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 Chinese solar leader Trina Solar (NYSE: TSL) saw the sun set early when shares fell 10% in trading today.

So what: The move today actually has very little to do with Trina Solar specifically and has everything to do with LDK Solar (NYSE: LDK), which reported earnings last night, dragging the sector down. The trend of solar stocks posting better than expected earnings and lower than expected guidance continued, and the entire sector is feeling the pain.

Now what: What's curious about this move is that we didn't hear anything from the first quarter we didn't already know. LDK's earnings looked very similar to Trina and Yingli Green Energy (NYSE: YGE), which saw shipments down slightly and average sales price falling slightly as well. I am a solar investor, and I'm not panicking over today's move. We expected a slowdown in the second quarter and that's exactly what LDK said it is seeing.
