March was a volatile month for clean energy, with many of my picks reporting earnings. My 11 picks were down 4 percent on average since my last update (March 1st to April 5th), compared to a 9 percent decline in the Powershares Wilderhill Clean Energy Index (PBW), while the broad Russell 2000 index was flat. The hedged portfolio (see the original article for details) lost 5 percent.
