Current PRAX snapshot
As of May 14, 2026, spot at $346.70, ATM IV 69.20%, IV rank 4.30%, expected move 19.84%. The bull call spread 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 34-day expiry.
Why this bull call spread structure on PRAX specifically: PRAX IV at 69.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a PRAX bull call spread, with a market-implied 1-standard-deviation move of approximately 19.84% (roughly $68.78 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 PRAX expiries trade a higher absolute premium for lower per-day decay. Position sizing on PRAX should anchor to the underlying notional of $346.70 per share and to the trader's directional view on PRAX stock.
PRAX bull call spread setup
The PRAX bull call 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 PRAX near $346.70, the first option leg uses a $350.00 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 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 PRAX shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $350.00 | $24.30 |

PRAX thesis for this bull call spread
The market-implied 1-standard-deviation range for PRAX extends from approximately $277.92 on the downside to $415.48 on the upside. A PRAX bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on PRAX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current PRAX IV rank near 4.30% 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 69.20%. 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 bull call spread positions are structurally moderately bullish; 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 bull call spread 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.
