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: In hot trading action today, shares of JinkoSolar Holding Co. (NYSE: JKS) jumped as high as 24% above last Friday's closing price on a stellar earnings report.

So what: Third-quarter sales tripled year-over-year and gross margins doubled, turning last year's loss into a very nice profit. Management expects to grow the company's market share and ramp up to even stronger results in the next quarter.

Now what: On the other hand, those shares also dropped at heart-stopping speeds in early morning trading before bouncing back again to stabilize somewhere in between. The market seems torn about solar stocks these days, being sent mixed messages by various players and struggling to make any sense of it all. It's telling that JinkoSolar's pop did not result in much of a halo effect on even its closest rivals.
