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: Evergreen Solar (Nasdaq: ESLR) shares bounced 12% in late trading Monday on unusually high volume.

So What: After falling 11% on Friday Evergreen has rebounded nicely leading the solar sector upward. The market oversold solar on Friday and is now correcting that with a big bounce today.

Now What: Evergreen Solar has seen a sharp jump over the last few weeks as worries about slow demand in 2011 subside. With demand picking up and Evergreen's costs falling this stock will benefit and is one of my favorite small-cap solar companies. And with all the talk of U.S. and China fighting over renewable energy subsidies, it also doesn't hurt to have a "Made in U.S.A." label on your solar product. I'm not buying the short-term jump but this is a long-term trend upward for Evergreen Solar.
