What is a bear put spread on RNA?

A bear put spread buys an at-the-money put and sells an out-of-the-money put at a lower strike for defined risk and defined reward bounded by the strike width.

RNA snapshot

As of August 14, 2026, spot at $13.14, ATM IV 18.60%, IV rank 10.50%, expected move 5.33%. The bear put spread on RNA below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 154-day expiry.

Why this bear put spread structure on RNA specifically: RNA IV at 18.60% is on the cheap side of its 1-year range, which favors premium-buying structures like a RNA bear put spread, with a market-implied 1-standard-deviation move of approximately 5.33% (roughly $0.70 on the underlying). The 154-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated RNA expiries trade a higher absolute premium for lower per-day decay. Position sizing on RNA should anchor to the underlying notional of $13.14 per share and to the trader's directional view on RNA stock.

RNA bear put spread setup

The RNA bear put spread below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With RNA at $13.14 on that close, the first option leg uses a $13.14 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed RNA chain at a 154-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 RNA shares for the stock leg in covered calls and collars).

When traders use bear put spread on RNA

Bear put spreads on RNA reduce the cost of a bearish RNA stock position by selling a lower-strike put; suited to moderate-decline theses where price reaches but does not vastly exceed the short strike.

RNA thesis for this bear put spread

The market-implied 1-standard-deviation range for RNA extends from approximately $12.44 on the downside to $13.84 on the upside. A RNA bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on RNA, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current RNA IV rank near 10.50% 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 RNA at 18.60%. As a Healthcare name, RNA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to RNA-specific events.

RNA bear put spread positions are structurally moderately bearish; 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. RNA positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move RNA alongside the broader basket even when RNA-specific fundamentals are unchanged. Long-premium structures like a bear put spread on RNA 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 RNA chain quotes before placing a trade.

Frequently asked questions

What is a bear put spread on RNA?
A bear put spread on RNA is the bear put spread strategy applied to RNA (stock). The strategy is structurally moderately bearish: A bear put spread buys an at-the-money put and sells an out-of-the-money put at a lower strike for defined risk and defined reward bounded by the strike width. With RNA stock at $13.14 on the August 14, 2026 close, the strikes shown on this page are snapped to the nearest listed RNA chain strike and the premiums come straight from that session's bid/ask midpoint.
How are RNA bear put spread max profit and max loss calculated?
Max profit equals strike width minus net debit times 100; max loss equals net debit times 100. Breakeven is long-put strike minus net debit. For the RNA bear put spread priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 18.60%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
What is the breakeven for a RNA bear put spread?
The breakeven for the RNA bear put spread priced on this page is no defined breakeven on the modeled curve at expiration, derived from the August 14, 2026 end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The RNA market-implied 1-standard-deviation expected move in the same options snapshot is approximately 5.33%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
When should you consider a bear put spread on RNA?
Bear put spreads on RNA reduce the cost of a bearish RNA stock position by selling a lower-strike put; suited to moderate-decline theses where price reaches but does not vastly exceed the short strike.
How does current RNA implied volatility affect this bear put spread?
RNA ATM IV is at 18.60% with IV rank near 10.50%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.
