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: Hansen Natural (Nasdaq: HANS) popped 11% in intraday trading today after trouncing EPS expectations.

So what: Earnings per share of $0.59 grew an impressive 69% year over year and was well ahead of the consensus estimate of $0.49. Revenue grew 51% year over year, led by the company's Monster Energy brand.

Now what: The company is gaining U.S. market share in the growing energy-drinks market. It also plans to expand international distribution of the Monster brand this quarter. Both bode well for the outlook, though an easy comparable for the year-ago quarter suggests that Hansen can't maintain the first quarter's monster EPS growth rate.
