What do a furniture and electronics store, a fast-casual restaurant, and a video technology company all have in common? 

Usually, the answer is "Not much." But this week, shares of three such companies -- Conn's (NASDAQ:CONN)Zoes Kitchen (NYSE:ZOES), and Ambarella (NASDAQ:AMBA), respectively -- are set for big moves on Wall Street. That's because all three are heavily shorted, and each is due to report earnings this week.

But don't try and use this information to turn a quick profit; there's no way to know whether these stocks are headed up or down. All we know is that they're primed for big moves. If you don't believe me, check out the three stocks I singled out two weeks ago -- they moved an average of 8% following their earnings releases.

If you already own shares of these three, I suggest checking out this slide show to see what you should be watching and what is just short-term noise.
