It's easier than you think being green -- at least when it comes to investing through exchange-traded funds.
The latest play on this increasingly crowded sector comes from
, which launched its
Market Vectors-Global Alternative Energy ETF
The new entry tracks the performance and yield of the
Ardour Global Alternative Energy Index (Extra Liquid)
, which includes stocks of companies all over the world involved in alternative and renewable energy technologies.
The listing comes at a time when you no longer have to own
An Inconvenient Truth
on DVD to be thinking about investing in alt-energy. The Supreme Court ruled last month that the Environmental Protection Agency has the power to curb greenhouse gas emissions. Many think this decision will eventually lead to regulations that make "cleaner" energy sources such as wind, solar and geo-thermal more attractive in the U.S.
And the European Union vowed in March that 20% of its energy needs will come from renewable sources by 2020.
The Market Vectors-Global Alternative Energy ETF is meant to give investors exposure to the most-widely held and traded "pure plays" in the sector. The Ardour Global Alternative Energy Index (Extra Liquid) screens 250 companies from the U.S., Europe and Asia that derive at least 50% of their revenue from alternative energy. Only the 30 stocks with the highest average daily trading volume and largest float-adjusted market capitalization actually make the index, which is rebalanced quarterly.
Van Eck's ETF sales director Adam Phillips says the biggest strength of the product is the diversification it offers. "In the alternative energy space, it is difficult to pick stocks, so an ETF is a perfect match," he says.
Danish wind power company
is currently the most heavily weighted component of the Ardour index, making up nearly 11%. Major U.S. companies include semiconductor manufacturer
. According to Van Eck, 77% of the companies in the index turn a profit.
Other recently-launched alternative energy ETF's include the
First Trust Nasdaq Clean Edge Fund
, which debuted in February, and the
PowerShares Cleantech Portfolio
, which started trading in October of last year.
