Current PRAX snapshot
As of June 26, 2026, spot at $317.58, ATM IV 56.80%, IV rank 3.17%, expected move 16.28%. The long put on PRAX 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 PRAX specifically: PRAX IV at 56.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a PRAX long put, with a market-implied 1-standard-deviation move of approximately 16.28% (roughly $51.72 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 PRAX expiries trade a higher absolute premium for lower per-day decay. Position sizing on PRAX should anchor to the underlying notional of $317.58 per share and to the trader's directional view on PRAX stock.
PRAX long put setup
The PRAX 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 PRAX near $317.58, the first option leg uses a $320.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PRAX 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 PRAX shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |

PRAX thesis for this long put
The market-implied 1-standard-deviation range for PRAX extends from approximately $265.86 on the downside to $369.30 on the upside. A PRAX long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long PRAX position with one put per 100 shares held. Current PRAX IV rank near 3.17% 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 PRAX at 56.80%. As a Healthcare name, PRAX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PRAX-specific events.
PRAX 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. PRAX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PRAX alongside the broader basket even when PRAX-specific fundamentals are unchanged. Long-premium structures like a long put on PRAX 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 PRAX chain quotes before placing a trade.
