After a great January, the last three months have not been kind to clean energy stocks. While my model portfolios are still in positive territory (+5.4 percent and +0.9 percent for the unhedged and hedged portfolios, respectively), and are above my clean energy benchmark (The Powershares Wilderhill Clean Energy ETF, -3.4 percent), they have again fallen behind my broader market index, the Russell 2000 (+7.3 percent).
