Current PRME snapshot
As of May 14, 2026, spot at $3.13, ATM IV 102.40%, IV rank 21.97%, expected move 29.36%. The long put on PRME 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 35-day expiry.
Why this long put structure on PRME specifically: PRME IV at 102.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a PRME long put, with a market-implied 1-standard-deviation move of approximately 29.36% (roughly $0.92 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated PRME expiries trade a higher absolute premium for lower per-day decay. Position sizing on PRME should anchor to the underlying notional of $3.13 per share and to the trader's directional view on PRME stock.
PRME long put setup
The PRME 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 PRME near $3.13, the first option leg uses a $3.13 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PRME chain at a 35-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 PRME shares for the stock leg in covered calls and collars).

PRME thesis for this long put
The market-implied 1-standard-deviation range for PRME extends from approximately $2.21 on the downside to $4.05 on the upside. A PRME long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long PRME position with one put per 100 shares held. Current PRME IV rank near 21.97% 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 PRME at 102.40%. As a Healthcare name, PRME options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PRME-specific events.
PRME 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. PRME positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PRME alongside the broader basket even when PRME-specific fundamentals are unchanged. Long-premium structures like a long put on PRME 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 PRME chain quotes before placing a trade.
