Amid yet another bearish session for the financial sector,

Downey Financial

(DSL) - Get Report

took a fall after

hopping on the third-quarter earnings-warning bandwagon.

Shares of the Newport Beach, Calif., bank sank 7.2% to $55.12 on word it will likely take an operating loss of $23 million, or 84 cents a share, as its credit-loss provision more than doubles to about $144 million (pretax). CEO David Rosenthal cited recent housing-market travails, which he said induced a "significant" rise in single-family loan delinquencies and losses from foreclosures.

Thornburg Mortgage

( TMA) slid again on a Keefe Bruyette downgrade to underperform, which comes on the heels of the mortgage lender's own third-quarter

bad tidings. The analyst set a $10 price target. Shares of the Santa Fe, N.M., firm were down 32 cents, or 2.6%, to $11.97.

Elsewhere, Bank of America said that

Genworth Financial

(GNW) - Get Report

has too much mortgage-insurance exposure and lowered the Richmond, Va., insurer to neutral from buy. Shares lost 4.1% to $30.33.

Ohio's

Progressive

(PGR) - Get Report

, another insurer, reported a 20.8% year-over-year drop in third-quarter earnings to 42 cents a share, or $299.2 million. Thomson Financial's estimates called for 37 cents a share, excluding special items. Net premiums written, moreover, slipped 2.7% year over year to $3.58 billion. Shares were recently down 7 cents at $20.09.

The

NYSE

Financial Sector Index, which tracks all but one of the above names, shed 0.8% to 9,632.04; the KBW Bank Index fell 1.2% to 108.83.

Sharply on the rise, meanwhile, was California-based

Fremont General

( FMT). Shares shot up 14.6% after Harbinger Capital Partners reported taking a 9% stake, or 7 million shares, in the lately beleaguered subprime-mortgage lender. Fremont stock was up 55 cents to $4.31.

U.S. Global Investors

(GROW) - Get Report

, of San Antonio, also rode high after saying its assets under management climbed nearly 6% to roughly $5.35 billion in the third quarter. Shares bounced more than 12% to $21.29.
