MCK snapshot
As of August 14, 2026, spot at $868.58, ATM IV 26.30%, IV rank 17.32%, expected move 7.54%. The butterfly on MCK below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this butterfly structure on MCK specifically: MCK IV at 26.30% is on the cheap side of its 1-year range, which favors premium-buying structures like a MCK butterfly, with a market-implied 1-standard-deviation move of approximately 7.54% (roughly $65.49 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated MCK expiries trade a higher absolute premium for lower per-day decay. Position sizing on MCK should anchor to the underlying notional of $868.58 per share and to the trader's directional view on MCK stock.
MCK butterfly setup
The MCK butterfly below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With MCK at $868.58 on that close, the first option leg uses a $830.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MCK chain at a 35-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 MCK shares for the stock leg in covered calls and collars).

When traders use butterfly on MCK
Butterflies on MCK are pinning bets - traders use them when they expect MCK to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
MCK thesis for this butterfly
The market-implied 1-standard-deviation range for MCK extends from approximately $803.09 on the downside to $934.07 on the upside. A MCK long call butterfly is a pinning play: it pays maximum at the middle strike if MCK settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MCK IV rank near 17.32% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on MCK at 26.30%. As a Healthcare name, MCK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MCK-specific events.
MCK butterfly positions are structurally neutral / pin (limited-risk, limited-reward); the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. MCK positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MCK alongside the broader basket even when MCK-specific fundamentals are unchanged. Always rebuild the position from current MCK chain quotes before placing a trade.
