The iShares MSCI ACWI ex U.S. ETF ( NASDAQ:ACWX ) has had an incredible 2025, despite excluding all US companies from its portfolio. After years of trailing domestic equities, international stocks have shown renewed strength in 2025 and ACWX is at the front of the pack.
The fund tracks the MSCI ACWI ex USA Index, providing exposure to roughly 2,000 stocks across developed and emerging markets outside the United States. Think Tencent in China, SAP in Germany, ASML in the Netherlands, Samsung in South Korea. No Apple, no Nvidia, no Microsoft. The portfolio splits roughly evenly between Europe and Asia, with smaller positions in Canada, Australia, and Latin America.
The Dollar Made the Difference
A key macro force behind international equity performance has been US dollar movement. When the dollar weakens, international stocks get a tailwind for US-based investors. Returns earned in euros, yen, or pounds translate into more dollars when converted back.
This infographic illustrates how the iShares MSCI ACWI ex U.S. ETF (ACWX) provides international diversification and currency exposure, outlining its benefits and drawbacks for investors.
Beyond currency, ACWX benefits from more balanced sector exposure. While the S&P 500 carries a 34% weight in technology stocks, ACWX spreads risk more evenly across financials, industrials, healthcare, and consumer sectors. That diversification provides different return characteristics than US-focused funds.
Looking ahead, watch the dollar. If it stabilizes or strengthens in 2026, that currency boost fades. The DXY index and Federal Reserve policy commentary are key signposts. A resurgent dollar could compress international equity returns for US investors, even if foreign stocks perform well in local currency terms.
What to Monitor Inside the Fund
ACWX holds $7.3 billion in assets with a 0.32% expense ratio and 2% dividend yield. The top 10 holdings represent just 12% of the portfolio, far lower than the S&P 500's 39% concentration in its top 10. That's a structural advantage in volatile markets, but it also means ACWX won't capture mega-cap rallies the way a US-focused fund might.
The fund's quarterly rebalancing can shift country and sector weights as index constituents change. Check the iShares website for updated holdings and geographic breakdowns, typically refreshed monthly. Pay attention to emerging market exposure, which sits around 25% of the portfolio. If growth in China, India, or Southeast Asia accelerates or stumbles, that will move the needle.
A Lower-Cost Alternative
Investors seeking similar exposure with tighter expenses should consider the iShares Core MSCI Total International Stock ETF ( NASDAQ:IXUS ). It tracks a nearly identical index with a 0.07% expense ratio, less than a quarter of ACWX's fee. IXUS also holds over $50 billion in assets, offering deeper liquidity and tighter bid-ask spreads. The performance difference is minimal, but over decades, that cost gap compounds.
The key question for 2026: whether the dollar stays weak and international valuations stay attractive enough to sustain the recent momentum in non-US equities.
