After Alphabet’s stock climbed roughly 4 percent over two days in mid-July, co-founder Larry Page’s net worth topped $300 billion, according to Forbes. The rally followed billionaire investor Warren Buffett’s acknowledgment in a CNBC interview that he had erred by not investing in Alphabet sooner. Buffett revealed he personally started Berkshire Hathaway’s first Alphabet stake last year, a position later expanded. When an interviewer asked why he favored Alphabet over other companies, Buffett responded that he does not prefer it as much as several other Berkshire businesses, though he added that Alphabet’s track record makes it a likelier winner than most securities sold through Wall Street. He also reaffirmed that Apple remains one of Berkshire’s top picks.
