American Express Co said on Monday that U.S. credit card delinquencies rose in February as job losses accelerated and the economy deteriorated.

American Express shares were down 4 cents to $13.05 in afternoon trading on the New York Stock Exchange after the report. They had risen as much as 8 percent earlier in the session in a rally of financial services companies. The stock has lost one-third of its value in 2009.
