NEW YORK (

TheStreet

) --

Radian

(RDN) - Get Report

shares were leading financial stocks on Friday, continuing a bull rally that started earlier in the week when the mortgage insurer reported a surprise quarterly profit.

Radian was up 9.1% at $10 by early afternoon, having hit $10.12 earlier in the session. The stock has had trouble staying above the $10 mark, unable to close above that level consistently since April.

On Tuesday, the Philadelphia-based mortgage insurer reported a profit of $112 million, or 84 cents per share - the first quarterly profit in over a year. Radian has slowly started to recover by insuring new mortgage debt with better underwriting standards, while it still works through old, soured debt.

Competitors don't seem to be faring quite as well. Quarterly performance declined at both

PMI Group

( PMI) and

Genworth

(GNW) - Get Report

during the September period.

MGIC Investment

(MTG) - Get Report

narrowed its losses, but still remained in the red.

Nonetheless, Radian's results have helped lift competitors' stocks as well. Genworth, PMI and MGIC are up in a range of 5% to 10% since the close before Radian's earnings report, while Radian is up more than 25%.

Elsewhere in the financial sector on Friday, big bank stocks were trading higher, despite ongoing concerns about mortgage buybacks and a broader market decline.
