They are history’s geniuses. But were they any good at investing? | The Story of Money Podcast

Key Concepts

• Market Mania/Bubble: A period where asset prices rise rapidly, driven by speculation and FOMO (Fear Of Missing Out), often disconnected from fundamental value (e.g., South Sea Bubble).
• Margin Trading: Borrowing money from a broker to purchase stock. It amplifies gains but also significantly increases the risk of total capital loss.
• GDP-Adjusted Wealth: A methodology used by financial historians to compare historical wealth by measuring it as a percentage of the total economy at that time, rather than just inflation-adjusting currency.
• Fixed Income Arbitrage: Exploiting price discrepancies between related financial instruments (e.g., bonds) to make a risk-free profit.
• Fundamental Analysis: Evaluating an asset's intrinsic value based on economic and financial factors rather than market sentiment.
• Bursar: The chief financial officer or treasurer of a college, responsible for managing its endowment.

1. Historical Case Studies: Brilliance vs. Investment Success

Sir Isaac Newton (The Scientist)

• The Context: Newton was a genius in physics and mathematics and served as Master of the Mint.
• The Trade: During the South Sea Bubble (1720), he initially made a massive profit (approx. £1.2 billion in today’s GDP-adjusted terms) by selling his 10,000 shares near the peak.
• The Failure: Succumbing to greed and FOMO, he re-entered the market at the absolute peak, liquidating his safe government gilts to buy more South Sea stock. He lost 40% of his fortune.
• Key Quote: "I can calculate the movement of stars, but not the madness of men." (Attributed to Newton regarding his market losses).

Winston Churchill (The Politician)

• The Context: A high-earning journalist and author who received massive advances (equivalent to ~£80 million in GDP-adjusted terms).
• The Methodology: Churchill engaged in high-turnover, speculative "day trading" on margin. He was influenced by the "go-getting" spirit of 1920s America.
• The Outcome: His intense trading volume—specifically during a nine-day period in October—wiped out his entire fortune, leaving him in debt despite his high income.

Charles Darwin (The Biologist)

• The Methodology: Darwin acted as a classic asset allocator. He successfully navigated the 19th-century railway boom and, crucially, shifted his portfolio into government gilts in the mid-1860s, avoiding the 1873 financial crash.
• Performance: He achieved an annualized real growth of 8.6% over 42 years, demonstrating the power of long-term, disciplined investing.

J.M.W. Turner (The Artist)

• The Methodology: Turner was a "fixed income arbitrageur." He identified a mispricing in a government debt exchange in 1829, where he could swap long-annuity bonds for new dated bonds to capture a 3.5% "free" profit.
• Perspective: Contemporaries viewed his obsession with money as "sordid" and "uncouth" for a man of his genius, highlighting the social stigma surrounding finance at the time.

John Maynard Keynes (The Economist)

• The Methodology: As bursar of King’s College, Cambridge, Keynes evolved from a high-frequency trader (holding periods <6 months) to a long-term, patient investor (holding periods >7 years).
• Performance: He outperformed the UK stock market by over 5% annually.
• Key Lesson: His success was attributed to his ability to adapt his style and learn from early failures in the 1920s.

2. Frameworks and Methodologies

• The "Sweet Spot" of Investing: The podcast argues that successful investing requires a balance: enough risk-taking to generate returns, but enough caution to avoid the "madness" of speculative bubbles.
• Evolution of Strategy: The transition from "timing the market" (short-term speculation) to "time in the market" (long-term holding) is identified as the hallmark of the most successful historical investors.
• Information Advantage: The speakers note that historical figures like Keynes benefited from connections and information access that would be classified as "insider trading" under modern regulatory frameworks.

3. Synthesis and Conclusion

The central question—whether high IQ and brilliance correlate with investment success—is answered with a definitive "no." While brilliance can help in understanding complex financial instruments or identifying arbitrage, it does not protect against human emotions like greed, FOMO, and overconfidence.

Main Takeaways:

1. Emotional Discipline: Even the greatest minds (Newton, Churchill) are susceptible to the "madness of crowds."
2. Adaptability: The ability to change one's investment style based on market conditions (as Keynes did) is more valuable than raw intellectual power.
3. The Danger of Margin: Speculating with borrowed money is a primary cause of financial ruin, regardless of one's status or intelligence.
4. Modern Application: For today’s investors, the lesson remains consistent: avoid the "meme stock" mentality, focus on fundamental value, and prioritize long-term strategy over short-term market timing.
