What is a collar on RNAC?
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 RNAC snapshot
As of June 30, 2026, spot at $10.26, ATM IV 115.50%, IV rank 21.29%, expected move 33.11%. The collar on RNAC 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 collar structure on RNAC specifically: IV regime affects collar pricing on both sides; compressed RNAC IV at 115.50% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 33.11% (roughly $3.40 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 RNAC expiries trade a higher absolute premium for lower per-day decay. Position sizing on RNAC should anchor to the underlying notional of $10.26 per share and to the trader's directional view on RNAC stock.
RNAC collar setup
The RNAC 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 RNAC near $10.26, the first option leg uses a $10.77 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed RNAC 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 RNAC shares for the stock leg in covered calls and collars).

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

| Buy 1 | Put | $9.75 | N/A |

RNAC thesis for this collar
The market-implied 1-standard-deviation range for RNAC extends from approximately $6.86 on the downside to $13.66 on the upside. A RNAC collar hedges an existing long RNAC 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 RNAC IV rank near 21.29% 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 RNAC at 115.50%. As a Healthcare name, RNAC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to RNAC-specific events.
RNAC 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. RNAC positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move RNAC alongside the broader basket even when RNAC-specific fundamentals are unchanged. Always rebuild the position from current RNAC chain quotes before placing a trade.
