Warren Buffett Has Called This 1 Investing Decision the Costliest Mistake of His Career. Here's How to Avoid It.
Even investing legends make mistakes sometimes.
Warren Buffett, renowned investor of Berkshire Hathaway, once admitted that his most costly investment mistake was buying the company in 1964 when it was a struggling textile business. He recounted this in a 2010 CNBC interview, stating that his $200 billion loss stemmed from purchasing the shares with the intention of reselling them at a profit.
However, Berkshire's management reneged on their agreement and lowered their offer at the last minute. Frustrated, Buffett acquired enough stock to take control of the company and remove the ineffective manager. This costly decision taught Buffett that Berkshire Hathaway was not a healthy investment. While few investors may face such a scenario, it’s easy to hold onto risky investments for the wrong reasons, such as when a business changes or fails to meet expectations.
It’s crucial to periodically review one’s portfolio and ensure every stock is still aligned with personal goals, risk tolerance, and investment thesis. If a company's performance declines or it loses its competitive edge, it may no longer be a sustainable investment. Moreover, buying stocks based on hype can be dangerous as market valuations are climbing and stocks can become overvalued.
In light of this, it’s advisable to double-check each stock’s fundamentals, such as a strong competitive advantage, competent leadership, and healthy finances. Once these aspects are confirmed, investors should be prepared to hold onto these stocks for an extended period, ideally several years or even decades. This approach ensures that investors are well-prepared for an eventual market downturn.
