For instance, Berkshire bought stock in Alphabet (NASDAQ: GOOGL) (NASDAQ: GOOG) last year and has continued to buy shares this year, and Buffett, not current CEO Greg Abel, initiated the investment. One Wall Street expert says the answer might be Netflix (NASDAQ: NFLX), a megacap stock worth $305 billion. How Alphabet fits Warren Buffett's investment frameworkWarren Buffett's decision to buy Alphabet was somewhat surprising because, apart from buying Apple (NASDAQ: AAPL), Berkshire has largely avoided technology stocks during the past decade. Nevertheless, Buffett stepped outside his comfort zone when he purchased Apple stock in 2016 and he did so again with Alphabet stock in 2025. Even to someone like Buffett who is uncomfortable with technology stocks, such brand loyalty is an unmistakable sign of a competitive moat.
