"Warren Buffett's Annual Letter: Record Cash, Wall Street Warning, and Charlie Munger Tribute"

Warren Buffett pays tribute to his late friend and business partner, Charlie Munger, in his annual letter to shareholders, describing him as the "architect" of Berkshire Hathaway and a crucial figure in the company's success. Buffett also emphasized the importance of focusing on Berkshire's operating earnings and downplayed expectations for the company's stock performance, while expressing confidence in his successor, Greg Abel. Munger, who passed away in November at age 99, was remembered for his significant contributions to Berkshire Hathaway and his multifaceted career beyond the conglomerate.
