U.S. stock markets fall as oil prices rise and Vanguard VOO hits $1T

U.S. stock markets experienced declines following the Labor Day weekend, with the Dow Jones Industrial Average falling 1.18%, the S&P 500 dropping 0.58%, and the Nasdaq Composite decreasing 0.32%. Market volatility was driven by rising oil prices, with Brent crude approaching $99 per barrel amid concerns over Middle East conflicts and potential disruptions to energy supplies. These rising energy costs have heightened inflation risks, complicating the Federal Reserve's upcoming decisions regarding interest rates.

In the exchange-traded fund (ETF) sector, Vanguard’s S&P 500 ETF (VOO) has surpassed $1 trillion in assets, becoming the largest ETF in the United States. Despite this milestone, VOO has not been the top performer in 2026; approximately one-third of Vanguard’s 116 U.S. ETFs have outperformed it. Leading the gains is the Vanguard Energy ETF (VDE), which has seen year-to-date returns of approximately 45.2%, significantly outpacing VOO’s 14% return.
