NEW YORK (AP) — The sell-off for winners of the artificial-intelligence boom deepened Friday and yanked stock markets lower worldwide. Oil prices, meanwhile, continued to jump because of the war with Iran.
The S&P 500 fell 1% to finish its first losing week in the last three and only its third since the end of March. Just a couple days earlier, it had climbed within 0.5% of its all-time high.
