Noteworthy Thursday Option Activity: MCD, IRDM, AMAT

Iridium Communications (IRDM) saw 8,252 options contracts trade (~825,200 underlying shares), equal to ~46.6% of its one‑month average daily share volume (1.8M), led by 2,749 contracts in the $22.50 Feb 20, 2026 call (~274,900 shares). Applied Materials (AMAT) recorded 29,069 option contracts (~2.9M underlying shares), about 46.4% of its one‑month average daily volume (6.3M), with 2,178 contracts in the $330 Jan 23, 2026 call (~217,800 shares). The flows indicate concentrated call activity in both names and represent notable intraday positioning that may signal short‑term bullish speculation or hedging interest.

Analysis

Market structure: Heavy call flow in IRDM (2,749 Feb20 $22.50 calls ≈275k shares) and AMAT (2,178 Jan23 $330 calls ≈218k shares) equals ~46% of each name’s 1‑month ADV, signalling concentrated directional bets or hedges that force dealer delta-hedging. Short‑dated AMAT flow (expiry tomorrow) creates acute gamma risk and potential intraday squeezes; IRDM’s Feb 20 flow implies multi‑week dealer buying pressure if flow is directional.

Risk assessment: Immediate (hours–days) risk is a gamma squeeze in AMAT causing rapid repricing and elevated realized vol; short‑term (weeks) risk for IRDM is options-unwind after expiry or if trades are spreads not outright buys. Tail risks include mis‑classification of flow (complex spreads, block hedge) or counterparty failure; set thresholds: treat any single‑name options day >30% ADV as a catalyst requiring re‑hedge within 24h.

Trade implications: Direct actionable plays are asymmetric: for IRDM, prefer defined‑risk long-call debit spreads (Feb20 $22.5/$27.5) sized 1–2% portfolio to capture dealer buyflow; for AMAT avoid naked long calls into tomorrow and instead monetize premium with very short call spreads intraday (sell $330/$345 Jan23) or steer clear until post‑expiry volatility settles. Consider a pair: long AMAT equity vs short SOXX only after confirming idiosyncratic flow persists, size 1% and hold 1–4 weeks.

Contrarian angles: Consensus reads these as bullish; but large flow can be part of covered‑call issuance or protective call buys that expire worthless—if so, underlying will mean‑revert lower after dealers unwind. Historical parallels: short‑dated concentrated call buying ahead of catalysts often produces post‑expiry pullbacks of 5–15%; price action after AMAT’s close tomorrow is the decisive signal—if implied vol collapses >30% intraday, unwind bullish exposure.

Key Decisions for Investors

• Establish a defined‑risk long in IRDM: buy Feb 20, 2026 $22.50/$27.50 call debit spread, size 1–2% portfolio, max loss = premium paid; take profits if spread value rises 40–60% or IRDM > $27 within 2–5 weeks, stop at 30% loss.
• Do NOT buy AMAT Jan23 $330 calls into close; if extracting premium, sell an intraday Jan23 call spread (e.g., sell $330/$345 strike) sized <1% portfolio, and close before market close Jan 23 to avoid pin risk and overnight assignment.
• Initiate a relative‑value trade: small long AMAT equity (1% notional) vs short SOXX (1% notional) only after confirming >2 trading sessions of biased AMAT dealer buyflow, hold 1–4 weeks and hedge sector delta to isolate idiosyncratic move.
