Fasten your seat belts, Fools. The three stocks I'm covering today are primed for big moves this week. That's because each of these stocks is (1) reporting earnings, and (2) heavily shorted. When these two forces combine, volatility is almost always the result.

But contrary to what you might think, I don't suggest trying to turn a quick profit on these stocks. That's because there's no way to tell if they will go up or down -- we only know that it'll probably be a wild ride. Instead, I suggest that existing shareholders of 3D Systems (NYSE: DDD), Iconix (NASDAQ: ICON), and GoPro (NASDAQ: GPRO) check out the slideshow below. That way, you'll be able to prepare yourself for volatility, and know what to really look for when your company reports earnings.
