American Express reported earnings that topped expectations Thursday, but "Fast Money" traders remain skeptical of its battered stock.
The credit-card company posted quarterly earnings per share of $1.23, excluding certain items, on $8.39 billion in revenue. But total sales and net income fell from the previous year, as a stronger U.S. dollar and the loss of an exclusive partnership with Costco Wholesale continue to drag on the company.
American Express shares fell about 4 percent in after-hours trading. They have plunged nearly 30 percent in the last year.
