Warren Buffett's Berkshire Hathaway has around 50% of its portfolio invested in tech titan Apple, owning about 5.8% of the company. Buffet, who is known for avoiding tech stocks, began buying Apple shares in 2016. The company attracts Buffett's investment due to its well-managed operations, strong competitive advantage, and dividend payments that share profits with investors. Apple's large installed base of devices and growing services revenue provide a solid moat against competition. Buffett also likes that Apple pays dividends, which have averaged $775 million annually for Berkshire.
