[Bloomberg Analyst: Crude Oil ETF USO Single-Day Trading Volume Surpasses $7.6 Billion, Setting a Historic Record] Deep Tide TechFlow reports that on March 9, Bloomberg ETF Senior Analyst Eric Balchunas posted on the X platform stating that the U.S. crude oil exchange-traded fund United States Oil Fund (USO) experienced exceptionally active trading today. As of 11:30 AM Eastern Time, its single-day trading volume had exceeded $7.6 billion, breaking its historical single-day trading record and far surpassing the trading levels during the periods of extreme oil market volatility in 2020 and 2022. Analysts believe that this surge in trading activity may stem from both professional traders and retail investors with high-risk appetites. USO is considered one of the stock-based assets most sensitive to oil price movements, and therefore often attracts significant short-term trading during periods of sharp oil price fluctuations. Eric Balchunas cautioned that since USO primarily tracks oil prices by rolling over crude oil futures contracts, long-term holdings may be subject to roll costs from futures contract rollover, and oil prices also face the risk of rapid pullbacks. Investors should be mindful of potential volatility.
