NEW YORK ( TheStreet) -- Financial stocks were trading down on Wednesday despite a broader market rally. The Financial Select Sector SPDR ( XLF) was down 2 cents to $15.99. The big winner Wednesday was M&T Bank ( MTB - Get Report), which was trading up $1.07, at $87.85, on news that a Citigroup ( C), analyst raised his estimates on the bank as a result of its impending deal with Wilmington Trust ( WL). The biggest loser of the day is American International Group ( AIG - Get Report), which is trading down $1.62 to $57.31. It was reported that the insurer paid out $145 million in a multi-state workers compensation probe settlement and also failed to report $18.7 billion of policyholder guarantees at two property-casualty subsidiaries in 2008.
