For the last two days either some large investor is taking capital gains at lower rates this year (assuming rates go up for those making more than $200k/yr), or someone knows something that is not in the news. They did mention FERC investigations on last conference call, but didn't think it was material. A third possibility, but doubtful, is that price is being driven down prior to buyout offer.
I'm not sure about the capital gains theory: the purchase would have had to have been between Aug 2011 and Nov 2011 to make any difference. That's not a very big window. Another near-term catalyst from the conference call was the EPA generator rulings due out soon. Maybe word is leaking out about an unfavorable ruling ahead?
Stock up over 100% from its lowest point since this summer. I'll take the view and just assume this is just noise taking place with Sheep following the flow. Of course this is all conspiracy theories at best at this point. Great quarter and great business in a rapidly expanding and exciting market. Its pretty normal in these emerging markets that we see rapid price movements due to higher uncertaintities in what lies ahead.
