The PowerShares WilderHill Clean Energy fund is generally acknowledged to be the granddaddy of the bunch. It was the first to market – in March 2005 – and has grown to be one of the largest, with $1.3 billion under management. Average trading volume is about 430,000 shares per day – ten times its initial turnover. The fund is up 15.71 percent since inception, settling down from a rocketing 34.83% rise in its first year.
The fund holds 42 stocks and is heavily weighted toward small-cap firms and includes stellar performers Suntech Power and Evergreen Solar. Although limited to U.S.-listed firms, this also includes the ADRs of some leading foreign firms, including Yingli Green Energy and JA Solar.
The PowerShares Global Clean Energy Portfolio takes a similar approach but also holds foreign-listed firms among 85 it holds. It has gained 13.24 percent since inception in May 2007. It is a measure of how hot clean tech is overseas that not a single U.S. firm in the 85-company portfolio is among the fund’s top ten holdings.
The small-cap tilt, however, leaves the fund vulnerable to considerable volatility – abetted by oil price and technology policy fluctuations - but this is partly muted by capping holdings to 4 percent.
The PowerShares WilderHill Progressive Energy Portfolio aggregates U.S.-listed companies improving or lessening fossil fuels use, such as clean coal, but also has some traditional plays as Sasol, a South African oil and gas company. The fund favors small cap (39%). Since its October 2006 launch the share price has risen 17.77 percent.
By contrast Claymore/LGA Green is overwhelmingly weighted to large cap firms. More than 90 percent fit that description, have an average market cap of $129.35 billion) and have exemplary environmental performance. Financials such as Citicorp represent the biggest sector (20.46 percent), but the fund top holdings also include General Electric (parent company of CNBC.com ), AT&T, and Chevron. The fund is up 6.50 percent.
One of the newer ETF entrants Van Eck’s Market Vectors – Global Alternative Energy ETF tracks a benchmark of 30 companies that derive at least half their revenue from alternative energy. Large-cap firms make up about 30 percent of its holdings, double the average ETF exposure. At least another 30% is in non-US companies. Since its May 2007 debut the share price has risen from $40.17 to $54.64.
But for all the buzz – and feel good factor – about green investing, these ETFs have drawn some criticism for their narrow focus.
“We have chosen not to slice the market with our ETFs,” says Rebecca Cohen of the Vanguard Group. “It is counter to our philosophy, We always believe that indexed funds should be broadly based, not dissected into such thin slices that it encourages high levels of trading or market timing; ETFs should be a buy and hold strategy, that covers a broader industrial group or broader market segment.”
She recalls people knocking on Vanguard’s door in 2000 to set up a mutual fund dedicated to the Internet but Vanguard refused. “People thought we were nuts at the time,” she says. “But we were proven right over the long-term.”
