Current MASS snapshot

As of May 15, 2026, spot at $6.97, ATM IV 120.80%, IV rank 33.64%, expected move 34.63%. The bear put spread on MASS 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 bear put spread structure on MASS specifically: MASS IV at 120.80% 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 34.63% (roughly $2.41 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 MASS expiries trade a higher absolute premium for lower per-day decay. Position sizing on MASS should anchor to the underlying notional of $6.97 per share and to the trader's directional view on MASS stock.

MASS bear put spread setup

The MASS bear put 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 MASS near $6.97, the first option leg uses a $6.97 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MASS 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 MASS shares for the stock leg in covered calls and collars).

MASS thesis for this bear put spread

The market-implied 1-standard-deviation range for MASS extends from approximately $4.56 on the downside to $9.38 on the upside. A MASS bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on MASS, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current MASS IV rank near 33.64% is mid-range against its 1-year distribution, so the IV signal is neutral; the bear put spread thesis on MASS should anchor more to the directional view and the expected-move geometry. As a Healthcare name, MASS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MASS-specific events.

MASS bear put spread positions are structurally moderately 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. MASS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MASS alongside the broader basket even when MASS-specific fundamentals are unchanged. Long-premium structures like a bear put spread on MASS 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 MASS chain quotes before placing a trade.
