VOO Stock vs VT: Why Global ETFs Are Beating the S&P 500

Why VOO Stock Investors Are Rethinking Their Strategy in 2026

For the better part of a decade, the investment thesis was simple: buy VOO, hold it, and let the S&P 500 do the heavy lifting. Vanguard's S&P 500 ETF became the default choice for millions of investors seeking low-cost, passive exposure to America's largest companies. But 2026 is telling a different story — and VOO stockholders are paying attention.

The S&P 500 is down 3% year-to-date, while the Vanguard Total World Stock ETF (VT), which holds both US and international equities, is down less than 1%. That gap has sparked a broader conversation about whether the era of unquestioned US equity dominance is coming to an end, and whether VOO investors should be looking beyond American borders for better risk-adjusted returns.

VOO vs. VT: The Numbers That Are Turning Heads

The performance divergence between US-only and globally diversified index funds is no longer theoretical — it's showing up in real portfolio returns. Over the trailing one-year period, VT has returned 21% compared to 17.9% for SPY, the SPDR S&P 500 ETF that closely mirrors VOO's holdings. That 3.1 percentage point gap is significant for funds tracking broad market indices.

To be clear, the long-term track record still favors US equities. As 24/7 Wall St. recently reported, SPY has outperformed VT by 22 percentage points over the past decade, driven by historically low interest rates and dollar strength that turbocharged US equity returns. But markets are cyclical, and the conditions that powered that outperformance are shifting.

The key metrics at a glance:

• VT year-to-date performance (2026): Down less than 1%
• S&P 500 year-to-date performance (2026): Down 3%
• VT trailing one-year return: 21%
• SPY trailing one-year return: 17.9%
• VT total assets: $83.5 billion
• VT expense ratio: 0.06% (6 basis points)
• VT dividend yield: 1.74%

What's Behind the S&P 500's Underperformance?

Several factors are converging to weigh on US equities in early 2026 while international markets hold up comparatively well. Elevated valuations in US mega-cap tech stocks have left the S&P 500 vulnerable to even modest earnings disappointments. Meanwhile, European and Asian markets, which trade at lower multiples, have attracted capital from investors seeking better value.

The Reddit investing community has taken notice. A post titled "The Ex-U.S. Trade is Working" generated significant engagement, reflecting growing retail investor awareness that international diversification is actually delivering results after years of underperformance relative to the US market.

This isn't just a contrarian narrative — it's backed by capital flows. Investors who had been overweight US equities through funds like VOO and SPY are rebalancing toward globally diversified options, and VT's $83.5 billion in assets reflects sustained institutional and retail demand for broad international exposure.

Understanding VT: More Than Just "Not VOO"

One common misconception is that choosing VT over VOO means abandoning US stocks entirely. That's not the case. VT holds the entire investable global equity market, which means roughly 60% of the fund is still allocated to US companies. Its top holdings include familiar names like Apple, Nvidia, and Microsoft — the same mega-caps that anchor VOO.

The difference is what fills out the rest of the portfolio. VT extends into Canadian banks, European industrials, Latin American e-commerce companies, and Asian technology firms. This broader exposure is precisely what has cushioned VT against the concentrated drawdown in US equities this year.

From a cost perspective, there's virtually no penalty for going global. VT charges just 6 basis points annually — the same razor-thin expense ratio that made Vanguard's US index funds famous. And with a 1.74% dividend yield, VT offers a modest income stream that compares favorably to many US-focused alternatives.

The Currency Risk Factor VOO Investors Should Understand

Before rushing to swap VOO for VT, investors need to consider one important variable: currency risk. When you own international stocks through a US-listed ETF like VT, your returns are affected by movements in the US dollar relative to foreign currencies.

Dollar strength has historically been a headwind for international equity returns when measured in US dollar terms. If the dollar appreciates against the euro, yen, or emerging market currencies, the returns from international holdings within VT get reduced when converted back to dollars. This was a significant drag on international diversification during much of the 2010s.

Conversely, a weakening dollar amplifies international returns — and any sustained shift in dollar dynamics could further boost the case for global diversification. Investors should consider their view on the dollar's trajectory as part of the VOO-versus-VT decision.

Should You Sell VOO and Buy VT?

The answer depends on your time horizon and risk tolerance, but most financial advisors would caution against making dramatic portfolio shifts based on a few months of relative performance. Here are a few frameworks for thinking about the decision:

The case for staying with VOO: US companies still dominate global innovation, generate massive free cash flow, and benefit from the deepest and most liquid capital markets in the world. A 3% year-to-date decline is well within normal market fluctuations, and the decade-long track record of US outperformance reflects structural advantages that haven't disappeared overnight.

The case for adding VT: Concentration risk is real. The S&P 500 has become increasingly top-heavy, with a handful of mega-cap technology stocks driving an outsized share of returns. VT provides built-in geographic diversification at an identical cost, and the current rotation toward international equities could persist if US valuations continue to compress.

The case for owning both: Many investors hold VOO as a core US equity position and supplement it with dedicated international exposure. Others simply use VT as an all-in-one solution. There's no single right answer, but the 2026 data makes a compelling argument that some international allocation belongs in most portfolios.

Frequently Asked Questions

Is VOO still a good investment in 2026?

VOO remains one of the most cost-effective ways to invest in the S&P 500, and a 3% year-to-date decline is not unusual market volatility. However, the underperformance relative to globally diversified alternatives like VT has prompted many investors to reconsider whether a US-only allocation provides sufficient diversification. VOO is still a strong core holding — the question is whether it should be your only equity fund.

What is the difference between VOO and VT?

VOO tracks the S&P 500 — approximately 500 large US companies. VT tracks the FTSE Global All Cap Index, which includes thousands of stocks across developed and emerging markets worldwide, including the US. VT essentially contains VOO's holdings plus international stocks. Both charge extremely low expense ratios, making the choice primarily about geographic allocation rather than cost.

Why is the S&P 500 underperforming international stocks in 2026?

The S&P 500's heavy concentration in US mega-cap technology stocks has made it vulnerable as those valuations compress. Meanwhile, international markets — particularly in Europe and parts of Asia — have benefited from more attractive valuations, improving economic fundamentals, and capital rotation away from crowded US positions. Over the trailing year, VT has returned 21% versus 17.9% for SPY.

Does VT pay dividends?

Yes. VT currently offers a dividend yield of 1.74%, which is distributed quarterly. The yield reflects the blended dividend payments from thousands of companies across global markets, including higher-yielding international stocks that often pay more generous dividends than US growth companies.

What are the risks of switching from VOO to VT?

The primary risks include currency exposure, since roughly 40% of VT's holdings are denominated in foreign currencies, and the possibility that US equities resume their historical outperformance. Additionally, selling VOO in a taxable account could trigger capital gains taxes. Many advisors suggest gradually shifting allocation rather than making an abrupt switch.

The Bottom Line for VOO Stock Investors

The early months of 2026 have delivered a clear reminder: diversification works, even when it hasn't seemed necessary for years. VOO remains an excellent, low-cost vehicle for US equity exposure, but the assumption that US stocks will always lead global markets is being challenged by real performance data.

With VT down less than 1% while the S&P 500 sits 3% lower on the year, the argument for at least some international diversification has rarely been stronger. Whether you choose to complement VOO with international funds, switch to VT's all-in-one global approach, or stay the course with US equities, the most important step is making that decision deliberately — not by default.

The investors who will come out ahead are the ones who recognize that past performance, whether it favored the US or the rest of the world, is not a guarantee of future results. In an uncertain global environment, owning the whole market might just be the smartest bet of all.
