The United States Oil Fund, LP (USO) closed at $156.18 on September 17, 2026, marking a decline of 3.53% from the prior session. The single-day pullback trimmed recent gains but left the fund well above levels seen earlier in the rolling periods tracked.
Despite Thursday's drop, USO posted a 7-day gain of 4.16%, reflecting broad strength in oil-linked assets over the near term. The 30-day performance tells a more striking story, with the fund advancing 19.88% over that stretch.
USO is structured as an exchange-traded fund designed to track movements in crude oil prices, and its price action tends to mirror swings in the underlying commodity market. The fund does not report a market capitalization figure in the data available for this session.
The combination of a sharp monthly rally and a modest single-session decline suggests the fund has experienced elevated volatility in recent weeks, with Thursday's move representing a partial consolidation of those outsized gains.
