This sell off is no surprise, Credit Suisse is probably unwinding their position (if they have the courage to follow their convictions). Of course, many (like myself) believe that their downgrade was short-sighted. In any case, this stock is not (and never has been) for the faint of heart. SOL has a very competent management, and a shrewd business strategy to weather this very hard industry climate.
Despite I am no friend of Credit Suisse and analysts I think their argumentation can't be shrugged off simply. Definitely their cash situation is lousy and they don't earn money. But if ruined prices for solar products return to reasonable hights REnesola is one of the bestpositioned and most promising companies. Hopefully that will happen before they run out of gas.
