Overview
IJH and VO are both broad mid-cap equity ETFs tracking different US mid-cap indexes. The funds target the same market segment but differ in index construction, fees, and dividend yield — making them close competitors for core mid-cap exposure.
How they differ
The first difference is index methodology. This means VO likely holds more positions and may capture a slightly different slice of the mid-cap universe. VO's distribution rate is also higher at 1.24% compared to IJH's 1.00%, suggesting either a higher current yield in its holdings or different dividend capture timing.
Third, the funds differ in scale and age. IJH is larger with $126B in assets and has been running since 05/22/2000, while VO holds $106B and launched 01/26/2004. VO's beta of 0.93 is slightly lower than IJH's 0.99, indicating marginally lower price volatility relative to the broader market, though the difference is minimal.
Who each is best for
IJH: Fits investors seeking the most tightly defined mid-cap exposure through a fixed 400-company index, paired with the longest track record and the confidence of iShares' scale.
VO: Designed for cost-conscious investors who value the lowest possible expense ratio and want exposure to a broader mid-cap universe that may capture a wider range of growth and value opportunities within the segment.
Key risks to know
- Index composition overlap risk. While both track mid-cap stocks, their underlying indexes weight and select companies differently. Holdings likely overlap substantially, but divergent index methodologies could lead to meaningful performance gaps during market rotations that favor value over growth or vice versa.
- Mid-cap volatility. Mid-cap stocks are more volatile than large-cap but less volatile than small-cap. Both funds carry a beta near 1.0, meaning they will tend to amplify broad market downturns and rallies; neither offers downside cushioning relative to the overall market.
- Dividend yield dependency. Both funds distribute at modest rates (1.00%–1.24%), so they rely heavily on price appreciation for total return. A sustained decline in mid-cap earnings or valuations would erode NAV and leave limited income cushion.
Bottom line
VO edges out on total cost of ownership with a lower expense ratio and higher current yield; IJH offers a longer operating history and the specificity of the S&P 400 methodology. If minimizing fees and capturing a broader index universe matter most, VO's advantage is material over a long holding period. If you prefer the tighter index structure and longest historical track record, IJH delivers comparable exposure at a negligible cost difference. Past performance doesn't predict future results.
