VOO Investors Should Know: Why International ETFs Outperformed in 2026

VOO is down 3.54% year-to-date in Q1 2026 after gaining 29% in 2025. International ETFs like VXUS returned 39.91% over the past year.

International ETFs offer diversification benefits from a weaker dollar and reduced exposure to the volatile U.S. tech sector. Japan's new Prime Minister, Sanae Takaichi, has implemented economic reforms boosting global market performance.

VOO has a 0.03% expense ratio and provides broad exposure to large U.S. companies. It is ideal for investors bullish on the U.S. economy and tech sector, but its heavy weighting in megacap tech creates concentration risk.

In Q1 2026, the Vanguard S&P 500 ETF (VOO) has lagged behind the broader market gains it delivered in 2025. The fund, which is down 3.54% year-to-date, is facing stiff competition from international ETFs like Vanguard Total International Stock Index Fund (VXUS), which returned 39.91% in the past year. This performance gap is not just a short-term anomaly but a reflection of broader market dynamics, particularly a weaker U.S. dollar, global economic reforms, and reduced exposure to the U.S. tech sector according to market analysis.

Why VOO's Performance Dropped in Q1 2026

VOO's pullback in early 2026 has been notable, especially after a strong 2025 where it gained 29%. This drop has caught the attention of investors who previously relied on VOO as a cornerstone of their U.S. market exposure. The S&P 500, which VOO tracks, is heavily concentrated in the technology sector, particularly the so-called "Magnificent Seven" companies like Apple, Microsoft, and Nvidia. These companies have driven much of the market's gains, but they also expose the index—and by extension VOO—to volatility according to market analysis.

The concentration of the S&P 500 in tech has led to overexposure to a narrow segment of the market. In contrast, international markets offer a more balanced diversification of sectors and geographies, which can provide cushioning during periods of U.S. tech sector volatility. As the dollar weakened, international stocks became more competitive in global portfolios, offering higher returns and lower risk according to market analysis.

Why Are International ETFs Outperforming VOO in 2026?

One key reason international ETFs have outperformed VOO in 2026 is the global diversification they offer. These ETFs reduce reliance on the U.S. market and its current overexposure to the technology sector. For instance, Japan's new Prime Minister, Sanae Takaichi, has introduced a series of economic reforms dubbed "Sanaenomics," including expansive fiscal policy, strategic investments in technology and defense, and wage increases to combat inflation. Her policies have bolstered investor confidence in Japanese equities, contributing to the outperformance of global ETFs according to market analysis.

Additionally, the U.S. dollar's weakness has made international assets more attractive. A weaker dollar means U.S. investors can purchase more foreign stocks with their dollars, potentially boosting returns. For investors seeking to hedge against U.S. market risks, international ETFs offer an effective diversification strategy. They also provide exposure to emerging markets and economic reforms that can yield strong returns in a shifting global landscape according to market analysis.

Should VOO Still Be a Core Holding in 2026?

Despite its current underperformance, VOO remains a compelling investment for investors bullish on the U.S. economy. With a low expense ratio of just 0.03%, it is one of the most cost-effective ways to gain exposure to large U.S. companies. VOO also benefits from the S&P 500's broad market representation, making it a reliable long-term holding for those who believe in the resilience of the U.S. economy according to investment analysis.

However, the fund's heavy concentration in the technology sector has created a unique set of risks. As the market shifts and diversifies in 2026, investors may want to consider alternatives like the Vanguard Total Stock Market ETF (VTI), which offers broader exposure to the entire U.S. stock market, including small- and mid-cap stocks. This broader diversification can help reduce the volatility associated with large-cap tech stocks and provide potential upside from other sectors according to market analysis.

Ultimately, while VOO remains a solid core holding for many portfolios, investors may benefit from balancing their exposure with international ETFs to diversify risk and capitalize on global opportunities. The key is to understand the trade-offs between geographic diversification and sector concentration and to adjust accordingly based on individual investment goals and market conditions according to market analysis.
