Beware these three stocks

Teens are a fickle lot and selling to teens can be a volatile business. That's what some of the biggest teen retailers are finding out right now.

American Eagle's stock took a hit this past week when its guidance lowered on its financials. The company said they expect profits will be $0.10 per share when they report on August 21. That's less than half of what Wall Street analysts were anticipating.

That sent American Eagle's shares down more than 15%. And, it took other teen retailers down. The markets reasoned that if American Eagle isn't selling as many clothes because teen employment is down, any other company dependent on teens should expect a tough time.

Sure enough, Aeropostale confirmed those suspicions on Thursday. It lowered guidance on its quarter's sales numbers. They expect their revenues to fall by 6% and from the previous year. And, more telling, the company's same-store sales will show a drop of 15%. In response, Aeropostale's stock is now down 9% this week.

A nervous market has taken down Abercrombie & Fitch and Urban Outfitters this week as well. Those two companies have seen their shares fall 5% since Monday.
