Current PBYI snapshot
As of May 15, 2026, spot at $6.93, ATM IV 98.90%, IV rank 19.16%, expected move 28.35%. The bear put spread on PBYI 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 PBYI specifically: PBYI IV at 98.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a PBYI bear put spread, with a market-implied 1-standard-deviation move of approximately 28.35% (roughly $1.96 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 PBYI expiries trade a higher absolute premium for lower per-day decay. Position sizing on PBYI should anchor to the underlying notional of $6.93 per share and to the trader's directional view on PBYI stock.
PBYI bear put spread setup
The PBYI 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 PBYI near $6.93, the first option leg uses a $6.93 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PBYI 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 PBYI shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |

PBYI thesis for this bear put spread
The market-implied 1-standard-deviation range for PBYI extends from approximately $4.97 on the downside to $8.89 on the upside. A PBYI bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on PBYI, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current PBYI IV rank near 19.16% 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 PBYI at 98.90%. As a Healthcare name, PBYI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PBYI-specific events.
PBYI 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. PBYI positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PBYI alongside the broader basket even when PBYI-specific fundamentals are unchanged. Long-premium structures like a bear put spread on PBYI 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 PBYI chain quotes before placing a trade.
