For many investors, the passing of Labor Day marks their return to Wall Street and following their favorite stocks. For those who might've missed out on August's volatility, I have an antidote for you: three stocks that will probably make huge moves this week: Cracker Barrel (CBRL 2.96%)Park City Group (PCYG 0.86%), and Zayo (ZAYO). All three of these stocks will be reporting earnings, and all three have a relatively high percentage of their float being sold short. When these two forces combine, volatility is almost always the result. For perspective's sake, check out the three stocks I focused on two weeks ago, which moved an average of 12% following their respective earnings releases.

But instead of trying to profit from such short-term moves, I think current shareholders should instead steel themselves for the week ahead. Check out the following slideshow to see what really matters over the long-run, and what's just noise.
