Buffett Says Goodbye: Why Long-Term Investing Still Wins

Warren Buffett, the legendary investor and longtime leader of Berkshire Hathaway, has published his farewell letter to shareholders as he steps down as Chairman and transitions to Chairman Emeritus. In the letter, the 96-year-old Buffett acknowledged a universal truth: "Father Time always wins." But he also noted that time has been generous to him, as evidenced by Berkshire's remarkable track record.

From 1965 to 2025, Berkshire's per-share market value compounded at an annual rate of 19.7%, turning a $100 investment into approximately $6.1 million. By comparison, the S&P 500, with dividends reinvested, compounded at around 10.5% over the same period, turning $100 into about $46,000. This staggering difference underscores the power of long-term compounding and disciplined investing.

The transition is now complete: Greg Abel took over as CEO on January 1, and Buffett's son, Howard, became Chairman on September 18. While this marks the end of an era, it also provides an opportunity to reflect on the investment philosophy that made Buffett one of the most successful investors of all time.

Buffett's approach was never about quick trades or chasing hot stocks. Instead, he emphasized owning quality businesses for the long haul. As he famously said, "If you aren't willing to own a stock for ten years, don't even think about owning it for ten minutes." His favorite holding period was "forever." This philosophy is exemplified by Berkshire's long-term holdings in companies like Coca-Cola (owned since 1988), American Express (since 1991), and Apple (since 2016).

For retail investors, Buffett's advice is clear: focus on durable businesses with economic moats, strong brands, and shareholder-friendly policies like dividends and buybacks. Alternatively, he has often recommended that most people simply invest in a low-cost S&P 500 index fund. In his 2013 letter, he advised putting 90% of cash in an S&P 500 index fund and 10% in short-term government bonds. The key is to stay invested through market cycles and let compounding work its magic.

Buffett's departure from Berkshire Hathaway marks a significant turning point for the company and its shareholders. While Greg Abel is a capable successor, the market will be watching closely to see if he can maintain Berkshire's culture of disciplined, long-term investing. Any perceived deviation from Buffett's strategy could impact the stock, but the company's diversified portfolio and strong balance sheet provide a solid foundation.

More importantly, Buffett's farewell letter serves as a powerful reminder of the principles that made him successful. In a world of instant gratification and meme stocks, his message is a clarion call for patience and consistency. The data is undeniable: over the long term, owning a diversified set of quality companies or a low-cost index fund outperforms most active trading strategies.

For investors in Berkshire's key holdings like Coca-Cola, American Express, and Apple, Buffett's endorsement of long-term ownership reinforces the case for holding these stocks. These companies have proven their ability to generate cash flow, maintain competitive advantages, and reward shareholders through dividends and buybacks. Their inclusion in Berkshire's portfolio is a testament to their quality.

Furthermore, Buffett's advice to invest in the S&P 500 is particularly relevant for retail investors who may not have the time or expertise to analyze individual stocks. By dollar-cost averaging into an index fund, investors can capture the broad market's growth over time, reducing the risk of poor stock selection. This strategy is simple, cost-effective, and historically proven to build wealth.

As we look ahead, the lessons from Buffett's career are more important than ever. Markets will always have ups and downs, but staying invested and focusing on the long term is the surest path to financial success. Whether you choose to emulate Buffett by picking quality stocks or follow his advice to buy the index, the key is to start early, stay consistent, and let time do the heavy lifting.
