It is amazing to see these stocks move, take a look at CSIQ. I have been all over this name.
The rest of the usual suspect are moving as well:
SOLF ASTI HOKU JASO TSL LDK
My two favorites: STP & CSIQ. Check out this notable call on STP.
If I did not own any solar in my portfolio, and wanted to invest in this space, my top pick would be STP.
