The United States Oil Fund, LP (USO) added 0.33% on October 15, 2026, closing at $153.6. The modest daily gain came as the oil-tracking exchange-traded fund continued to build on a notable week of upward momentum.
Over the past seven days, USO has climbed 6.71%, reflecting a sustained stretch of buying pressure in oil markets. The weekly advance stands as the most significant move across the tracked timeframes.
Despite the recent strength, USO remains down 1.95% over the trailing 30-day period, indicating that the fund spent much of the prior month in a softer pricing environment before the latest rally took hold.
Market capitalization data for USO was not available at the time of publication. The fund tracks movements in oil futures prices and is widely used as a proxy for near-term crude oil market sentiment.
