Warren Buffett's tenure as CEO of Berkshire Hathaway concluded at the end of 2025, leaving behind a 60-year record of compounded annual gains averaging 19.7%. This long-term performance exceeded the 10.5% compound annual return of the S&P 500 over the same period, establishing a benchmark that the company's new leadership must now address. The question for investors is whether the structural advantages that drove these returns will persist under Greg Abel, who has assumed the role of CEO.
The scale of Buffett's achievement is highlighted by a comparison with broader market indices. While the S&P 500 returned 10.5% annually over the 60-year span, the Nasdaq Composite, which launched in 1971, has recorded an 11.8% compound annual return since its inception. Buffett's portfolio sustained a 19.7% average annual gain for five decades, a level of consistency that his successor acknowledged in the 2025 annual report by describing Buffett as "arguably the greatest investor of all time." This historical performance created a high bar for future expectations, as maintaining such returns over another 20 to 60 years is considered statistically improbable.
Despite the unlikely prospect of replicating Buffett's exact returns, Berkshire Hathaway remains positioned to outperform the S&P 500 over time. The company's portfolio consists of well-run, efficient market leaders in essential and diverse industries, selected for long-term performance and value. These holdings are designed to navigate various market cycles, allowing the stock to show strength during downturns and outperform the market in both rising and falling conditions. This structural foundation suggests that while absolute returns may moderate, relative performance against the broader market is expected to continue.
Greg Abel has already begun reshaping the portfolio, making several key changes while managing a substantial cash pile. His approach is guided by a culture he has absorbed since joining the company in the early 1990s. In a shareholder letter, Abel emphasized that Berkshire's values form the basis of its operating framework, which shapes strategy and daily leadership. He noted that while his tenure will not match Buffett's 60 years, he intends for the company to be even stronger in 20 years, ensuring that owners or their descendants will be proud of the organization's continued stewardship.
