Episode Summary
Executive Summary: In this podcast episode, host Patrick Boyle interviews Jack Schwager, author of the Market Wizards series, focusing on his latest book 'Unknown Market Wizards.' They discuss the flaws in the efficient market hypothesis, using examples like the NASDAQ bubble of the late 1990s and the Cuba closed-end fund anomaly. Schwager explains that while markets are not efficient, most people are better off investing in index funds. The conversation explores common traits of successful traders, including adaptability, emotional control, learning from failure, and the importance of not trading unnecessarily. Schwager emphasizes that trading requires hard work, a developed methodology, and proper risk management.
Main Topics: Efficient Market Hypothesis Critique (Priority: 5/5): Schwager argues the efficient market hypothesis is clearly wrong, citing extreme market moves like the NASDAQ's 600% rise and 85% crash in 18 months, and the CUBA closed-end fund anomaly where an 85% price move occurred based purely on the fund's name after normalizing relations with Cuba. Market Adaptability (Priority: 5/5): Successful traders must adapt to changing market conditions. Schwager discusses how both discretionary traders (like Peter Brandt) and systematic traders (like Marston Parker) evolve their approaches as markets change, with systems that once worked becoming consistently unprofitable. Emotional Control and Self-Improvement (Priority: 4/5): Trading exposes psychological flaws. Schwager highlights traders like Richard Barge who keep emotional scorecards tracking behaviors like 'sugar trades' (unplanned trades). Others use meditation and breath work to achieve focused states before major trades. Learning from Failure (Priority: 4/5): Early failure is common among successful traders but not predictive of future failure. Schwager notes many Market Wizards wiped out multiple times early in their careers, using failures as feedback to improve. Jason Shapiro, a contrarian trader, blew up accounts twice before developing proper risk management. The Importance of Not Trading (Priority: 4/5): Knowing when not to trade is critical. Schwager references a trader who achieved 900% cumulative returns over a flat S&P 500 by largely staying out during bear markets. He compares having a trading screen to having a slot machine.
Key Arguments: Markets are not efficient but act as if they are, making them very difficult to beat. Most people should buy low-cost index funds and hold long-term, acting as if markets were efficient. The world of traders divides into those with passion and developed methodology (who can profit) and those without (who should index). Success requires adaptability; strategies that work in one period may fail as markets change. Long-term realistic returns for top traders compound around 20-30% annually over decades, much lower than advertised '2% daily' systems. Early failure provides critical feedback and is not a permanent barrier to success.
Data Points: NASDAQ Internet Sector Rise: 600% - Gain over 18 months in late 1990s NASDAQ Internet Sector Crash: 85% - Loss over subsequent 18 months CUBA Fund One-Day Move: 85% - Moved from 15% discount to 70% premium based on fund name after Obama Cuba normalization announcement Michael Marcus Account Growth: $30,000 to $80 million - Early failure followed by enormous success Jeff Newman Returns: $2,500 to $150 million - Started 15 years ago, made $100 million in one recent year Long-Only Trader Performance: 900% cumulative vs. flat S&P - Over 12 years through two bear markets by not trading much
Pivotal Quotes: "Music is the space between the notes. And I love that quote because it's so apropos of trading. Because in a way, trading is the space between the trades." — Jack Schwager: Discussing the importance of knowing when not to trade "Having a growth screen on your desk is like having a slot machine. You keep on feeding it quarters all day long." — Jack Schwager (quoting Sokoda): Explaining why looking at prices intraday leads to overtrading "I will never, ever, ever not let my stop operate." — Jack Schwager (quoting Jason Shapiro): On the critical importance of risk management after early failures
Implications: For listeners, the podcast reinforces that trading success requires passion, hard work, emotional discipline, and adaptability—not get-rich-quick schemes. Most should index. For the industry, the discussion underscores how markets continue evolving, demanding constant innovation from both discretionary and systematic traders.
