Noteworthy Friday Option Activity: FHN, AA, LUNR

Alcoa (AA) saw unusually large options activity with 106,467 contracts traded (~10.6M underlying shares), equal to 176.2% of its one‑month ADV (6.0M shares); the $45 put expiring Dec 26, 2025 accounted for 18,582 contracts (~1.9M shares). Intuitive Machines (LUNR) recorded 87,077 options contracts (~8.7M shares), about 154.6% of its one‑month ADV (5.6M), led by 8,039 contracts in the $12.50 call expiring Jan 16, 2026 (~803,900 shares). These flows indicate concentrated directional/options positioning in both names and may presage elevated price sensitivity around the highlighted strikes and expiries.

Analysis

Market structure: The oversized option flows (AA: 106,467 contracts = ~10.6M shares, 176% of ADTV; AA $45 put Dec‑26‑2025 = ~1.9M shares ≈32% of ADTV; LUNR: 87,077 contracts = ~8.7M shares, 155% ADTV; LUNR $12.50 call Jan‑16‑2026 ≈804k shares) create asymmetric supply/demand for the underlying. Market‑makers selling these options will delta‑hedge—selling AA stock into weakness (amplifying downside) and buying LUNR into strength—so short‑term order flow can materially move prices independent of fundamentals.

Risk assessment: Tail risks include operational shocks (LUNR launch failure or AA plant outage), commodity shocks (aluminum price swing >10% in 30 days), or a large institutional hedge unwind that forces violent re‑hedging. Immediate (days) risk is gamma‑driven slippage; short‑term (weeks/months) is repricing as OI builds or unwinds; long‑term (quarters) fundamentals reassert unless capital raises/dilution occur. Hidden dependency: large put blocks may be hedges for long AA exposures, not pure shorts—watch changes in open interest and dealer inventory.

Trade implications: Tactical trades should front‑run delta flows, not fundamentals. For AA, downside asymmetry favors defined‑risk bearish structures into Dec‑2025 (put spreads) or small short equity positions sized to liquidity constraints; for LUNR, the concentrated long‑dated calls suggest momentum opportunities—use limited‑risk bull call spreads into Jan‑2026. Cross‑asset: monitor LME aluminum moves, as a >7–10% move will flip thesis and option IV.

Contrarian angles: Consensus treats heavy put flow on AA as pure bearishness; it may instead be institutional hedging—if open interest rises without price decline, the market‑maker long gamma exposure could reverse pressure. Similarly, LUNR call blocks can create short squeezes that fade when IV reverts. Historical parallel: 12+ month concentrated option blocks often lead to front‑loaded volatility then mean reversion; beware chasing one‑way moves without paying for time decay.

Key Decisions for Investors

• AA defined‑risk bearish: Buy Dec‑26‑2025 $45/$35 put spread (or similar 10‑point width) sized to ~1% of portfolio cost; enter immediately if the $45 put OI rises another 15% in 3 trading days or AA trades below its 50‑day MA with >2x ADTV. Take profit at 2x premium or if AA drops 15–25%; stop‑loss: close if AA rallies +8% from entry.
• LUNR asymmetric bull: Buy Jan‑16‑2026 $12.50/$20 call spread sized 0.5–1% of portfolio, target cost <$2.00; enter within 30 days provided implied vol ≤60%. Take profit if spread value doubles or underlying rises >40%; cut if price falls 30% or IV spikes >40% (indicative of capitulation).
