The United States Oil Fund, LP (USO) closed at $153.85 on September 19, 2026, marking a decline of 0.95% over the prior 24-hour period. The modest daily pullback extended a mild weekly retreat, with the fund also down 0.67% over the past seven days.
Despite the near-term softness, USO has posted a substantial gain of 17.51% over the trailing 30-day period, reflecting a significant upswing in the underlying oil market during that window.
The divergence between the short-term and monthly performance figures highlights the volatile nature of commodity-linked funds, where daily price swings can contrast sharply with broader trends. USO is structured to track the price of light, sweet crude oil through futures contracts.
