Led by banks, stocks pare gains to end week

Today looked like the traditional broke American spender of the past: Lower income, increased spending. We also saw waves of profit taking ahead of the weekend as the last two weeks have been some of the best moves seen in years.

Bank stocks have driven many of the market's big moves of late, and today was no exception. Citigroup (C) was the biggest loser among the 30 components of the Dow Jones Industrial Average, which fell 148 points, or 1.9 percent, to close at 7,776.
