The United States Oil Fund, LP (USO) closed at $166.23 on October 27, 2026, falling 1.95% over the prior 24 hours. The single-session decline interrupted what has otherwise been a sustained period of upward momentum for the oil-tracking exchange-traded fund.
Over the past seven days, USO has gained 3.33%, reflecting a broader short-term trend that stands in contrast to Tuesday's pullback. The 30-day performance tells an even more pronounced story, with the fund up 12.05% over that stretch, marking a substantial run for investors tracking crude oil prices through the vehicle.
No market capitalization figure was available for USO as of the reporting date. The fund is structured as a limited partnership and is designed to reflect the daily price movements of West Texas Intermediate crude oil futures.
The one-day dip comes amid the fund's otherwise strong recent trajectory, with the 30-day advance of 12.05% remaining one of the more notable moves across the broader ETF landscape in that period.
