Wall Street posts worst drop since June as tech shares sell off

Wall Street suffered its worst drop since June after a bruising selloff in technology shares fueled doubts over whether the artificial-intelligence frenzy that powered the equity bull market is overblown. Disappointing tech results drove the decline: the Nasdaq 100 fell 3.5% and briefly crossed the threshold of a technical correction. Intel slid the most in over four decades as its outlook missed estimates, while Amazon slipped 1.4% on greater capital spending. The S&P 500 dropped 1.8%, breaching its 100-day moving average.
