US vs International: The Big Question
Should you invest only in U.S. stocks, or should you include international stocks? This is one of the most debated questions in investing.
The U.S. has been the best-performing developed market for over a decade. But history shows that leadership rotates. Today's winners become tomorrow's laggards, and vice versa.
Let's look at VTI (total U.S. market) and VXUS (total international ex-US) and figure out how to combine them.
Quick Comparison
| Feature | VTI | VXUS |
|---|---|---|
| Full Name | Vanguard Total Stock Market ETF | Vanguard Total International Stock ETF |
| Index | CRSP US Total Market | FTSE Global All Cap ex US |
| Holdings | ~4,000 US stocks | ~8,000 international stocks |
| Countries | 1 (USA only) | 46 countries |
| Expense Ratio | 0.03% | 0.07% |
| AUM | ~$400 Billion | ~$70 Billion |
| Dividend Yield | ~1.4% | ~3.0% |
| P/E Ratio | ~24x | ~14x |
VTI: Total U.S. Stock Market
VTI gives you exposure to the entire U.S. stock market - about 4,000 companies representing virtually 100% of the investable U.S. market.
VTI Top Holdings
| Rank | Company | Weight | Sector |
|---|---|---|---|
| 1 | Apple | 6.2% | Technology |
| 2 | Microsoft | 5.8% | Technology |
| 3 | NVIDIA | 4.5% | Technology |
| 4 | Amazon | 3.4% | Consumer Discretionary |
| 5 | Alphabet (Class A) | 2.0% | Communication |
| 6 | Alphabet (Class C) | 1.7% | Communication |
| 7 | Meta Platforms | 1.9% | Communication |
| 8 | Berkshire Hathaway | 1.6% | Financials |
| 9 | Tesla | 1.4% | Consumer Discretionary |

| Energy | 4.0% |
| Utilities | 2.5% |
| Real Estate | 2.0% |
| Materials | 2.0% |
Key observation: VTI is heavily tilted toward technology and growth companies. The "Magnificent 7" tech giants make up over 25% of the fund.
VXUS: Total International ex-US
VXUS gives you exposure to developed and emerging markets outside the United States - about 8,000 companies across 46 countries.
VXUS Geographic Allocation
| Region | Weight | Key Countries |
|---|---|---|
| Europe | 39% | UK, France, Germany, Switzerland |
| Pacific | 27% | Japan, Australia, Hong Kong |
| Emerging Markets | 26% | China, Taiwan, India, Brazil |
| North America | 6% | Canada |
| Middle East | 2% | Israel, UAE |
VXUS Top Holdings
| Rank | Company | Country | Weight |
|---|---|---|---|
| 1 | Taiwan Semiconductor | Taiwan | 2.3% |
| 2 | Novo Nordisk | Denmark | 1.5% |
| 3 | ASML Holding | Netherlands | 1.4% |
| 4 | Samsung Electronics | South Korea | 1.3% |

VXUS Sector Breakdown
| Sector | VXUS Weight | vs VTI |
|---|---|---|
| Financials | 21.0% | +8.0% |
| Industrials | 14.5% | +5.5% |
| Technology | 13.0% | -17.5% |
| Consumer Discretionary | 11.5% | +1.0% |
| Healthcare | 10.0% | -2.5% |
| Consumer Staples | 8.5% | +3.0% |
| Materials | 7.0% | +5.0% |
| Energy | 5.5% | +1.5% |
| Communication | 5.0% | -3.5% |
| Utilities | 3.0% | +0.5% |
| Real Estate | 1.0% | -1.0% |
Key observation: VXUS has far less technology exposure and far more financials, industrials, and materials. It's a more "old economy" portfolio.
Correlation and Diversification
The main argument for owning international stocks is diversification. If U.S. and international stocks don't move in lockstep, combining them reduces portfolio volatility.
Historical Correlations (VTI vs VXUS)
| Time Period | Correlation | Interpretation |
|---|---|---|
| 1 Year | 0.82 | High correlation |
| 5 Years | 0.88 | Very high correlation |
| 10 Years | 0.85 | Very high correlation |
| 20 Years | 0.87 | Very high correlation |
Bad news: The correlation is pretty high. In a global crisis, both U.S. and international stocks tend to fall together. You won't get "uncorrelated" returns.
Good news: Correlation isn't perfect. There are periods where U.S. outperforms (like 2010-2020) and periods where international outperforms (like 2000-2010). Owning both smooths the ride somewhat.
Volatility Comparison
| Metric | VTI | VXUS | 60/40 VTI/VXUS |
|---|---|---|---|
| Standard Deviation (10yr) | 18.5% | 17.2% | 17.0% |
| Max Drawdown (10yr) | -34% | -33% | -32% |
| Sharpe Ratio (10yr) | 0.65 | 0.25 | 0.50 |
Historical Performance
This is where it gets contentious. U.S. stocks have crushed international stocks for the past 15 years.
Recent Performance (Annualized Returns)
| Period | VTI (US) | VXUS (Int'l) | Difference |
|---|---|---|---|
| 1 Year | 25.1% | 8.2% | US +16.9% |
| 3 Years | 9.8% | 2.1% | US +7.7% |
| 5 Years | 14.2% | 4.8% | US +9.4% |
| 10 Years | 12.4% | 4.6% | US +7.8% |
| 15 Years | 13.8% | 5.2% | US +8.6% |
The U.S. has dominated since the 2008 financial crisis. Investors who went 100% U.S. have been rewarded handsomely.
But Wait - Look at 2000-2010
| Period | US Stocks | Int'l Stocks | Difference |
|---|---|---|---|
| 2000-2010 | -0.95% annualized | +3.50% annualized | Int'l +4.45% |
| 2003 | +28.7% | +38.6% | Int'l +9.9% |
| 2004 | +10.9% | +20.2% | Int'l +9.3% |
| 2005 | +4.9% | +13.5% | Int'l +8.6% |
| 2006 | +15.8% | +26.3% | Int'l +10.5% |
| 2007 | +5.5% | +15.0% | Int'l +9.5% |
International stocks crushed U.S. stocks for most of the 2000s. If you retired in 2010 with 100% U.S. stocks, you had a "lost decade" - zero gains in 10 years while international investors prospered.
The Takeaway
Leadership rotates. The U.S. won't outperform forever, just as it didn't outperform during the 2000s. The question is whether you want to bet on one winner or own both.
Optimal Allocation Models
There's no single "right" answer, but here are common frameworks:
Common Allocation Models
| Model | US (VTI) | Int'l (VXUS) | Rationale |
|---|---|---|---|
| Global Market Cap | 60% | 40% | Own the world in proportion to its value |
| US-Tilted | 70% | 30% | Home country tilt + some diversification |
| US-Heavy | 80% | 20% | Strong US preference + token diversification |
| US-Only | 100% | 0% | Reject international diversification |
| Bogleheads Target Date | 60-70% | 30-40% | Vanguard Target Date fund allocation |
Arguments for Different Allocations
For 60/40 (Global Market Weight)
- This is the actual composition of global stock markets
- Maximum diversification across geographies
- No need to predict which region will outperform
- What Vanguard uses in their target-date funds
For 70/30 or 80/20 (US Tilt)
- U.S. has stronger shareholder protections
- U.S. companies are already global (50%+ of S&P 500 revenue is international)
- Avoids currency risk and foreign withholding taxes
- Simpler tax reporting (no foreign tax credits)
For 100% US
- U.S. has outperformed for 15 years
- U.S. companies dominate global technology
- Avoid underperforming international markets
- Simpler portfolio management
Simulation: Different Allocations (2010-2025)
| Allocation | Annualized Return | Volatility | $10K Grew To |
|---|---|---|---|
| 100% US (VTI) | 13.8% | 18.5% | $71,000 |
| 80% US / 20% Int'l | 12.1% | 17.2% | $56,000 |
| 70% US / 30% Int'l | 11.2% | 16.8% | $49,000 |
| 60% US / 40% Int'l | 10.3% | 16.5% | $43,000 |
In hindsight, 100% US was the winning strategy. But nobody knew this in 2010, and it might not be true for 2026-2040.
Home Country Bias Discussion
Home country bias is the tendency for investors to overweight their own country's stocks. Americans overweight U.S. stocks. Japanese overweight Japanese stocks. Everyone does it.
Why We Have Home Country Bias
- Familiarity: We know U.S. companies - Apple, Amazon, Google
- Recency bias: U.S. has outperformed recently, so we expect it to continue
- Simplicity: One fund (VTI) is easier than two (VTI + VXUS)
- Currency: We spend in dollars, so dollar-denominated assets feel safer
- Tax complexity: Foreign tax credits are annoying
Why Home Country Bias Can Be Dangerous
- Concentration risk: All eggs in one basket (one country)
- Mean reversion: Outperforming markets tend to underperform eventually
- Valuation: U.S. stocks are expensive (P/E ~24) vs international (P/E ~14)
- Japan example: Japanese investors in 1989 were 100% Japan... then lost 30 years
The Japan Cautionary Tale
In 1989, Japan was 45% of global stock market cap. Japanese investors were 100% invested in Japanese stocks. The Nikkei hit 38,957.
35 years later, the Nikkei is still below that level (adjusted for dividends, it's roughly even). Japanese investors who diversified globally did far better.
Could this happen to the U.S.? Probably not to the same extreme, but outperformance doesn't last forever.
The Bottom Line
There's no objectively "correct" U.S. vs international allocation. But here's a framework for deciding:
Choose 60/40 US/International If:
- You want to own the global market as it exists
- You believe in diversification across countries
- You're investing for 20+ years and don't want to predict winners
- You're comfortable with Vanguard's own target-date allocation
Choose 70/30 or 80/20 US Tilt If:
- You believe U.S. has structural advantages (innovation, rule of law)
- You want some diversification but prefer U.S. companies
- You want to minimize currency risk and tax complexity
- This is a reasonable middle ground most can live with
Choose 100% US If:
- You're fully convinced U.S. will continue to outperform
- You don't want to deal with foreign tax credits
- You believe U.S. multinational exposure is "international enough"
- But understand you're making a concentrated bet
My Recommendation
For most investors: 70% VTI / 30% VXUS is a reasonable allocation.
- It provides meaningful international diversification
- It maintains a home country tilt that's not unreasonable
- It's simple to maintain with two funds
- It's within the range of expert recommendations
What Matters Most
Whether you choose 60/40, 70/30, 80/20, or even 100/0, the most important thing is:
- Pick an allocation you can stick with for decades
- Don't change it based on recent performance
- Stay invested through market ups and downs
- Keep costs low - VTI and VXUS are both excellent
The difference between a 70/30 and 60/40 allocation is far less important than consistently investing and staying the course.
Additional Editorial Notes
When reading VTI vs VXUS 2026: US vs International Diversification, the practical question is not whether the theme sounds attractive. In Investment Basics, readers need to separate time horizon, tax treatment, liquidity, currency exposure, and downside tolerance. Topics connected with VTI, VXUS, International Investing, Diversification, Global Stocks can look simple in headlines, but the result often depends on several moving assumptions. This review adds a clearer framework for readers returning to the page later.
US vs international stock allocation. VTI and VXUS comparison, correlation benefits, and optimal portfolio mix. Still, a short description cannot cover the full decision process. The same yield can mean different things when currency conversion, account type, fees, and exit timing are included. A reader should first decide whether the money is short-term cash, medium-term savings, or long-term capital before drawing conclusions from market commentary.
How to Read This Page
| Lens | What to Check | Common Mistake |
|---|---|---|
| Time horizon | Separate near-term cash from long-term capital | Reacting to short-term moves with long-term money |
| Currency | Compare local-currency and home-currency outcomes | Treating currency gains as fundamental performance |
| Costs | Add fees, spreads, taxes, and fund expenses | Comparing only headline yields or returns |
| Liquidity | Check whether funds can be accessed when needed | Assuming normal-market conditions during stress |
VTI vs VXUS 2026: US vs International Diversification is most useful when treated as a decision framework, not a single answer. Before acting on any market view, define when the money will be used, what currency it will be spent in, and what condition would make the position too large.
- Cash buffer: keep essential spending separate from market exposure.
- Concentration: avoid stacking assets that all respond to the same factor.
- Review date: decide when rates, rules, fees, and risks will be checked again.
- Exit condition: write down what would justify reducing exposure.
