The First Trust Water ETF (FIW), a thematic fund targeting water sector companies, holds $2.01 billion in assets under management with a 0.51% net expense ratio. Launched in 2007, FIW has delivered returns competitive with S&P 500 benchmarks but consistently underperforms the SPY ETF outside the first few weeks of 2026, accompanied by elevated volatility.
Performance Overview
FIW’s emphasis on small- and mid-cap holdings fails to outperform, reflected in its $21 billion weighted average market capitalization. This structure lacks the quality traits of SPY, contributing to lagging results amid market shifts.
Valuation and Earnings Analysis
Current metrics show FIW at a forward P/E ratio of 23x, considered elevated, alongside low portfolio-level earnings growth. S&P 500 earnings surprises remain soft this quarter, which could spur investor rotation into FIW’s smaller constituents.
Investment Considerations
Such a rotation offers a potential upside scenario. However, data indicates the ETF’s added volatility outweighs rewards, positioning it as a higher-risk option without compelling near-term appeal.
