Both are passive, low-cost index funds designed to capture the mid-cap segment of the U.S. stock market. The key distinction lies in their underlying indexes, which differ in composition and weighting methodology, leading to modest differences in yield, expense ratio, and reported volatility. VO is also slightly smaller in AUM at $106B compared to IJH's $124B, and VO's reported beta of 0.94 is modestly lower than IJH's 1.0, suggesting marginally lower sensitivity to market swings as their respective indexes move.
Who each is best for
IJH: Fits investors seeking exposure to a pure 400-stock mid-cap benchmark with a longer track record, starting in May 2000, and comfortable with a slightly higher expense ratio for the S&P methodology.
VO: Designed for investors prioritizing the lowest possible costs combined with a broader mid-cap universe, and who value the modestly higher current distribution rate alongside Vanguard's structure.
Key risks to know
- Index overlap and divergence risk. While both track mid-cap indexes, the S&P MidCap 400 and CRSP US Mid Cap are not identical. Holdings and weightings differ, meaning performance may diverge during periods when the two indexes behave differently—particularly during style rotations or valuation cycles that favor or penalize the stocks each captures.
- Mid-cap cyclicality. Both funds are sensitive to economic cycles; mid-caps tend to outperform large-caps in risk-on environments and underperform during recessions or flight-to-quality rallies. Neither fund hedges this exposure.
- Low current yields relative to broader market. Both funds distribute less than 1.5% annually. Investors seeking higher income will need to supplement with other holdings or accept lower current yield as a tradeoff for growth potential.
Bottom line
If you prioritize the absolute lowest expense ratio and a marginally higher yield, VO's 0.03% fee and 1.24% distribution stand out. If you prefer the longer inception history and a more established mid-cap methodology, IJH's decade-longer track record and S&P index affiliation offer familiarity. Both are quality core holdings for mid-cap allocation; the choice hinges on fee sensitivity and index preference rather than risk profile. Past performance does not predict future results.
