What is a butterfly on NRXS?
A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
NRXS snapshot
As of August 14, 2026, spot at $6.43, ATM IV 72.80%, expected move 20.87%. The butterfly on NRXS below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this butterfly structure on NRXS specifically: IV rank is unavailable in the current snapshot, so regime-based timing for NRXS is inferred from ATM IV at 72.80% alone, with a market-implied 1-standard-deviation move of approximately 20.87% (roughly $1.34 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated NRXS expiries trade a higher absolute premium for lower per-day decay. Position sizing on NRXS should anchor to the underlying notional of $6.43 per share and to the trader's directional view on NRXS stock.
NRXS butterfly setup
The NRXS butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With NRXS at $6.43 on that close, the first option leg uses a $6.11 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed NRXS chain at a 35-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 NRXS shares for the stock leg in covered calls and collars).

NRXS thesis for this butterfly
The market-implied 1-standard-deviation range for NRXS extends from approximately $5.09 on the downside to $7.77 on the upside. A NRXS long call butterfly is a pinning play: it pays maximum at the middle strike if NRXS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. As a Healthcare name, NRXS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to NRXS-specific events.
NRXS butterfly positions are structurally neutral / pin (limited-risk, limited-reward); 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. NRXS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move NRXS alongside the broader basket even when NRXS-specific fundamentals are unchanged. Always rebuild the position from current NRXS chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on NRXS?
- A butterfly on NRXS is the butterfly strategy applied to NRXS (stock). The strategy is structurally neutral / pin (limited-risk, limited-reward): A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration. With NRXS stock at $6.43 on the most recent close, the strikes shown on this page are snapped to the nearest listed NRXS chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are NRXS butterfly max profit and max loss calculated?
- Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the NRXS butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 72.80%), 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 NRXS butterfly?
- The breakeven for the NRXS butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from the end-of-day chain's premiums.
