The iShares Core S&P U.S. Value ETF offers broad, diversified exposure to U.S. value equities with a low 0.04% expense ratio. IUSV's long-term returns and volatility closely match the Russell 1000 benchmark, but recent performance lags, with a 6% shortfall over the past year. Competitors VLUE and FVAL have outperformed IUSV since 2016, aided by cash-flow-based valuation and sector-specific methodologies.
