Market Highlights

A rebound in giant chipmakers lifted stocks as dip buyers emerged on speculation that the artificial-intelligence trade that has powered the bull market has more room to run. Following a selloff in one of Wall Street’s most-crowded bets, a closely watched gauge of semiconductor giants climbed the most since April 2025. The Nasdaq 100 advanced 3.4%. Microsoft Corp. surged 16%, adding roughly $450 billion to its value, the most by any stock in a single day. In late hours, Amazon.com Inc. jumped after its results while Apple Inc. retreated. A global rally in technology stocks gathered momentum as South Korean equities posted a record jump, with investors returning to the artificial intelligence trade after this week’s rout. The yen weakened, giving back some of its intervention-driven gains.
