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: Select Comfort (Nasdaq: SCSS) shares jumped 16% today after the company released earnings that beat expectations.

So what: In the third quarter, Select Comfort reported net income of $10.5 million or $0.19 per share on revenue of $160.1 million. Revenue beat Wall Street's estimate of $155.8 million despite closing stores during the quarter.

Now what: Select Comfort not only beat estimates on the top and bottom line, same-store sales were up 16% and the company increased full-year guidance. Select Comfort is on a roll, and I'm buying a strong future as the company improves stores and the overall economy recovers. This is one stock I could sleep well at night owning.
