Solar stocks are rallying again, likely thanks to year-end short-covering (previous). LDK +9.2%. STP +6.8%. CSIQ +3.6%. GTAT +4.6%. YGE +4.7%. MEMC (WFR +3.2%) is in the news: the company announced board members John Marren and William Stevens, each of whom have served for 11 years, are retiring (this should strengthen the hand of activist firm Atlai Capital), and that its SunEdison unit has sold 24MW of solar projects to Canadian Solar (CSIQ +3.6%).
