If you are a shareholder in JinkoSolar (JKS 1.21%)Abercrombie & Fitch (ANF -1.27%), or Veeva Systems (VEEV -0.10%), I have one word of advice for you: Don't make any rash decisions to buy or sell shares next week.

That's because all three of these stocks are reporting earnings next week, and all are heavily shorted -- or have a lot of investors betting against their short-term success. When those two factors combine, extreme volatility is usually the result. In fact, the last time I identified three such stocks, they moved an average of 14% following their quarterly releases.

While this might sound like an excellent time to try to time the market, nothing could be further from the truth. The fact of the matter is, volatility is the only event that seems highly likely. There's no way to know if that will result in higher or lower prices at the end of the day -- unless, of course, you're privy to some inside information (which would be illegal).

Instead, long-term shareholders should look in the following slideshow to see what they should really be looking for when their company reports, and what to ignore in the week ahead.
