"" Investor demand for broad U.S. equity exposure continues to surge, with the Vanguard S&P 500 ETF (VOO) recently becoming the first exchange-traded fund to surpass $1 trillion in assets under management.

The milestone follows another massive daily inflow and reflects the resilience of investor appetite for large-cap U.S. stocks despite ongoing concerns surrounding tariffs, economic growth, and geopolitical tensions.

As one of the most widely held S&P 500 index funds, VOO’s performance has been heavily driven by gains among the market’s largest technology and AI-related companies.

Several of the ETF’s top holdings have posted strong year-to-date gains, led by semiconductor and mega-cap tech names that continue to dominate market leadership in 2026.

Broadcom (AVGO) currently leads VOO’s largest holdings by year-to-date performance, rising more than 39% as investor enthusiasm surrounding AI infrastructure and semiconductor demand remains strong.

NVIDIA (NVDA) follows with gains of nearly 20%, while Apple (AAPL), Alphabet (GOOG), and Amazon (AMZN) round out the top five positive performers among the fund’s major holdings.

The strong performance from large-cap technology stocks has helped fuel continued inflows into passive index products like VOO, reinforcing the market’s persistent “buy-the-dip” mentality even during periods of volatility.

Not all of the ETF’s largest holdings have participated equally in the rally, however. Several heavyweight names are currently trading lower for the year, including Microsoft (MSFT), Meta Platforms (META), Tesla (TSLA), and Berkshire Hathaway (BRK.A), all of which have posted negative year-to-date returns.

Top VOO holdings by year-to-date performance:

Broadcom (AVGO) - YTD performance: 39.14%,
NVIDIA (NVDA) - YTD performance: 19.47%
Apple (AAPL) - YTD performance: 15.94%
