IXUS vs. VXUS: Which International ETF Is the Better Buy for Global Diversification?

Vanguard Total International Stock ETF (NASDAQ:VXUS) and iShares Core MSCI Total International Stock ETF (NASDAQ:IXUS) both deliver broad international diversification, but VXUS covers more than 8,700 stocks and commands nearly ten times the assets under management (AUM), while IXUS costs a bit more yet yields slightly higher income.

Both funds are designed to provide exposure to developed and emerging non-U.S. equities, appealing to investors seeking global diversification beyond the U.S. stock market. This comparison looks at their costs, performance, sector makeup, and other key characteristics to help clarify which may be a better fit for investors.

Performance & risk comparison

What's inside

IXUS tracks a broad international index with more than 4,000 holdings. The fund is notably diversified, with its largest sector allocations in financial services (23%), technology (17%), and industrials (16%). Top positions include Taiwan Semiconductor Manufacturing(NYSE:TSM) at 3.79%, Samsung Electronics Ltd(FRA:SSUN) at 1.66%, and ASML Holding Nv(NASDAQ:ASML) at 1.34%.

VXUS offers similar sector exposures -- financial services, industrials, and technology are the top three -- and its three largest positions are the same as IXUS’ top three. But VXUS’ coverage is even broader, with the fund holding more than twice as many stocks as IXUS.

What this means for investors

For long-term investors looking to add international exposure to a U.S.-heavy portfolio, both IXUS and VXUS make a compelling case -- and frankly, the differences between them are fairly small.

If breadth matters to you, VXUS wins handily. With more than 8,700 holdings compared to IXUS's 4,155, VXUS casts a significantly wider net across global markets. That kind of diversification can be meaningful during volatile stretches, when markets in specific regions move independently of one another. VXUS's much larger asset base also speaks to institutional confidence -- for everyday investors, however, both funds are plenty liquid enough that you're unlikely to notice any difference in bid-ask spreads when buying or selling.

That said, IXUS is no slouch. Its slightly higher dividend yield could make a real difference for income-focused investors over time, especially when reinvested. And the expense ratio gap between the two -- while worth being aware of -- is slim enough that it shouldn't be a dealbreaker in either direction.

What's notable here is how closely aligned these two funds actually are. Their top holdings are nearly identical -- both led by Taiwan Semiconductor, Samsung, and ASML -- and their sector weightings mirror each other almost exactly. That similarity underscores a broader truth: for most retail investors, simply owning one broad international ETF and holding it consistently is likely to matter far more than which specific fund you choose. In a market environment where U.S. valuations remain elevated, having meaningful non-U.S. exposure through either of these vehicles is a reasonable, time-tested strategy for building a resilient long-term portfolio.
