The bull must be on summer vacation. Stocks ended the week with losses.

The Dow Jones Industrial Average, the S&P 500, and the Nasdaq all fell Friday. The Dow dropped more than 100 points at one point in mid-day trading before recovering a bit. But there did not appear to be a clear reason for the sell-off.

Stock market trading is typically muted in August.

But even with the major indexes all shedding about 1% this week, the market hasn't lost all that much momentum. Stocks have still gained between 18% and 23% in 2013.
