FIW: Water Stocks Still Expensive Despite Weak Returns

First Trust Water ETF is downgraded to 'sell' due to persistent weak fundamentals and lackluster performance. FIW's static, market-cap-weighted portfolio results in low turnover but limited improvement in quality, growth, and value metrics since my last review in February. Key portfolio metrics—high P/E ratios, weak EBIT margins, and low ROIC—continue to undermine FIW's risk-adjusted returns.

These 3 Water ETFs Could be Quiet Winners From Infrastructure Spending

Data centers receive sharp criticism for their high water usage, but the impact on the broader water industry and for investors is also about infrastructure bottlenecks, regulation, and emerging technologies, among other things. Utilities companies must navigate significant changes when hyperscalers enter their territory—in some cases, a new data center operator may immediately become one of the largest customers in the region.

The $744 Billion Gap Nobody Is Pricing Into FIW And Why I'm Buying Against Wall Street

First Trust Water ETF (FIW) offers diversified exposure to U.S. water-related industrials, benefiting from structural CAPEX tailwinds and rising data center water demand. FIW's tiered weighting structure mitigates concentration risk, providing meaningful mid- and small-cap exposure beyond mega-cap dominance. Despite recent underperformance due to PFAS regulatory costs and market uncertainty, compulsory infrastructure upgrades and legislative support underpin the investment case.

FIW: Fundamentals Not Compelling For This $2B Water ETF

FIW is a well-established thematic water ETF with a 0.51% net expense ratio and $2.01B in assets under management. Established in 2007, it's delivered competitive returns with S&P 500 ETFs. However, except for the first few weeks of 2026, FIW has consistently trailed SPY with greater volatility. Overall, its small/mid-cap tilt has not helped, which is reflected in the fundamentals. With a $21B weighted market cap, FIW doesn't have the same quality features as SPY. However, its 23x forward P/E is elevated, and its portfolio-level earnings growth rates are low.

FIW: Water Valuations Recover, But Earnings Signals Disappoint

FIW is comprised of 36 companies operating in the potable and wastewater industry. Its expense ratio is 0.51%, and the ETF has $1.92B in assets under management. FIW has outperformed the S&P 500 Index over the last decade, but it's struggled recently. My last analysis in November urged caution based on high valuation and weak earnings momentum. This article provides an update to those fundamentals and highlights how FIW's valuation has improved. With growth rates staying stable, FIW's forward P/E dropped by 6%.

FIW: The Best Choice If You're Determined To Own A Water ETF

FIW is the top-performing water-themed ETF over the past decade, even rivaling the S&P 500 from the perspective of long-term returns. While water as an ETF theme is imperfect, FIW offers the purest economic exposure to the water sector available to investors. I rate FIW a hold, due to intrinsic challenges in capturing true water exposure, some poorly calibrated holdings, and more attractive long-term opportunities in other market sectors.

FIW: Water Remains Expensive

FIW holds 36 companies involved in the potable and wastewater industry. It's well established with $1.84 billion in AUM, but its 0.53% expense ratio is on the high end. Valuation is also concerning. FIW trades at 24.28 forward earnings and only offers 10.01% estimated earnings growth, both of which are worse than XLI, the broad-based Industrials sector ETF. I also found FIW's earnings momentum underwhelming. On average, its components delivered only a 3.47% earnings surprise last quarter.
