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 Holding (NYSE:JKS) jumped 17% today after the solar manufacturer released fourth-quarter and full-year earnings.

So what: Total quarterly revenue rose 11.5% sequentially to $361.4 million on the back of a 13% increase in shipments. Net income was up about 60% sequentially to $27.1 million, or $0.96 per share, $0.03 ahead above analyst estimates.  

Now what: This is one of only a few profitable Chinese solar manufacturers, and it also has an outstanding balance sheet that will allow investment in the next generation of technology. That should allow margins to remain high and systems will bring in captive demand from a 1.1-gigawatt pipeline. This is one of the top stocks in solar and today's results show the power of JinkoSolar's business.
