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 EnerNOC (Nasdaq: ENOC) were down more than 13% today following the company's third-quarter earnings report after yesterday's closing bell.

So what: EnerNOC, which helps companies efficiently manage their energy usage, reported better-than-expected revenue ($162.8 million, up 58%) and earnings ($1.67 per share, up 65%). However, guidance for its next quarter disappointed Wall Street. In the conference call, management said revenue and earnings are "trending toward the midpoint of our previous 2010 guidance range."

Now what: Investors looking toward longer-term catalysts should keep an eye on international expansion, which started in the U.K several months ago. President and co-founder David Brewster said on the call that EnerNOC has "established a solid team and believe we are in a similar development stage in the U.K. as we were in New England in 2004 or Texas in 2009 and are excited by the near-term growth opportunities we see."
