Short interest in First Solar continues to decline, while shorts maintain their focus on SunPower. Nearly a third of SunPower’s shares are now short, and just looking at the share price chart for the past 12 months indicates that the shorts may be on to something here.
The big change in short interest for the Chinese makers is the sharp jump at both JA Solar and Yingli Green Energy. For the short sellers who jumped on JA Solar in late May, the payoff has been good because the stock has dropped by about a third. Yingli’s slide has been smaller, but still more than 15%. The Chinese government’s recently announced support for new solar projects in the country has stabilized somewhat the share prices for China’s solar makers, so it may be time for the shorts to bail on these stocks.
