What is a straddle on RNAC?
A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.
Current RNAC snapshot
As of June 29, 2026, spot at $9.50, ATM IV 104.30%, IV rank 18.84%, expected move 29.90%. The straddle 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 18-day expiry.
Why this straddle structure on RNAC specifically: RNAC IV at 104.30% is on the cheap side of its 1-year range, which favors premium-buying structures like a RNAC straddle, with a market-implied 1-standard-deviation move of approximately 29.90% (roughly $2.84 on the underlying). The 18-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 $9.50 per share and to the trader's directional view on RNAC stock.
RNAC straddle setup
The RNAC straddle 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 $9.50, the first option leg uses a $9.50 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 18-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).
| Action | Type | Strike / Basis | Premium (est) |

| Buy 1 | Put | $9.50 | N/A |

When traders use straddle on RNAC
Straddles on RNAC are pure-volatility plays that profit from large moves in either direction; traders typically buy RNAC straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
RNAC thesis for this straddle
The market-implied 1-standard-deviation range for RNAC extends from approximately $6.66 on the downside to $12.34 on the upside. A RNAC long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current RNAC IV rank near 18.84% 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 104.30%. 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 straddle positions are structurally neutral / high-volatility (long premium); 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.
Frequently asked questions
- What is a straddle on RNAC?

With RNAC stock trading near $9.50, the strikes shown on this page are snapped to the nearest listed RNAC chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are RNAC straddle max profit and max loss calculated?

- The breakeven for the RNAC straddle priced on this page is no defined breakeven on the modeled curve at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current RNAC market-implied 1-standard-deviation expected move is approximately 29.90%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
