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 JinkoSolar (NYSE: JKS) dropped 10% today as the company was hit hard by analysts.

So what: Goldman Sachs (NYSE: GS) initiated coverage on JinkoSolar with a "sell" rating, following others to bash the solar sector. But Goldman wasn't bearish about all of solar, giving Trina Solar (NYSE: TSL) a "buy."

Now what: It seems like every day a new analyst downgrades a solar stock because of uncertain outlook for 2011. Today's news is really nothing new and just shows how the market reacts when big, bad Goldman gives a poor rating to a stock. If you believe in solar's future, this is a perfect buying opportunity, as the market will eventually run out of downward catalysts. The heavy short interest in JinkoSolar makes me think we'll see a bounce in the opposite direction one of these days.
