Launched on 06/13/2007, the Invesco Global Water ETF (PIO Quick QuotePIO - Free Report) is a smart beta exchange traded fund offering broad exposure to the Industrials ETFs category of the market.

What Are Smart Beta ETFs?

Products that are based on market cap weighted indexes, which are strategies designed to reflect a specific market segment or the market as a whole, have traditionally dominated the ETF industry.

A good option for investors who believe in market efficiency, market cap weighted indexes offer a low-cost, convenient, and transparent way of replicating market returns.

If you're the kind of investor who would rather try and beat the market through good stock selection, then smart beta funds are your best choice; this fund class is known for tracking non-cap weighted strategies.

By attempting to pick stocks that have a better chance of risk-return performance, non-cap weighted indexes are based on certain fundamental characteristics, or a combination of such.

While this space offers a number of choices to investors, including simplest equal-weighting, fundamental weighting and volatility/momentum based weighting methodologies, not all these strategies have been able to deliver superior results.
