Warren Buffett's upcoming 2025 letter to Berkshire Hathaway shareholders is generating anticipation, with analysts urging investors to pay attention to key figures within the letter. Buffett has indicated that Apple will remain the company's largest investment unless there are dramatic changes in capital allocation. Meanwhile, notable investor Michael Burry has adjusted his positions in Chinese internet stocks, reducing his holdings in Alibaba and JD.com while acquiring a stake in Pinduoduo, which now constitutes 4% of his Punch Card Capital portfolio. Burry is recognized for his successful prediction of the subprime mortgage crisis, and his recent moves reflect a strategic reshuffle in the tech sector.
