Best of MFM: Watch This Before You Invest Another Dollar
My First MillionKey Moments
Even the best investors have a 4% hit rate, suggesting index investing (like Berkshire Hathaway) is a viable path for long-term wealth, but avoiding emotional decisions is key.
Key Insights
Treating Berkshire Hathaway as an index, and dollar-cost averaging into its Class B shares, could yield a 128x return over 49 years with minimal effort, turning $10K into over $1.33M.
If you bought the S&P 500 when the PE ratio was 23, your annualized return over the next 10 years was historically between 2% and -2%.
Warren Buffett, with potentially 400+ investment decisions, highlights that only about 12 'moved the needle' for Berkshire Hathaway, indicating a 'god of investing' hit rate of roughly 3%.
The riskiest thing is the belief that there is no risk; market risk stems from human behavior, not just securities.
Consistent performance, even if only in the second quartile (between 27th and 47th percentile), can lead to top-tier results over time by avoiding 'shooting yourself in the foot' in bad years.
Investing is an infinite game where players don't win or lose, but rather decide to drop out, making long-term compounding crucial over short-term wins.
A simplified path to $1 million from $10,000
To turn $10,000 into $1 million (a 100x return), Mohnish Pabrai suggests a strategy that bypasses the currently overheated S&P 500. His recommendation is to treat Berkshire Hathaway as a de facto index and consistently invest (dollar-cost average) into its Class B shares. He posits that even a conservative 10% annual return, which he considers reasonable for Berkshire, would double an investment every seven years. Over 49 years, this translates to seven doublings, or 128 times the initial investment. This approach, dubbed 'plan B,' could grow $10,000 to approximately $1.33 million without requiring genius-level stock picking or incurring taxes due to the lack of dividends. This foundational amount, combined with ongoing savings from a day job and disciplined spending, forms a robust strategy for long-term wealth accumulation, even before 'plan A' aggressive strategies are considered.
The danger of high PE ratios in the S&P 500
Howard Marks points out a critical data correlation: when the S&P 500's Price-to-Earnings (PE) ratio is high, future returns tend to be low. Specifically, a JP Morgan chart from late 2024 indicated that if an investor bought the S&P 500 when the PE ratio was 23 (the approximate level at that time), the annualized return over the subsequent 10 years was historically between a mere 2% and negative 2%. This starkly illustrates that paying a higher price for stocks, relative to their earnings, significantly diminishes potential future gains and increases the likelihood of negative returns. This highlights the importance of market timing and valuation, suggesting that periods of high market valuations, often driven by optimism, are precisely when investors should be cautious.
Warren Buffett's 'dozen bets' and the power of patience
Mohnish Pabrai discusses Warren Buffett's shareholder letters, noting that in nearly 60 years of managing Berkshire Hathaway, Buffett identified only about 12 investment decisions that truly 'moved the needle.' Considering Berkshire's near-constant compounding at over 20% annually for decades, this implies an extraordinary hit rate of only around 3% for truly impactful investments. This statistic is particularly striking given Buffett's legendary status. Furthermore, Pabrai emphasizes that Buffett's success wasn't just in the 'buy' decision, but critically in the 'paint drying' or holding decision. Investments like Coca-Cola and See's Candies were held for 40-50 years. This suggests that the key to immense wealth accumulation, for even the greatest investors, lies in identifying a few exceptional businesses and holding them through thick and thin, rather than constantly trading or seeking incremental gains.
Emotional regulation and the contrarian mindset
Howard Marks stresses that the greatest risk in markets comes not from companies or institutions, but from human behavior. He advocates for a contrarian approach: being prudent when others are imprudent and terrified when others are carefree. This is because widespread irrational exuberance drives prices up, creating precarious situations, while widespread fear suppresses prices, creating opportunities. He shares a quote: 'When the time comes to buy, you won't want to.' This is because buying opportunities often arise during times of maximum uncertainty, pessimism, or fear—precisely when most people are inclined to sell or avoid investing. Doing the opposite requires significant psychological fortitude; it means acting on conviction when surrounded by negative sentiment and bad news. This behavioral discipline, rather than market prediction, is presented as a cornerstone of successful long-term investing.
The 'infinite game' of investing and avoiding implosion
Guy Spier introduces the concept of finite versus infinite games. Finite games have clear rules, boundaries, and a defined winner and loser (e.g., chess, football). Infinite games, however, have no defined rules or endpoints, and the goal is to keep playing rather than to win (e.g., life, culture, and crucially, investing). In an infinite game, one or more players simply drop out. Spier notes that many investment funds disappear within years, often due to internal 'implosions.' The key mistake is treating investing as a finite game where one seeks to 'win' quickly. Instead, understanding it as an infinite game emphasizes compounding, resilience, and avoiding catastrophic mistakes. This long-term perspective helps manage psychological pressures during inevitable periods of underperformance or market downturns.
Consistent mediocrity can yield extraordinary results
The 'route to performance' memo discusses a unique mathematical paradox in investing: consistently performing just above average can lead to being in the top 5% of managers. A client's 14-year track record of the General Mills equity portfolio, never deviating significantly from the second quartile (between 27th and 47th percentile), illustrates this. While not aiming for the top spot each year, by avoiding major losses ('shooting oneself in the foot') and maintaining a steady, positive performance, the portfolio could ascend to the top echelon over time. This 'unsexy' strategy of minimizing losers, rather than chasing heroic winners, is presented as a more reliable path to compounding wealth. Howard Marks uses the analogy of eating at a restaurant that is 'always good, sometimes great, never terrible' for 40-50 years to describe this sustainable approach.
The power of early compounding and regular saving
The importance of starting early and maintaining consistency in savings and investing is paramount for long-term wealth. For instance, a 22-year-old investing $10,000 in an index fund earning 10% annually (doubling every 7 years) would see that initial sum grow to $640,000 by age 64, after 42 years (six doublings). This is before considering additional annual savings, which also compound significantly. This explains how individuals like unassuming janitors can accumulate millions without hitting 'lottery ticket' investments, simply through disciplined saving and leveraging the power of compounding over decades. Even a significant income doesn't guarantee wealth if savings are not prioritized. The key is to 'start that engine early' and maintain contributions, ideally through tax-advantaged accounts like 401(k)s, where employer matches offer an immediate boost.
Mohnish Pabrai's 'circle the wagons' and avoiding foolishness
Pabrai discusses his 'circle the wagons' philosophy partly inspired by Buffett's focus on a few key decisions. He emphasizes that when one finds themselves in the fortunate position of owning a significant stake in a great business, the best action is often to do nothing more – just hold and let it compound. This means resisting the urge to constantly tinker or sell. He reflects on the story of two gas stations, where one proactively improves its offerings and the other fails to replicate even simple actions. Pabrai concludes with a stark self-admonishment, 'Don't be such a freaking idiot,' encouraging listeners to recognize opportunities and not foolishly neglect the proven principles of long-term investing and compound growth, even when faced with overwhelming data or the temptation to chase fleeting trends.
