What is a long put on EBS?
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 EBS snapshot
As of June 30, 2026, spot at $8.46, ATM IV 66.10%, IV rank 4.25%, expected move 18.95%. The long put on EBS 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 17-day expiry.
Why this long put structure on EBS specifically: EBS IV at 66.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a EBS long put, with a market-implied 1-standard-deviation move of approximately 18.95% (roughly $1.60 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated EBS expiries trade a higher absolute premium for lower per-day decay. Position sizing on EBS should anchor to the underlying notional of $8.46 per share and to the trader's directional view on EBS stock.
EBS long put setup
The EBS 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 EBS near $8.46, the first option leg uses a $8.46 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed EBS chain at a 17-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 EBS shares for the stock leg in covered calls and collars).

EBS thesis for this long put
The market-implied 1-standard-deviation range for EBS extends from approximately $6.86 on the downside to $10.06 on the upside. A EBS long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long EBS position with one put per 100 shares held. Current EBS IV rank near 4.25% 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 EBS at 66.10%. As a Healthcare name, EBS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to EBS-specific events.
EBS 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. EBS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move EBS alongside the broader basket even when EBS-specific fundamentals are unchanged. Long-premium structures like a long put on EBS 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 EBS chain quotes before placing a trade.
