What is a collar on PROK?
A collar pairs long stock with a protective out-of-the-money put financed by a short out-of-the-money call, capping both tails of the position around the current spot.
Current PROK snapshot
As of June 26, 2026, spot at $1.77, ATM IV 205.90%, IV rank 41.65%, expected move 59.03%. The collar 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 21-day expiry.
Why this collar structure on PROK specifically: IV regime affects collar pricing on both sides; mid-range PROK IV at 205.90% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 59.03% (roughly $1.04 on the underlying). The 21-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 $1.77 per share and to the trader's directional view on PROK stock.
PROK collar setup
The PROK collar 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 $1.77, the first option leg uses a $1.86 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 21-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).

|---|---|---|---|

| Buy 1 | Put | $1.68 | N/A |

PROK thesis for this collar
The market-implied 1-standard-deviation range for PROK extends from approximately $0.73 on the downside to $2.81 on the upside. A PROK collar hedges an existing long PROK position with a protective put while financing the put cost via a short call; when the premiums roughly offset, the collar acts as a near-zero-cost insurance band around the current spot. Current PROK IV rank near 41.65% is mid-range against its 1-year distribution, so the IV signal is neutral; the collar 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 collar positions are structurally neutral (protective); 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. Always rebuild the position from current PROK chain quotes before placing a trade.
