American Express stock tumbles 7% as “AI scare trade” hits payments; what to watch before the open
American Express shares fell 7.2% to $321.24, among the steepest drops on the Dow, after a weekend research note warned AI could disrupt card fees and spending. The decline was not linked to company earnings but sparked broader selling in payments stocks, with Visa and Capital One also down. Investors are watching upcoming U.S. data and Federal Reserve signals for further direction.
