CMCSA Bull Call Spread — 2026-08-21

CMCSA (Comcast Corporation - Class A Common Stock) shows bullish unusual options activity: $92K of buyer-initiated unusual call flow (100% call-dominant) detected across near-term expirations, with a peak vol/OI ratio of 3.1x on the 23.5 call. IV rank is 61 (elevated) — too rich to buy a naked option into, so this is structured as a bull call spread (23.5/24) to cut vega and cost. Buy the $23.5 / sell the $24 call bull call spread expiring 2026-08-21 (25 DTE) for a net debit of $0.19 ($19 per spread). Breakeven at $23.69; net delta 0.09.

Underlying: CMCSA @ ~$23.21 | 2026-08-21 (25 DTE) | Net debit (entry): ~$19 per spread. Use limit orders at the mid or slightly worse.

MAX LOSS: Limited to the net debit ($19 per spread). Max gain is capped at the strike width minus the debit — a defined-risk, defined-reward trade. | IV RISK: IV rank is 61 — elevated IV inflates premiums; a vol crush could erode value even if direction is correct (the short leg offsets some of this vega). | TIMING: 25 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: CMCSA is in Communications — avoid concentration with other open Communications 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.
