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 mattress maker Select Comfort (Nasdaq: SCSS) jumped 11% after the company released earnings.

So what: Revenue increased 9% to $148.7 million, and earnings per share of $0.13 beat analyst estimates of $0.11. The company's outlook was even better, expecting earnings of $0.68 to $0.74 per share, topping estimates of $0.66.

Now what: This is the second straight quarter Select Comfort has hit our popped list, and earnings momentum continues to be strong this quarter. The outlook was very encouraging and management keeps confounding analysts by growing earnings faster than they expect. I was on the bandwagon after last quarter, and I will stay bullish on the stock after another strong quarter.
