Current RNAC snapshot
As of May 15, 2026, spot at $7.37, ATM IV 115.70%, IV rank 21.33%, expected move 33.17%. The cash-secured put 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 34-day expiry.
Why this cash-secured put structure on RNAC specifically: RNAC IV at 115.70% is on the cheap side of its 1-year range, which means a premium-selling RNAC cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 33.17% (roughly $2.44 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 RNAC expiries trade a higher absolute premium for lower per-day decay. Position sizing on RNAC should anchor to the underlying notional of $7.37 per share and to the trader's directional view on RNAC stock.
RNAC cash-secured put setup
The RNAC cash-secured 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 RNAC near $7.37, the first option leg uses a $7.00 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 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 RNAC shares for the stock leg in covered calls and collars).

RNAC thesis for this cash-secured put
The market-implied 1-standard-deviation range for RNAC extends from approximately $4.93 on the downside to $9.81 on the upside. A RNAC cash-secured put lets a trader earn premium while waiting to acquire RNAC at the strike price; the strategy is most attractive when the trader is comfortable holding the underlying at that level and IV is rich enough to compensate for the assignment risk. Current RNAC IV rank near 21.33% 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 115.70%. 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 cash-secured put positions are structurally neutral to slightly 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. 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. Short-premium structures like a cash-secured put on RNAC carry tail risk when realized volatility exceeds the implied move; review historical RNAC earnings reactions and macro stress periods before sizing. Always rebuild the position from current RNAC chain quotes before placing a trade.
