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 energy service provider PowerSecure International (UNKNOWN:POWR.DL) jumped as much as 18% in early trading after reporting earnings.

So what: Revenues jumped 85% from a year ago to $70.2 million and net income rose from $1.6 million to $2.1 million, or $0.11 per share. On a non-GAAP basis, which analysts compare to, the company earned $0.12 per share, $0.02 above estimates.  

Now what: The company hit an all-time high in backlog as well, which bodes well for future revenue and earnings. The stock is trading at a lofty 34 times this year's estimates, but two of the last three quarters it has beaten estimates, and with strong growth that's not a terrible value. I'd like to see a pullback before jumping in and more evidence of expanding margins after recent acquisitions.
