Micron Technology Inc.’s post-results selloff sent a fresh reminder to global investors about the risks inherent in bets on artificial intelligence chipmakers.

Days after leading AI chipmaker Nvidia Corp. slumped by nearly half a trillion dollars, Micron shares fell about 8% in extended trading after the memory maker offered a forecast that fell short of the highest estimates. In a sign of the extreme volatility in AI-related stocks, Micron’s news also triggered drops in South Korea’s two biggest companies, Samsung Electronics Co. and SK Hynix Inc., as fellow memory chip providers feeding the AI supply chain.
