Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Hibbett Sports (Nasdaq: HIBB) shares jumped 13% today after the company announced earnings that beat estimates.

So what: The operator of sporting goods stores saw revenue bounce 15% higher, and earnings per share of $0.44 were well above the Wall Street estimate of $0.38. Rival Dick's Sporting Goods (NYSE: DKS) has also seen strong demand, and both plan to add stores next year.

Now what: Plans to increase Hibbett's footprint by 40 to 42 stores next year were higher than previously announced, and bode well for more growth. The sporting goods category is on a roll as consumers decide to spend a little more to outfit their favorite athletes. I don't see the momentum stopping anytime soon as the whole sector moves higher.
