Current SMMT snapshot

As of June 30, 2026, spot at $14.51, ATM IV 95.37%, IV rank 37.05%, expected move 27.34%. The long put on SMMT 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 31-day expiry.

Why this long put structure on SMMT specifically: SMMT IV at 95.37% 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 27.34% (roughly $3.97 on the underlying). The 31-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SMMT expiries trade a higher absolute premium for lower per-day decay. Position sizing on SMMT should anchor to the underlying notional of $14.51 per share and to the trader's directional view on SMMT stock.

SMMT long put setup

The SMMT 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 SMMT near $14.51, the first option leg uses a $15.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SMMT chain at a 31-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 SMMT shares for the stock leg in covered calls and collars).

SMMT thesis for this long put

The market-implied 1-standard-deviation range for SMMT extends from approximately $10.54 on the downside to $18.48 on the upside. A SMMT long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long SMMT position with one put per 100 shares held. Current SMMT IV rank near 37.05% is mid-range against its 1-year distribution, so the IV signal is neutral; the long put thesis on SMMT should anchor more to the directional view and the expected-move geometry. As a Healthcare name, SMMT options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SMMT-specific events.

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