Warren Buffett, the CEO of Berkshire Hathaway, is known for his impressive investment strategies. He has consistently outperformed the S&P 500 index over the past six decades. Since becoming CEO, Buffett has overseen a nearly 5,600,000% aggregate return in his company’s Class A shares.
This remarkable track record has made his investment decisions a topic of great interest among investors. However, Buffett keeps a big secret from Wall Street and his followers. He is under no obligation to reveal it until mid-February.
On rare occasions, Buffett secretly builds up sizable stakes in public companies. Berkshire Hathaway must file quarterly 13F forms with the Securities and Exchange Commission (SEC), which provide insights into the company’s investment activities. However, in three instances since the beginning of this decade, Buffett has requested and been granted confidential treatment when filing these 13Fs.
This allows Berkshire Hathaway to build up its stake in a company without other investors piling in and driving up the share price. In 2020, Berkshire had two positions that were given confidential treatment, which were later revealed to be Chevron and Verizon Communications. The third occasion occurred between July 1, 2023, and May 15, 2024, when Buffett took a sizable stake in property and casualty insurer Chubb.
Buffett’s secrets don’t always involve buying stocks.
