Interesting MCK Put And Call Options For March 13th

At MCK's current price of $835.92, the $830 put is bid at $24 — selling-to-open would commit purchase at $830 with an effective cost basis of $806 (before commissions), is ~1% OTM, and analytics put the odds of it expiring worthless at 58%, implying a 2.89% cash return (24.57% annualized YieldBoost). On the call side, a covered-call at the $850 strike is bid $25; selling it against shares bought at $835.92 yields 4.68% if called at the March 13 expiration, is ~2% OTM, has a 52% chance to expire worthless (2.99% boost, 25.41% annualized). Implied volatilities are ~29% (put) and 28% (call) versus a 12-month realized volatility of 23%, suggesting modest option-premium opportunities for income-focused strategies.

Analysis

Market structure: The immediate winners are option premium sellers and yield-seeking capital able to deploy cash-secured puts or covered calls on MCK (collecting ~ $24–25 per contract), while pure equity upside buyers lose optionality (selling capped upside of ~2% to strike). The modest OTM probabilities (put 58% OTM survival, call 52% OTM) and IV (28–29%) > realized vol (23%) indicate willing sellers of protection and a market pricing in modest near-term event risk into March 13 expiries. Cross-asset effects are limited; primary flow will be equity-delta hedging (small stock selling/buying around strikes) rather than bond/FX moves, though a volatility shock could widen credit spreads in healthcare paper.

Risk assessment: Tail risks include regulatory/drug-pricing intervention, big distribution contract loss, or a macro gap down; any of these could move MCK >10% intraday and blow through option short positions. Time horizons matter: days — theta decay benefits sellers; weeks/months — earnings, policy headlines and IV re-pricing; quarters/years — structural share gains or margin erosion from pricing pressure. Hidden dependencies: risk of early assignment, liquidity gaps in options, and concentrated option exposure forcing large capital commitment if puts are assigned; catalysts that would rapidly reverse the trade are earnings, DOJ/state investigations, or a sudden healthcare policy bill.

Trade implications: For conservative yield capture, establish a cash‑secured sell-to-open MCK 830 put expiring Mar 13 (collect $24 → effective basis $806) sized 1–3% notional, with a hard stop: buy protection or close if MCK < $760 or IV > 35%. If already long MCK at ~$835.92, sell-to-open the Mar13 850 covered call (collect $25) to lock ~4.68% to expiry; plan to roll up only if price > $860 or IV collapses. Prefer defined-risk option structures over naked shorts: instead of naked put, consider selling 830/770 put spread to cap max loss and keep most of premium (target net credit ≥$18). Avoid naked vega—IV > realized supports limited short‑vega, but only as spreads.

Contrarian angles: The consensus treats these as simple yield trades, but it underestimates correlation risk — a healthcare shock would simultaneously widen IV and gap equity, creating asymmetric losses for put sellers. The IV premium (~5–6ppt above realized) suggests sellers are being paid, but historical distributor moves around policy/earnings show rapid >15% moves; therefore premium may be insufficient for tail risk. Mispricing exists for defined-risk spread sellers who can collect most yield while capping loss; conversely, buying calls expecting large upside is likely underpriced only if you anticipate a specific catalyst within 30 days.

Key Decisions for Investors

• Sell-to-open cash‑secured MCK Mar13 830 puts (collect $24 → $806 effective basis) sized 1–3% of portfolio notional; close or buy protection if MCK < $760 or IV > 35%; use only if comfortable owning shares at $806.
• If long MCK (~$835.92), sell-to-open Mar13 850 covered calls (collect $25) to lock ~4.68% to expiry; plan to roll up or buy back if price > $860 or two trading days prior to any earnings/policy announcement.
• Prefer defined‑risk alternative: sell MCK Mar13 830/770 put spread to collect target net credit ≥ $18, capping max loss to preserve yield while limiting tail exposure; size 1–2% notional.
• Avoid naked short‑vega exposure; if taking volatility view, implement short calendar/iron‑condor structures sized small (≤1% notional) and monitor realized vol vs IV — close if IV–realized gap narrows below 2ppt or if stock gaps >6% intraday.
