- PowerShares Water Resources Portfolio (PHO) focuses exclusively on U.S. companies that create products to conserve and purify water. It’s a U.S. fund that picks securities by market cap, but it then applies a modified liquidity-weighting to its holdings. PHO tilts more toward industrial names—about 64% of the portfolio—and less toward utilities—at 15%. It’s also the most liquid water ETF in the market today. It has some 37 holdings, with an expense ratio of 0.61%.
- Guggenheim S&P Global Water Index ETF (CGW) is a market-cap-weighted portfolio of global water utilities, infrastructure and water equipment and materials companies. It’s a broader and more vanilla take on the segment than PHO, with a 46-holding basket. Industrials represent about 48% of the mix, followed by utilities at 28%. CGW costs 0.64% in expense ratio.
- First Trust Water ETF (FIW) is U.S.-centric. The fund owns 36 of the largest U.S.-listed water companies, ranked by market cap and weighted equally within five tiers. The weighting scheme gives this ETF a tilt toward smaller-cap names. Industrials also lead here with a 60% allocation, compared to 17% tied to utilities. The ETF costs 0.57% in expense ratio.
- PowerShares Global Water Portfolio (PIO) is PHO’s global-in-scope counterpart. The fund emphasizes liquidity of its holdings, as does PHO, by employing a modified liquidity-weighting scheme of water-related companies. Industrials and utilities lead sector allocations at 36% and 30%, respectively, but PIO is relatively concentrated—its top five holdings represent about 35% of the portfolio. PIO also costs more at 0.76% in expense ratio.
- Summit Water Infrastructure Multifactor ETF (WTRX) is a fundamentally-weighted portfolio of global companies that derive most of their revenues from water-related businesses. The methodology looks at things like P/E ratios, EBITDA and return on equity. Industrials snag about 45% of the portfolio, while utilities represent about 30%. WTRX, which is less than one year old, costs 0.80% in expense ratio.
- Tortoise Water Fund (TBLU), the newcomer in the space, splits the portfolio into two. In one bucket, representing 70% of the mix, are companies that derive at least 50% of their revenues from water-related operations. The other bucket, at 30%, is made up of companies that derive less than half their revenues from water-related activities. The ETF’s tiered approach comes with the cheapest price tag in the segment: 0.40% in expense ratio.
These differences are behind the disparity in these funds’ performances, as the 12-month chart below shows (note WTRX launched last August):
