USO Bull Call Spread — 2026-08-21

USO (United States Oil Fund) shows bullish unusual options activity: $1285K of buyer-initiated unusual call flow (100% call-dominant) detected across near-term expirations, with a peak vol/OI ratio of 33.7x on the 132 call. IV rank is 38 (moderate) — a bull call spread (132/133) trims theta/vega bleed versus a naked long. Buy the $132 / sell the $133 call bull call spread expiring 2026-08-21 (30 DTE) for a net debit of $0.53 ($53 per spread). Breakeven at $132.53; net delta 0.02.

Underlying: USO @ ~$128.40 | 2026-08-21 (30 DTE) | Net debit (entry): ~$53 per spread. Use limit orders at the mid or slightly worse.

MAX LOSS: Limited to the net debit ($53 per spread). Max gain is capped at the strike width minus the debit — a defined-risk, defined-reward trade. | IV RISK: IV rank is 38 — reasonable for a debit spread. | TIMING: 30 DTE — unusual flow is a near-term signal; act promptly or the setup may stale. Close or take profit before expiration week to avoid gamma risk. | SECTOR: USO is in Other — avoid concentration with other open Other positions. | EXECUTION: Use limit orders at mid or slightly worse on the spread (don't leg in). Verify the bid-ask before sending; do not chase with market orders. | EVENTS: Check for upcoming earnings, FDA decisions, or macro prints within the trade window that could cause outsized gap risk.
