On CAPS, 96% of the 170 members who have rated Guggenheim S&P Global Water believe the ETF will outperform the S&P 500 going forward. These bulls include donjuansw and Trade4Profits.

Earlier this year, donjuansw summed up the bull case: "Potable water is scarce in many places already, and with the population boom in developing nations this situation is only going to get worse. Scarcity and pollution, coupled with population growth means that this long-term play will pay off."

Guggenheim S&P Global Water, in particular, sports a dividend yield of 2.1%. That's higher than that of other water ETFs such as PowerShares Water Resources (1%) and PowerShares Global Water (1.7%).

CAPS member Trade4Profits elaborates on the bull case:

Limited supply and high demand make industries surrounding water -- its supply, management, and exchange-traded funds -- attractive opportunities. Water is the one commodity where demand is not subject to the pressures of macroeconomics. Demand for clean water supply and improved water infrastructure is growing around the globe -- driven by a rising population, increased industrial demand, and the need to upgrade or replace the aging pipes carrying our water.

The 21st Century Commodity: Great [long-term] Investment.
