Wall Street got a reality check as a bruising selloff in technology shares fueled concern the artificial-intelligence frenzy that has powered the equity bull market might be overblown. Disappointing tech results spurred the worst drop for stocks since June, with the Nasdaq 100 falling 3.5% and briefly crossing the threshold of a technical correction. Intel Corp. slid the most in over four decades as its outlook missed estimates. Amazon.com Inc. slipped 1.4% on greater capital spending. The S&P 500 dropped 1.8%, breaching its key 100-day moving average.

For a quick recap of a bruising trade for big tech and equities broadly, hosts Tim Stenovec and Jess Menton speak with Bloomberg Markets Live blog managing editor Kristine Aquino.
