Billionaire investor Stanley Druckenmiller recently sold his stake in Nvidia, despite the company’s central role in the AI boom. He believes Nvidia’s stock price has become too high, making it vulnerable to a pullback. Druckenmiller acknowledged Nvidia’s impressive performance but argued that its valuation has become excessive, trading at over 50 times earnings. He cited concerns about competition from AMD and Intel, as well as potential regulatory risks. While Nvidia is a leader in AI infrastructure, Druckenmiller believes the market has priced in too much optimism, leaving little room for further upside. He emphasized the importance of valuation discipline, even for companies at the forefront of transformative technologies like AI.
