Current MASI snapshot
As of May 15, 2026, spot at $178.50, ATM IV 156.40%, IV rank 37.21%, expected move 0.21%. The bull call spread on MASI below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 34-day expiry.
Why this bull call spread structure on MASI specifically: MASI IV at 156.40% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 0.21% (roughly $0.37 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated MASI expiries trade a higher absolute premium for lower per-day decay. Position sizing on MASI should anchor to the underlying notional of $178.50 per share and to the trader's directional view on MASI stock.
MASI bull call spread setup
The MASI bull call spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With MASI near $178.50, the first option leg uses a $180.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MASI chain at a 34-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 MASI shares for the stock leg in covered calls and collars).

MASI thesis for this bull call spread
The market-implied 1-standard-deviation range for MASI extends from approximately $178.13 on the downside to $178.87 on the upside. A MASI bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on MASI, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current MASI IV rank near 37.21% is mid-range against its 1-year distribution, so the IV signal is neutral; the bull call spread thesis on MASI should anchor more to the directional view and the expected-move geometry. As a Healthcare name, MASI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MASI-specific events.
MASI bull call spread positions are structurally moderately bullish; 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. MASI positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MASI alongside the broader basket even when MASI-specific fundamentals are unchanged. Long-premium structures like a bull call spread on MASI are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current MASI chain quotes before placing a trade.
