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 solar manufacturer JA Solar (NASDAQ:JASO) jumped 10% today after announcing a big project win.

So what: The company will provide solar panels for a 70 MW project being built by Shanghai CSET Co., Ltd. The company will install 20 MW of panels this year and 50 MW in the first quarter of next year.  

Now what: This is a nice win for JA Solar, but it's also business as usual. Ironically, the entire sale of 70 MW will be about equal to the company's jump in market cap of $42 million today. I don't see a major reason to change your investment thesis. More important will be the company's earnings report, which will likely come out late this month. U.S. manufacturers showed an incredible improvement in their reported earnings last quarter and JA Solar should do the same.
