First Trust's entry into the Water ETF game. Not much data since the ETF only started trading in early May. There are now three water ETFs you can choose from.

Water ETF with an international flavor (I always thought water had no flavor!) From thestreet.com: The Claymore S&P Global Water Index ETF (CGW - Cramer's Take - Stockpickr) has more of a global focus, with 72% of the fund invested in foreign stocks, as opposed to PHO's 15%. In fact, CGW invests in equities hailing from 14 different countries. Suez (SZE - Cramer's Take - Stockpickr) and Veolia (VE - Cramer's Take - Stockpickr) are CGW's two largest components, accounting for more than 9% each. That makes France the second-largest country by weighting in the fund at 19.58%. The U.S. is the largest country in the fund, accounting for 28%, but the U.S. does not dominate the fund as with PHO; the largest U.S. holding accounts for only 4% of the fund. CGW seems more directly focused on the third investment theme I outlined above, of bringing potable water to places that don't have enough, or any. Both Suez and Veolia are unambiguously water companies.

PowerShares Water Resources returned 10% over the past 12 months as of Tuesday. It is ahead 28% year to date and 25% since inception. nvestors see a huge opportunity for anything involved in water infrastructure. In just a year and a half, PowerShares Water Resources (AMEX:PHO - News) has become the flagship of the provider's 86 offerings. "There weren't many opportunities to buy stock in clean water providers in the open market," Bruce Bond, founder of PowerShares Capital Management, recently told IBD. "But investors understood it. Now it's our biggest, with $1.7 billion in assets." Source: Yahoo Finance article on water ETFs.
