GOOG stock plunges 13%: analysts cut PTs but remain bullish, betting on cloud growth

Alphabet shares GOOGL plunged 13% on Thursday's open after the Google parent reported weaker-than-expected third-quarter revenue and earnings, intensifying investor concerns that artificial intelligence could undermine its core search advertising business. If the losses hold through the regular session, the decline would mark Alphabet's steepest one-day drop since March 2020, when the stock fell 11.6%.
