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: Shares of clothing retailer rue21 (Nasdaq: RUE) rose as much as 10% today after the company released earnings and guidance.

So what: Revenue in the fiscal first quarter rose 19% to $205.6 million, just barely topping estimates. Net income was $11.6 million in the quarter, or $0.46 per share, $0.03 ahead of estimates. The company increased its earnings guidance by $0.02 to a range of $1.76 to $1.81 per share for the full year.

Now what: The numbers were good but not great, and the stock has settled down some from the initial pop. Same-store sales rose only 1.7%, and I'd like to see that drive revenue growth instead of just new store openings. Shares now trade at 16 times the top end of guidance, not a bad price considering the company's growth. I'm not excited enough about the growth to jump into shares today but if same-store sales improve, the stock could be a nice value.
