Buckle up, Fools! If you own shares of Pier One Imports (NYSE:PIR)BlackBerry (NYSE:BB), or Joy Global (NYSE:JOY), you have a week of wild swings in store. That's because all three of these companies are reporting earnings, and all three have stocks that are heavily shorted. Historically, that's a recipe for volatility.

If you don't believe me, check out the three stocks I last highlighted, which moved an average of 10% following their respective quarterly releases.

But don't be mistaken: I don't think you should try and profit from these short-term moves. There's no telling whether these stocks are headed up or down. Instead, I think that current shareholders should steel themselves for the week ahead by checking out the slideshow below to help separate the short-term noise from the long-term signals.
