AI stocks staged a comeback Friday after a rout that swept from Wall Street to Asia. But a single green session hardly settles the bigger question for investors heading into the weekend: Is this an overdue correction, or the beginning of an AI bubble bursting? Nvidia rose 2.78% to $186.64, after plunging 9.3% this Thursday. AMD also bounced to $449.04 following a 17.3% collapse a day earlier. Both stocks remain well below their October peaks, showing how little a sharp relief rally can repair.
