Bloomberg – Hedge funds increased short selling in U.S. renewable energy stocks to the highest level in a year, boosting bets against First Solar Inc. and Tesla Motors Inc. as government support for low-polluting technologies faltered.
Seventeen percent of the freely traded shares of the 35 U.S. stocks in the WilderHill New Energy Index are sold short, compared with 16 percent in October and 15 percent in August, data compiled by Bloomberg show. That’s almost four times the 4.4 percent short ratio of the Standard & Poor’s 500 index.
