Time to hunker down, Fools. If you own shares of Winnebago Industries (NYSE: WGO), Blackberry (NASDAQ: BBRY), or Barnes & Noble (NYSE: BKS), get ready for a wild week ahead.

That's because all three of these companies are heavily shorted -- people are betting their share prices will fall -- and all three are reporting earnings. This is a recipe for volatility. If you don't believe me, take a peek at the three companies I highlighted earlier this month, which moved an average of 10% following the release of their respective quarterly reports.

But I don't think you should try and turn a quick buck on this volatility. That's because there's no way to know if these stocks are going to go up or down. Instead, I encourage current shareholders to check out the slideshow below to figure out what really matters, and what's just noise.
