Fears of an artificial intelligence bubble are continuing to roil the markets; while AI was one of the biggest drivers in the stock market over the last three years, leading to a long bull market in the S&P 500 ($SPX), AI stocks are struggling in 2026. Meanwhile, energy and consumer stocks are getting more action as investors shift some of their dollars away from AI.
Renaissance Technologies is among those moving money around. The hedge fund reduced its exposure to Nvidia (NVDA) in the fourth quarter from 5.63 million shares to fewer than 900,000. The fund also completely exited its stake in Meta Platforms (META), and cut its Alphabet (GOOG) (GOOGL) shares from 2.61 million to just 296,000.
