IYH vs VHT: Which Is the Better Pick in 2026?

Overview

IYH and VHT are both passively managed healthcare ETFs tracking different U.S. healthcare market indexes. IYH follows the Dow Jones U.S. Health Care Index, while VHT tracks the MSCI US Investable Market Health Care 25/50 Index. The funds differ substantially in size, cost, and yield, despite serving the same broad sector exposure.

How they differ

VHT is nearly five times larger by assets ($19.4B vs. $3.88B) and charges a significantly lower expense ratio of 0.09% compared to IYH's 0.37%—a 28 basis point advantage that compounds over time. VHT also delivers a higher distribution yield at 1.23% versus 0.90%, though both pay quarterly. The underlying indexes differ in composition methodology: VHT's MSCI index applies a 25/50 weighting cap to limit concentration in large holdings, while IYH's Dow Jones index uses market-cap weighting without such constraints. Beta is nearly identical (0.54 for IYH, 0.58 for VHT), so volatility relative to the broader market should feel similar.

Who each is best for

IYH: Fits investors seeking established healthcare index exposure with a longer fund history (inception 06/12/2000) who are indifferent to the cost differential and don't require maximum income distribution.

VHT: Designed for cost-conscious investors prioritizing low fees and higher income, particularly those building long-term sector positions where the 0.09% advantage and 1.23% yield make a meaningful difference over decades.

Key risks to know

• Index concentration risk: IYH's market-cap weighting may concentrate exposure in mega-cap names (typically pharmaceutical and insurance giants) more heavily than VHT's 25/50 capped structure, which constrains single-holding weight. Over time, this can create outsized sensitivity to the performance of a few large positions.

• Healthcare regulatory exposure: Both ETFs are vulnerable to changes in drug pricing policy, patent legislation, and reimbursement rates. Shifts in political winds around healthcare reform can rapidly alter sector valuations regardless of underlying fund mechanics.

• Sector-level valuation risk: Healthcare valuations are historically sensitive to interest-rate moves and recession concerns. Rising rates can suppress multiples on lower-yield healthcare services businesses, while recession fears can crimp discretionary spending on certain treatments.

• Fee drag divergence: The 28 basis point annual fee difference between the funds compounds meaningfully over a 20+ year horizon, potentially creating a 5%+ cumulative return gap assuming equal index performance.

Bottom line

If cost efficiency and maximum income are priorities, VHT's lower expense ratio and higher yield make a material case given its size and liquidity. If you prefer a longer-established fund and aren't sensitive to the fee difference, IYH delivers comparable sector exposure with a simpler weighting structure. Past performance does not guarantee future results; the choice hinges largely on fee sensitivity and the concentration characteristics of each underlying index.
