What is a long put on MRX?
A long put buys downside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes below the strike minus premium at expiration.
Current MRX snapshot
As of May 15, 2026, spot at $56.40, ATM IV 40.90%, IV rank 16.99%, expected move 11.73%. The long put on MRX 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 long put structure on MRX specifically: MRX IV at 40.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a MRX long put, with a market-implied 1-standard-deviation move of approximately 11.73% (roughly $6.61 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 MRX expiries trade a higher absolute premium for lower per-day decay. Position sizing on MRX should anchor to the underlying notional of $56.40 per share and to the trader's directional view on MRX stock.
MRX long put setup
The MRX long put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With MRX near $56.40, the first option leg uses a $56.40 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MRX 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 MRX shares for the stock leg in covered calls and collars).

MRX thesis for this long put
The market-implied 1-standard-deviation range for MRX extends from approximately $49.79 on the downside to $63.01 on the upside. A MRX long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long MRX position with one put per 100 shares held. Current MRX IV rank near 16.99% 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 MRX at 40.90%. As a Financial Services name, MRX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MRX-specific events.
MRX long put positions are structurally bearish; 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. MRX positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MRX alongside the broader basket even when MRX-specific fundamentals are unchanged. Long-premium structures like a long put on MRX 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 MRX chain quotes before placing a trade.
