Blackjack and Card Counting: Boaz Weinstein's Perspective

Boaz Weinstein, a successful trader and former chess master, demonstrates his card counting skills at a blackjack table. He emphasizes that card counting, while not foolproof (60% chance of winning in a session), provides an edge by tracking the ratio of high to low cards remaining in the deck.

Key Points:

• Card Counting System: Assigns values to cards: +1 for 2-6, 0 for 7-9, and -1 for 10s, face cards, and aces.
• Raw Count vs. True Count: The raw count is the sum of these values. The true count is the raw count divided by the estimated number of decks remaining.
• Advantage: A true count higher than three indicates an advantage, meaning more high cards are likely to be dealt.
• Bet Sizing: Weinstein adjusts his bet size based on the true count, betting more when he has an advantage. He bets between $100 and $2500 a hand.
• Patience: Card counting requires patience, as it may take time to find a favorable situation.
• Emotional Control: Managing emotions is crucial, as losses are inevitable even with an edge.
• Example: Weinstein asks to see the burn card (the card underneath the top card) and is pleased to see a six of diamonds, which is the best card to see as it increases the count.
• Doubling Down: Weinstein doubles down on 11 against a dealer's 10, illustrating betting when having an advantage.

Quote: "It's a game of patience. I would say a lot of things are a game of patience. Even if people don't realize, you know, like investing you could say is a game of patience."

Closed-End Funds: Applying Blackjack Principles to Investing

Weinstein draws parallels between card counting in blackjack and investing in closed-end funds. He focuses on exploiting the discount between a fund's market price and its net asset value (NAV).

Key Points:

• Closed-End Funds: Packaged stocks or bonds listed on an exchange, trading like a single stock.
• Discount to NAV: A fund's market price may be lower than the combined value of its underlying assets (NAV).
• Edge: Buying at a discount provides an edge, similar to having a high count in blackjack.
• Uncertainty: While the edge is known in blackjack, there is uncertainty in closed-end funds, but the degree of undervaluation is quantifiable.
• Analogy: "The reason blackjack is very similar to what I'm doing in closed-end funds is what I love about closed-end funds is I know the counts... there's the discounts in closed-end funds."

Emotional Control and Risk Tolerance

Weinstein emphasizes the importance of emotional control and risk tolerance in both gambling and investing. He recounts a significant loss in 2006 and attributes his ability to cope to his background and experience with games.

Key Points:

• Luck vs. Skill: Luck plays a significant role in both gambling and investing, and it takes time to distinguish between the two.
• Emotional Regulation: Games and sports teach emotional regulation by normalizing losses.
• Perspective: Weinstein's family history (his mother's survival of the Warsaw ghetto) provides perspective on losses in the market.

Poker and Hedge Funds: Liv Boeree and Galen Hall's Insights

Liv Boeree, a former astrophysicist and professional poker player, and Galen Hall, a former poker pro and hedge fund manager, discuss the similarities between poker and running a hedge fund.

Key Points:

• Where Does the Money Come From?: Both poker players and hedge fund managers must identify the source of their profits. In hedge funds, this involves identifying market participants acting non-economically.
• Pattern Recognition: Poker players look for tells and emotional cues, while hedge fund managers analyze the behavior of other market participants (e.g., institutions forced to sell, index funds with mechanical rules).
• Game Theory Optimal (GTO): The rise of online poker led to the development of GTO, a mathematically perfect style of play based on vast amounts of data.
• Image and Projection: In both poker and markets, projecting a certain image can influence the behavior of others.
• Variance: Poker provides a visceral understanding of variance, which is crucial for managing the swings in a hedge fund.
• Gamification of Markets: The increasing gamification of markets, driven by apps like Robinhood, creates opportunities for hedge funds to exploit.
• Prediction Markets: Prediction markets can be valuable for sense-making in an era of informational breakdown.
• Statistical Literacy: Gambling, in moderation, can improve statistical literacy and decision-making under uncertainty.

Quote (Galen Hall): "Playing poker professionally is like speed running a visceral reaction in understanding at a deep level what variance feels like."

Conclusion

The video highlights the surprising connections between games of chance and the world of finance. Blackjack teaches the importance of patience, edge calculation, and bet sizing. Poker emphasizes psychology, risk management, and adaptability. Both domains require emotional control, resilience, and the ability to tolerate risk. The insights from successful gamblers and traders demonstrate that understanding probability, managing emotions, and embracing uncertainty are essential for success in both arenas.
