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

What Are Smart Beta ETFs?

The ETF industry has long been dominated by products based on market cap weighted indexes, a strategy created to reflect the market or a particular market segment.

Investors who believe in market efficiency should consider market cap indexes, as they replicate market returns in a low-cost, convenient, and transparent way.

However, some investors believe in the possibility of beating the market through exceptional stock selection, and choose a different type of fund that tracks non-cap weighted strategies: smart beta.

These indexes attempt to select stocks that have better chances of risk-return performance, based on certain fundamental characteristics or a combination of such characteristics.

This area offers many different investment choices, such as simplest equal-weighting, fundamental weighting and volatility/momentum based weighting methodologies; however, not all of these strategies can deliver superior results.

Fund Sponsor & Index

Managed by Invesco, PIO has amassed assets over $263.95 million, making it one of the average sized ETFs in the Industrials ETFs. Before fees and expenses, PIO seeks to match the performance of the NASDAQ OMX Global Water Index.

The NASDAQ OMX Global Water Index is designed to track the performance of companies worldwide that are creating products that conserve and purify water for homes, businesses and industries.

Cost & Other Expenses

When considering an ETF's total return, expense ratios are an important factor. And, cheaper funds can significantly outperform their more expensive cousins in the long term if all other factors remain equal.

It's 12-month trailing dividend yield comes in at 0.93%.

Sector Exposure and Top Holdings
