Wall Street shed more than 200 points in trading late Friday, marking an end to a volatile week in the markets following a Federal Reserve speech on quantitative easing last week. 

"You can come up with any number of spurious reasons why stocks went down just as you can come up with any number of spurious reasons why it went up," said Reuters' Felix Salmon. "And it's fun, right? We've had a pretty boring stock market as of late, so it's good to get a bit of volatility in there."

This week also brought some good economic data on housing and spending, but The New York Times' Catherine Rampell says the data is mixed.

"Certainly the housing numbers have been very strong, so that's good news," she said. "But we got some bad numbers out of the European Union today...unemployment reached a record high. You have a quarter of young people out of work, looking for work. So maybe that's bumming people out. There are plenty of things to look for with bad news if you're looking hard enough."
