Despite record sales and soaring profits, American Express' stock price fell 3.9%

With five consecutive quarters of rising revenue and profits, the credit-card juggernaut is on a roll. Certainly not without issues.

On Friday, American Express' stock AXP dropped 3.9% as the business reported yet another stellar quarter of rising revenue and earnings. Analyst predictions for even greater revenue and a quicker expansion that weren't reached were what kept the card issuer's shares down.

In contrast to expert expectations of $2.81 per share, the company reported record earnings of $2.89 per share. Wall Street had predicted $15.4 billion in revenue for the second quarter, but actual revenue was $15.1 billion. A noticeable slowdown in activity and worries about potential debt problems were two more troubling indicators.
