassin: Cuts losing positions coldly after a set loss threshold (e.g., at -20% to -40%).
• The Hunter: Puts more money into a declining position if still convinced by their thesis—a move risky even for pros.

When Winning:

• The Raider: Sells quickly after a small profit (10–20%) and loses out on big returns.

• The Connoisseur: Lets winners run and compounds returns. Most top fund managers’ performance is due to a few huge winners.

  • "You want to be a connoisseur. Connoisseurs are people that—the Peter Lynch—you run your winners and you win big." – Lee, [23:35]

• Special Case - The Lumberjack: (John Barr) Plants many small positions and lets the biggest winners grow disproportionately—rare among pros.

4. The Power of Process Over Gut Feeling

• Data, Not Instinct:
  • "Their emphasis on these maestros. No gut decisions. 0.0 gut decisions. All data driven all the time." – Joe, [52:35]
• Investment Policy Statements (IPS):
  • All maestros documented and adhere to strict processes—sometimes involving formal checklists, screensavers, or corkboards for constant reminders.
    • "Having, using technology is key because you don't want to have to dig that thing out every time." – Claire, [35:44]
    • Example: Laminated rules on the desk (Stephen Annis), or corkboard reminders (John Lin).

5. Case Study—Josh Goldberg's Winning Approach [24:20 – 31:08]

• Waits for evidence, like earnings surprises, rather than predicting them.
• Uses clear entry/exit rules (e.g., never losing >1% of the fund on a position).
• Data informs his average holding period—about 15 months.

6. How to Know When to Sell

• Set objective criteria for reevaluating or exiting (e.g., down 20% triggers a review).
• Ask, “If I didn’t own this already, would I buy it today?”—helps cut emotional ties.

7. Portfolio Construction & Position Sizing

• Diversity in Position Management: Some maestros trim winners that grow too large (>4–6% of the portfolio); others (like John Barr) let big winners ride but start with tiny initial stakes.
• Regular rebalancing and incremental changes are common, rather than wholesale moves.

8. International Differences

• Market Nuances: Strategies may shift in different regions (e.g., China’s retail-dominated market incentivizes short-term gains).

9. Building and Improving the Machine

• "Why wouldn't I build a machine and operate the machine that will help me make better investment decisions in the future?" – Joe, [54:23]
• The best investors continuously refine their process and remain humble learners.

Notable Quotes & Memorable Moments

• "You have a less than a 50% chance that your idea is right... Most people innately believe that they're right more than 50% of the time." – Claire, [19:23]
• "If you've already got a plan of action as to if things go wrong here's the checklist... you should have all that set up before you even put a single penny in a name." – Lee, [35:12]
• "Looking in the mirror can be kind of mortifying sometimes. Not everybody is feeling brave enough to do that. But these guys have all gone there, had a good look, figured out what it is that they're not perfect at..." – Claire, [26:13]
• "If you strip out those two or three big winners, their returns profile…becomes very average or bad." – Lee, [23:35]
• "It's so easy to fall prey to the endowment effect...you can fall in love with a stock, with pretty much anything..." – Claire, [41:07]
• On humility and improvement: "They're all humble enough to look in the data mirror..." – Claire, [26:13]

Actionable Takeaways

1. Don’t Obsess Over Picking Winners:
   Even the world's best are barely right half the time. Focus on process, not perfection.
2. Cut Losses Quickly:
   Don’t hold onto losers; set firm rules or checklists for exits.
3. Let Winners Run (But Monitor Position Size):
   Avoid cashing out too soon—big returns may depend on just a few outliers.
4. Document Your Rules—Then Follow Them:
   Investment Policy Statements are only useful if regularly referenced and updated.
5. Beware of Overconfidence and Biases:
   Recognize your own fallibility and use data for honest self-reflection.
