Why REITs Are Finally Outpacing the Broader US Stock Market in 2026

That is their strongest showing since 2021—and after years of underperformance, it demands a hard look at what changed.

The Numbers Tell a Clearer Story Than the Narrative

If the Morningstar US REIT Index holds its edge through December, we are looking at the first full calendar year of outperformance versus the broader market since 2021. Important caveat: over the trailing twelve months, REITs still lag. Seven months is a trend, not a victory lap. Context matters because recency bias will trick you into chasing the trade at precisely the wrong moment.

What is driving the reversal? Two forces. First, the artificial intelligence infrastructure buildout is funneling real dollars into data center REITs. Equinix, the largest third-party data center operator by revenue, is one of the index's top performers. Prologis is riding the same current through data center development alongside its core logistics business. Second, demographic tailwinds are quietly lifting senior housing. Welltower, the largest US REIT by mid-2026 market cap, posted a gain exceeding 30% in the first seven months, powered by aging baby-boomer demand and cost advantages tied to the Affordable Care Act.

Then there is Simon Property Group, which just reported its highest rent growth in a decade. High-end retail has recovered from the pandemic-era brick-and-mortar collapse, and Simon's portfolio sits squarely in that sweet spot.

Rates Are the Variable You Cannot Ignore

Morningstar analyst Kevin Brown flagged back in 2022 that rising rates would crush REIT returns. He was right. When Treasury yields spiked, income investors suddenly had bonds paying real yields—no leverage, no tenant risk, no capex surprises. REITs lost their yield advantage and saw borrowing costs spike, which froze M&A activity across the sector.

Here is the nuance most people miss: in early 2026, before the Iran conflict escalated in late February, the 10-year Treasury yield actually declined. That drop fueled significant February outperformance for REITs. Yields have since climbed again, pressuring the asset class. Yet the index has held its edge. That resilience in the face of rising rates is the real signal worth tracking.

Compare the yield on the Morningstar US REIT Index against the Morningstar US Core Bond Index and the opportunity cost math becomes obvious. If bond yields keep climbing, REITs need earnings growth—not just multiple expansion—to justify current prices.

Where the Valuation Math Gets Uncomfortable

Morningstar covers 26 constituents of the US REIT Index, representing roughly 70% of the index's market value. After the 2026 runup, several of the largest names—Welltower and Simon Property Group among them—are now considered richly valued by Morningstar equity analysts. You are paying up for demonstrated momentum, not buying cheap assets.

That is the binary choice sitting in front of you. REITs offer genuine asymmetric upside if rates stabilize and the AI infrastructure cycle continues to expand. But if you are entering today at stretched multiples, your margin of safety is thin. The disciplined move is to size the position so that a reversion to mean—REITs underperforming again in a higher-for-longer rate environment—does not derail your portfolio.

We have seen this movie before. The asset class looks compelling for seven months, capital floods in, and then rates or earnings disappoint. The question is not whether REITs can outperform. They just did. The question is whether you trust the catalyst to persist at these valuations, or whether you wait for the inevitable pullback to build exposure on your terms.
