Warren Buffett is widely known for his “forever” approach to stock investing—buying high-quality businesses with the intent to hold them indefinitely. Yet, this doesn’t mean he never sells. In fact, Buffett has repeatedly emphasized that while his preference is to hold long-term, he isn’t afraid to let go when the situation changes.
While iconic holdings like Coca-Cola and American Express remain in Berkshire Hathaway’s portfolio after decades, Buffett has also made high-profile exits. One notable example came in 2020, when he sold off airline stocks—including American, Delta, United, and Southwest—amid uncertainty brought on by the COVID-19 pandemic.
Buffett himself has clarified this approach, saying, “It’s not their inclination to sell,” referring to him and his partner Charlie Munger. Still, he admits they do sell, particularly when a company’s long-term competitive advantage erodes.
At the 2002 Berkshire Hathaway Annual Meeting, Buffett reflected on how changing business conditions can alter investment theses: “We probably had one view of the long-term competitive advantage of the company at the time we bought it, and we may have modified that.” He cited the newspaper industry, once considered a fortress of profitability, as an example of shifting fortunes that necessitated a reevaluation.
For companies that continue to show strong fundamentals, Buffett believes in holding on “for dear life.” But when the outlook deteriorates, he doesn’t hesitate to cut ties. His evolving strategy highlights a key lesson for investors: staying committed doesn’t mean being inflexible.
