Why VSS Could Be the Most Overlooked Long-Term Diversifier in International Investing

International stocks have outperformed U.S. equities for more than a year, with the MSCI ACWI ex US Index up about 40% over 12 months versus 36% for the Russell 3000, and 35% versus 17% over the past 16 months. The Vanguard FTSE All-World ex-US Small-Cap ETF (VSS) returned 30% in 2025 versus about 13% for the Vanguard Russell 2000 ETF, highlighting the appeal of lower valuations, a weaker dollar, AI adoption outside the U.S., and foreign infrastructure/defense spending. The piece is broadly constructive on non-U.S. diversification but is primarily commentary rather than a direct market catalyst.

Analysis

The market is beginning to reprice a structural regime change rather than a short-lived rotation: the combination of a weaker dollar, cheaper starting valuations, and fiscal impulse outside the U.S. is creating a broader earnings re-acceleration opportunity abroad. That matters most in small caps, where domestic economic sensitivity is highest and valuation dispersion is wider, so even modest macro stabilization can translate into outsized multiple expansion. The second-order effect is that passive U.S.-only growth exposure may now be crowded in both positioning and fundamentals, while non-U.S. small caps remain under-owned and mechanically supported by improving relative momentum.

AI diffusion is the underappreciated bridge between the headline thesis and the named beneficiaries. If capex and productivity gains keep spreading to international industrials, semis, and software enablers, the next leg of the trade is not just “international beats U.S.” but “cheaper AI exposure rerates faster.” That is particularly relevant for NVDA and INTC: both can benefit from any broadening of AI procurement beyond hyperscalers, but the real upside is in second-order demand from overseas enterprise and sovereign infrastructure budgets, which have been less fully capitalized into expectations.

The main risk is that this is still a highly crowded narrative trade in macro clothing. If the dollar rebounds, U.S. fiscal/growth data re-accelerates, or geopolitical stress triggers a global risk-off move, small-cap internationals will likely give back faster than large-cap defensives because liquidity is thinner and financing sensitivity is higher. Near term, watch whether outperformance persists on down days in U.S. equities; if it does, that would confirm genuine capital rotation rather than a simple beta rebound.

Consensus may also be underestimating how much of the move is a valuation catch-up rather than a permanent leadership shift. That means the trade can keep working for months, but the easy money is likely in the first-stage rerating; after that, returns will depend on actual earnings upgrades and not just multiple expansion. NFLX is a different angle: international currency translation and subscriber monetization outside the U.S. can provide a quieter earnings tailwind if the dollar stays soft.

Key Decisions for Investors

• Go long VSS vs short VTWO for a 3-6 month relative-value trade: the setup favors non-U.S. small-cap multiple expansion plus FX support, with downside limited if U.S. small caps merely stabilize rather than outperform.
• Add a tactical long basket of NVDA and INTC into any pullback over the next 1-2 months: the trade is not pure AI beta, but a hedge against the market underpricing overseas AI capex diffusion and non-U.S. enterprise demand.
• Express the macro view with long international equity exposure vs short U.S. dollar via a basket of EFA/EEM against UUP, targeting 6-12 weeks; risk/reward is best while positioning is still light and consensus remains U.S.-exceptionalism biased.
• For a higher-conviction relative trade, buy call spreads on VSS or EFA dated 3-6 months out and finance part of the premium by selling near-dated calls: this captures continued upside if the rotation persists while reducing entry cost if momentum stalls.
• Keep NFLX on a watchlist for a weaker-dollar beneficiary trade: if FX stays favorable into the next earnings cycle, international revenue translation can become a quiet earnings upside surprise rather than a headline-driven story.
