PowerShares Global Clean Energy Portfolio (NYSEArca: PBD)

Current Price: $11.90

YTD: Up 47%

Comment: Another clean energy play with a dash of SolarCity and Tesla (a combined 3.4% of the ETF’s weight).  Roughly 38.5% of PBD’s portfolio is tilted to small-caps. Things could get interesting for PBD if it takes out its third-quarter 2011 highs.
