Current PRLD snapshot
As of May 14, 2026, spot at $4.48, ATM IV 143.00%, IV rank 28.66%, expected move 41.00%. The bear put spread on PRLD 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 bear put spread structure on PRLD specifically: PRLD IV at 143.00% is on the cheap side of its 1-year range, which favors premium-buying structures like a PRLD bear put spread, with a market-implied 1-standard-deviation move of approximately 41.00% (roughly $1.84 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 PRLD expiries trade a higher absolute premium for lower per-day decay. Position sizing on PRLD should anchor to the underlying notional of $4.48 per share and to the trader's directional view on PRLD stock.
PRLD bear put spread setup
The PRLD 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 PRLD near $4.48, the first option leg uses a $4.48 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PRLD 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 PRLD shares for the stock leg in covered calls and collars).

PRLD thesis for this bear put spread
The market-implied 1-standard-deviation range for PRLD extends from approximately $2.64 on the downside to $6.32 on the upside. A PRLD bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on PRLD, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current PRLD IV rank near 28.66% 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 PRLD at 143.00%. As a Healthcare name, PRLD options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PRLD-specific events.
PRLD 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. PRLD positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PRLD alongside the broader basket even when PRLD-specific fundamentals are unchanged. Long-premium structures like a bear put spread on PRLD 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 PRLD chain quotes before placing a trade.
