So what: Rosetta Resources hasn't released any news, so the two likely causes are oil prices and speculation. West Texas Intermediate and Brent crude futures are up 5% today, and the company's percentage of shares held short has been rising since oil prices started falling in 2014. The combination of the two -- rising oil prices are good for Rosetta's business -- could be leading to a bit of a squeeze on short sellers now looking to exit their positions.

Now what:Rosetta Resources reports earnings for the fourth quarter and fiscal 2014 on Feb. 24. Until then, the price is likely to remain relatively volatile, especially if oil prices continue to make big moves. Furthermore, it's important to remember that price moves like this aren't really a reflection of the business as much as the market's temperament. Before buying or selling shares, take the time to understand Rosetta's business, and how it fits in your portfolio.
