Under the Hood: Why Value ETFs Are Not Created Equal

Many market participants have highlighted how value investing is back as the equity market rally broadened out beyond high-flying growth names. However, taking an index-based approach to the value style requires looking under the hood. Not all value ETFs are created equally.

A Tale of Two Benchmarks: Performance Divergence in Large-Cap Value

Consider the $83 billion iShares Russell 1000 Value ETF (IWD) and the $37 billion SPDR Portfolio S&P 500 Value ETF (SPYV). While both target large-cap U.S. value equities, their 2026 performance has diverged significantly. As of September 10, IWD was up 21% year-to-date. Meanwhile, SPYV gained only 11% over the same period. For perspective, the S&P 500 and the Russell 1000 parent indexes were up 11-12% for the year.

What explains this roughly 1,100-basis-point performance gap between the value ETFs? The answer comes down to index construction and specific criteria for inclusion.

FTSE Russell uses price-to-book ratios alongside medium-term growth forecasts to select value constituents for IWD, while S&P Dow Jones Indices evaluates book value, earnings-to-price, and sales-to-price ratios for SPYV.
