Current PROK snapshot
As of May 14, 2026, spot at $1.70, ATM IV 170.80%, IV rank 33.67%, expected move 48.97%. The bull call spread on PROK 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 bull call spread structure on PROK specifically: PROK IV at 170.80% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 48.97% (roughly $0.83 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 PROK expiries trade a higher absolute premium for lower per-day decay. Position sizing on PROK should anchor to the underlying notional of $1.70 per share and to the trader's directional view on PROK stock.
PROK bull call spread setup
The PROK 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 PROK near $1.70, the first option leg uses a $1.70 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed PROK 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 PROK shares for the stock leg in covered calls and collars).

PROK thesis for this bull call spread
The market-implied 1-standard-deviation range for PROK extends from approximately $0.87 on the downside to $2.53 on the upside. A PROK bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on PROK, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current PROK IV rank near 33.67% is mid-range against its 1-year distribution, so the IV signal is neutral; the bull call spread thesis on PROK should anchor more to the directional view and the expected-move geometry. As a Healthcare name, PROK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to PROK-specific events.
PROK 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. PROK positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move PROK alongside the broader basket even when PROK-specific fundamentals are unchanged. Long-premium structures like a bull call spread on PROK 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 PROK chain quotes before placing a trade.
