Teen-apparel chain American Eagle Outfitters tumbled the most in more than three years after saying second-quarter profit was less than it forecast.
Disappointing sales of women’s clothing were at the heart of the problem.
The shares slid 12 percent to $17.57 at the close, the most since May 26, 2010. The company said earnings for its most recent quarter were as much as 52 percent lower than its forecast.
