To illustrate Buffett's success: an investor who bought the S&P 500 at its absolute bottom in 1932 would have been outperformed by someone who simply held cash for 32.5 years and then bought Berkshire Hathaway in 1965. His compounding ability dwarfed even perfect market timing.

The S&P 500's self-cleansing mechanism, where failing companies are replaced by rising stars, makes it inherently safer over a century. However, Berkshire Hathaway's defensive posture, strong culture, and lower current valuation may offer superior downside protection over a shorter, 10-year horizon.

While Buffett's 22% annual returns are impressive, his fortune is primarily a result of starting at age 11 and continuing into his 90s. Had he followed a typical career timeline (age 25 to 65), his net worth would be millions, not billions, demonstrating that time is the most powerful force in compounding.

While Berkshire Hathaway is built for durability, the S&P 500 index possesses a unique long-term advantage: its self-cleansing mechanism. As dominant companies inevitably falter over centuries (e.g., NVIDIA), the index automatically replaces them with the next generation of winners. This constant rejuvenation could make the index a more resilient investment over an extremely long timeframe.

After underperforming by 40 points in 1999, Barron's questioned Buffett's ability. Most investors grew fearful and sold, just before Berkshire Hathaway doubled over the next decade while the S&P 500 remained flat. This highlights the danger of following herd sentiment during periods of poor performance.

Buffett's legendary wealth isn't just from being a smart investor, but from being a good investor for 80 years. The vast majority (99%) of his net worth was accumulated after age 60, highlighting the insane power of long-term compounding.

Over 58 years, Warren Buffett made ~400 investment decisions, but only 12 truly mattered—a 4% hit rate. The crucial insight is not just buying right, but holding these few exceptional businesses for decades, allowing compounding to work its magic.

The era of Berkshire Hathaway compounding at nearly 30% is over. A realistic expectation for the company's intrinsic value growth over the next 10-15 years is 10-12% annually. This rate aligns with its performance over the last quarter-century and sets a sober benchmark for current and future investors.

Even for the world's greatest investor, success is a game of outliers. Buffett made the vast majority of his returns on just 10 of 500 stocks. If you remove the top five deals from Berkshire's history, its returns fall to merely average, highlighting the power law effect in investing.
