Financial Winners & Losers: JPMorgan - TheStreet

Financial stocks rallied for the second day in a row, with

JPMorgan Chase's

(JPM) - Get Report

second-quarter earnings report serving as a catalyst.

The third-largest bank in the U.S. saw its income drop to $2 billion from $4.23 billion a year ago, but its

profit came in above expectations

even considering the bank's recent writedowns. The stock rose 13.5% to $40.80. The not-so-bad quarter was enough to fuel some optimism in the financial sector, pushing many small-cap names higher.

The JPMorgan news combined with another weak day for oil prices led the NYSE Financial Sector index to advance 4.5% to 6,268.98.

Investors shrugged off the weak results at

MGIC Investment

(MTG) - Get Report

, which reported a net loss of $97.9 million for the quarter. The mortgage insurer also said that it didn't expect to report a profit until next year. But it did record total revenue of $424.5 million, an increase of 15%, due to rising policy sales. Buyers pushed the stock up 43.6% to $5.89

BlackRock

(BLK) - Get Report

( MER) that would strengthen their relationship. Merrill owns a stake in BlackRock, and it had been rumored the brokerage may sell it in order to raise capital. Merrill's shares jumped 9.8% to $30.73.

Montgomery, Ala.-based bank

Colonial BancGroup

( CNB) catapulted 31% to $5.84 even after reporting a second-quarter loss of $8.9 million. Problem loans and charge-offs led to the loss as total assets dwindled by $1.3 billion. JPMorgan, however, upgraded the stock to overweight.

Another winner for the day was
