I am currently holding only SPWR and FSLR as BRK invested in those two companies...SCTY came out and did well from the IPO, but I don't know what is happening...
I would not be surprised if some hedge fund is shorting this and will scoop up the cheapies...then pop it well above the other two...I know they are all over CA and CO and expanding...hard to say...I just picked up a bit for a day trade...
