I don't think thats the case here. There was no real pump. However, industry leader, FSLR, had news yesterday that didn't help the industry's PPS, but wasn't that big of a deal either. It should have been already factored in the PPS accross the industry.
It looks more like a standard Friday profit taking and retracement back inside the bollinger bands.
Either way a very strong week. This will continue to rise or play sideways until the mid point bollie is touched. Earnings is next month. There was never a real reason for it to be as low as it was with the amount of assets the company has. It is actually trading like a typical solar play this week. a couple of spectaular up days followed by profit taking / consolidation. GTLA and I have held this stock since the IPO. ( strategically buying and selling of course) ;-) We should have a positive EPS this year as long as the industry has momentum.
