Milliman Healthcare Inflation Guard ETF (MHIG)

The Milliman Healthcare Inflation Guard ETF (ticker MHIG, launched April 2026) is an actively managed fund designed to track and keep pace with rising healthcare costs in the United States. Rather than chasing stock returns or trying to beat a traditional benchmark, MHIG simply aims to earn whatever the healthcare sector is inflating by—meaning its investors get back, on average, what they would lose to healthcare cost increases.

Healthcare costs rise faster than general inflation nearly every year. A family paying $5,000 for a medical procedure today might pay $5,550 next year, then $6,100 the year after. Those increases compound over decades. Most investors hedge that risk by holding healthcare stocks, which tend to rise when treatment costs go up. But stocks are volatile, and healthcare stocks are no exception. MHIG takes a different approach: instead of betting on health-sector equities alone, it builds a diversified portfolio across asset classes to stay in sync with the inflation rate that matters most to individuals and families.

What MHIG holds and how it shifts

The fund is actively managed, not tied to a single static index. Portfolio managers use Milliman’s Health Trend Guidelines—an industry-standard model built on decades of healthcare claims and cost data—to guide allocation decisions. On any given day, the fund might hold a mix that looks something like 40% in health-related stocks, 35% in bonds (including Treasury Inflation-Protected Securities and corporate bonds), and 25% in alternatives like commodities or liquid strategies. But those percentages move as economic conditions change and as inflation forecasts shift.

The intentional diversification across stocks, bonds, and alternatives serves a purpose: when one asset class is losing value, others may be gaining. Traditional stocks tend to fall in deflationary downturns; bonds held to maturity deliver their stated return regardless of market swings; commodities and inflation-hedging alternatives sometimes rally when stocks stumble. By mixing them, MHIG seeks to smooth the ride while still earning enough to match healthcare cost growth.

The mechanics and the risk

MHIG is not a passive index fund. Managers must analyze healthcare cost trends, economic data, and the performance of different asset classes constantly. That active management carries a cost: the fund charges 0.55% annually (as of its 2026 launch, with a temporary fee waiver through April 2027). For an investor holding $100,000 in MHIG, that comes to about $550 per year.

The genuine risk is that MHIG may not actually deliver inflation-matching returns over every period. If healthcare costs surge suddenly—say, from new drug approvals or a pandemic—the fund’s models may lag. Conversely, if innovation brings healthcare costs down faster than expected, MHIG’s hedging strategy will feel like dead weight. The fund is also young and has limited track record. And like all actively managed funds, MHIG depends on portfolio managers’ skill; if those managers make poor allocation calls, the fund underperforms its own stated goal.

Another subtler risk is concentration: all the holdings are, one way or another, exposed to the same thing (healthcare inflation). If the entire healthcare sector faces structural headwinds—say, government price controls—MHIG has no refuge.

Why someone might own it, and how to research

MHIG appeals to investors who expect healthcare costs to keep rising (a safe bet historically, though not guaranteed), who want a smoother ride than health-sector stocks alone offer, and who are willing to pay active-management fees for that diversification. Retirees and individuals funding long-term care are natural candidates, as are pension funds that need to hedge healthcare liabilities.

To evaluate MHIG yourself, start with the fund prospectus on the Milliman Funds website. It will show you the current allocations, the exact rules portfolio managers follow, and the full list of risks. Watch the fund’s quarterly fact sheets to see how allocations shift over time—that tells you whether the managers are tactically adjusting to new economic data, or just leaving the portfolio static. Compare the fund’s trailing returns against the inflation rates published by the Bureau of Labor Statistics for healthcare specifically. And check the fund’s total assets—funds with very small asset bases sometimes shut down or merge, creating unexpected tax events for shareholders.

For anyone hedging a large expected healthcare expense or thinking about long-term care costs, this fund offers a cleaner hedge than owning health-sector stocks outright. For everyone else, it is a specialized tool, not a core holding.
