The United States Oil Fund, LP (USO) closed at $155.33 on September 18, 2026, declining 0.54% over the prior 24 hours as the energy-linked exchange-traded fund gave back modest ground after a prolonged rally.
The short-term retreat extends into the weekly timeframe as well, with USO down 1.91% over the past seven days. The back-to-back dips suggest some near-term selling pressure following an extended run higher.
Despite the recent softness, the fund's 30-day performance tells a markedly different story. USO has gained 18.86% over that stretch, reflecting a substantial upswing in the underlying crude oil market over the past month.
No market capitalization figure was available for the fund. The session's modest decline leaves USO consolidating within a range that, on a monthly basis, remains sharply elevated.
