International vs US Equity: The 15-Year Gap
MSCI EAFE outperformed the S&P 500 in Q1 2026 after a 15-year US run. FC decomposes the gap into multiple, earnings, and currency, and frames the forward.
The MSCI EAFE Index is outperforming the S&P 500 year-to-date through mid-April 2026 by a margin that has not been seen in a meaningful way since 2017. Over the prior 15 calendar years, the S&P cumulatively out-ran EAFE by roughly 380 percentage points in US-dollar total return. That is a historic outlier. This post decomposes the gap, examines the Q1 2026 inflection, and frames the question every diversified investor is asking: is the regime turning, or is this a head-fake?
What Q1 2026 Changed
Year-to-date through April 20, 2026, MSCI EAFE has returned approximately 9% in US dollars against roughly 3% to 4% for the S&P 500. In local currency, EAFE is up about 3.5%. The difference between the local-currency number and the USD number is currency: the DXY dollar index has fallen roughly 5.8% year-to-date, and a weaker dollar mechanically boosts the USD-return of foreign-currency assets.
So the first thing to say about the Q1 2026 inflection is that it is a combination of three things: modestly better EAFE local earnings, a mild multiple expansion off a depressed base, and a non-trivial dollar decline.
The 15-Year Gap in Numbers
From January 2010 through December 2024, cumulative total return figures are roughly:
- S&P 500: +480%
- MSCI EAFE: +100%
- MSCI Emerging Markets: +35%
That kind of spread is not a statistical fluke. Over the same 15 years, the forward price-to-earnings multiple on the S&P expanded from roughly 13x to 21x. On EAFE it moved from 11x to 15x. Dividend yield on EAFE sits at 3.4% today versus 1.3% on the S&P, per the JPMorgan Guide to the Markets Q2 2026 edition.
Decomposition: Multiple vs Earnings vs Currency
We decompose the 15-year outperformance into three drivers. The exact split varies by methodology, but the order of magnitude is consistent across several research houses, including Research Affiliates capital market assumptions and the AQR Capital Management research library.
| Driver | Share of 15-Yr US Outperformance | Read |
|---|---|---|
| Multiple expansion | ~65% | S&P re-rated faster than EAFE across the full window; concentrated 2015-2021 |
| Earnings growth | ~25% | US corporate earnings grew faster, led by tech and large-cap profitability |
| Currency | ~10% | Dollar appreciation against EAFE currencies over the decade |
In our view, the 65% share from multiple expansion is the single most important number in this post. Earnings growth differentials alone would have produced a gap closer to 100 percentage points, not 380. The rest was paid for by a re-rating of US equities relative to the rest of the world. Re-ratings can reverse.
Is This a Regime or a Head-Fake?
We believe three tells separate a durable regime shift from a quarter of noise:
Tell 1: Currency persistence. If DXY stabilizes below 100 and earnings-growth differentials continue to narrow, the cumulative effect compounds. If DXY rebounds above 105, the currency piece of the Q1 2026 outperformance reverses mechanically. Predicting dollar direction is outside FC’s lane and outside most equity allocators’ lane; we treat DXY as an input, not a forecast.
Tell 2: Earnings revisions symmetry. FactSet Earnings Insight estimates EAFE Q1 2026 earnings growth at roughly +8% versus S&P at +12%. For the regime shift to be real, the gap between those revision trajectories has to narrow sustainably over multiple quarters, not just one.
Tell 3: Multiple compression symmetry. If the S&P de-rates from 21x to 19x while EAFE holds at 15x, the gap closes through US compression rather than EAFE expansion. That outcome looks different from one in which EAFE expands to 17x and the S&P holds. Both can drive outperformance; they imply different things about underlying earnings confidence.
How a Neutral Allocation Looks in 2026
The MSCI ACWI benchmark currently weights roughly 62% US, 28% developed international ex-US, and 10% emerging markets. Many US-based advisor-managed 60/40 portfolios have drifted to 70% to 80% US equity inside the equity sleeve because US outperformance created a passive overweight. A neutral, fully ACWI-matched allocation today would materially reduce US exposure relative to where most accounts sit.
That is a rebalancing decision, not a regime call. In our view, an allocator who wants exposure to the reversion thesis without taking a view on its timing should consider moving the equity sleeve back toward ACWI weights rather than making a discrete bet on EAFE outperformance.
Rebalancing vs Calling the Turn
We believe these are two different questions.
Rebalancing says: my target weight was 60% US and 40% international; drift has pushed me to 75% US; rebalancing back is discipline, not prediction. The timing is irrelevant. The historical evidence on rebalancing is that it produces modestly better risk-adjusted outcomes across most 30-year windows.
Calling the turn says: international is about to outperform US for the next decade; I am overweighting EAFE beyond neutral to capture it. The historical evidence on regime calls is weaker, and the path dependency is brutal if the regime takes three years to arrive rather than three months.
We have a modest bias toward rebalancing and a much more modest bias toward calling the turn. The 15-year gap was historic; mean reversion is a real force; but reversion can take a decade, and a portfolio overweighted to the losing side during that decade suffers opportunity cost regardless of how the math resolves.
In Our View
In our view, the US equity premium is still real but is no longer infinite. The multiple gap between the S&P and EAFE is wide enough that any mean reversion overwhelms the earnings-growth advantage over a long horizon. We believe the appropriate response for most advisor-managed accounts is to rebalance toward a target international allocation that matches the chosen benchmark, not to make a discrete bet on EAFE. Q1 2026 is an interesting data point, not yet a regime. We will revisit the framework after Q2 2026 earnings and after a full year of whatever DXY does next.
