Capital One ( COF) gained a day after the lender reported a 39% gain in fourth-quarter profits. Shares of the Virginia-based lender rose even though CapOne offered earnings guidance for 2007 that falls well below the current Thomson Financial estimate. The stock may have gotten a lift from a Friedman Billings analyst who reiterated his outperform rating on the stock. Shares were up $3.18, or 4.2%, to $79.

Community Bancorp ( CBON) shares climbed after the Nevada-based bank said fourth-quarter earnings rose 35% to $5.4 million, or 54 cents a share. The lender beat the consensus forecast by 4 cents. Shares were adding $2.35, or 8%, to $31.95.

Knight Capital ( NITE) erased some of Thursday's hefty losses after a CIBC World Markets analyst upped his rating to outperform on the stock. On Thursday another analyst voiced concern about a slowdown in Knight's "core" trade execution business. Shares were gaining 55 cents, or 3%, to $18.98.

E*Trade ( ETFC) fell after a Citigroup analyst said there were some holes in the online broker's fourth-quarter profit report. The analyst said E*Trade's earnings actually came in 2 cents below the consensus estimate of 39 cents a share, after factoring out restructuring costs and other items. E*Trade, late Thursday, reported earnings of $176.7 million, or 40 cents a share. A year ago, it earned $129.4 million, or 33 cents a share. Shares were down 54 cents, or 2.2%, to $24.17.
