PUW is based on the WilderHill Progressive Energy Index: “The Index is comprised U.S. listed companies that are significantly involved in transitional energy bridge technologies, with an emphasis on improving the use of fossil fuels. The modified equal-weighted portfolio is rebalanced and reconstituted quarterly.” PUW’s expense ratio is a reasonable .60.
According to a chart on Powershares’ website, the index would have outperformed the NASDAQ and the S&P 500 by a wide margin in the last five years, but with a little less volatility. The index has a beta of .92. Of course the results are hypothetical and do not take into account management and transaction fees.
