What is a collar on MBX?
A collar pairs long stock with a protective out-of-the-money put financed by a short out-of-the-money call, capping both tails of the position around the current spot.
Current MBX snapshot
As of May 15, 2026, spot at $32.59, ATM IV 108.70%, IV rank 10.28%, expected move 31.16%. The collar on MBX 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 collar structure on MBX specifically: IV regime affects collar pricing on both sides; compressed MBX IV at 108.70% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 31.16% (roughly $10.16 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 MBX expiries trade a higher absolute premium for lower per-day decay. Position sizing on MBX should anchor to the underlying notional of $32.59 per share and to the trader's directional view on MBX stock.
MBX collar setup
The MBX collar below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With MBX near $32.59, the first option leg uses a $34.22 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MBX 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 MBX shares for the stock leg in covered calls and collars).

MBX thesis for this collar
The market-implied 1-standard-deviation range for MBX extends from approximately $22.43 on the downside to $42.75 on the upside. A MBX collar hedges an existing long MBX position with a protective put while financing the put cost via a short call; when the premiums roughly offset, the collar acts as a near-zero-cost insurance band around the current spot. Current MBX IV rank near 10.28% 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 MBX at 108.70%. As a Healthcare name, MBX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MBX-specific events.
MBX collar positions are structurally neutral (protective); 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. MBX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MBX alongside the broader basket even when MBX-specific fundamentals are unchanged. Always rebuild the position from current MBX chain quotes before placing a trade.
