Current OMER snapshot
As of May 15, 2026, spot at $12.27, ATM IV 89.50%, IV rank 20.78%, expected move 25.66%. The long put on OMER 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 OMER specifically: OMER IV at 89.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a OMER long put, with a market-implied 1-standard-deviation move of approximately 25.66% (roughly $3.15 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 OMER expiries trade a higher absolute premium for lower per-day decay. Position sizing on OMER should anchor to the underlying notional of $12.27 per share and to the trader's directional view on OMER stock.
OMER long put setup
The OMER 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 OMER near $12.27, the first option leg uses a $12.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed OMER 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 OMER shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |

OMER thesis for this long put
The market-implied 1-standard-deviation range for OMER extends from approximately $9.12 on the downside to $15.42 on the upside. A OMER long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long OMER position with one put per 100 shares held. Current OMER IV rank near 20.78% 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 OMER at 89.50%. As a Healthcare name, OMER options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to OMER-specific events.
OMER 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. OMER positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move OMER alongside the broader basket even when OMER-specific fundamentals are unchanged. Long-premium structures like a long put on OMER 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 OMER chain quotes before placing a trade.
