Exchange-traded funds tracking financial names were among the few losers in a banner week on Wall Street.

Disappointing earnings and more writedowns held the financial ETFs back.

For the week, the First Trust Financial AlphaDex ( FXO) ETF was lower by 2.7% to $15.69. The iShares S&P Global Financials ( IXG) ETF eased 0.4% to $82.02. The Financial Select Sector SPDR ( XLF) ETF lost 0.1% to $29.33.

On Wednesday, Morgan Stanley ( MS) reported a fourth-quarter loss of $3.61 a share and said it had to write down the value of its mortgage-related assets by $9.4 billion. The following day, Bear Stearns ( BSC) posted a quarterly loss, the first in the company's history, due to a $1.9 billion writedown from mortgage-related losses.

Goldman Sachs ( GS) handily beat Wall Street's fourth-quarter earnings and revenue estimates on Tuesday, but still finished lower for the week.

Additionally, Standard & Poor's cut its credit outlook Wednesday for MBIA ( MBI) and Ambac ( ABK) to negative from stable.

On the winning side, a blockbuster report from Research In Motion ( RIMM) boosted the Wireless HOLDRs ( WMH) ETF. The BlackBerry maker posted third-quarter earnings and revenue Friday that more than doubled from a year ago. The Wireless HOLDRs ETF finished up 2.8% at $73.70.

Fellow tech giant Oracle ( ORCL) reported a fiscal second-quarter profit that jumped 35% from a year ago, surpassing Wall Street's estimates. The Software HOLDRs ( SWH) finsihed the week higher by 2% at $44.37.
