What is a butterfly on FLNA?
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.
Current FLNA snapshot
As of May 15, 2026, spot at $1.19, ATM IV 20.40%, expected move 5.85%. The butterfly on FLNA 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 245-day expiry.
Why this butterfly structure on FLNA specifically: IV rank is unavailable in the current snapshot, so regime-based timing for FLNA is inferred from ATM IV at 20.40% alone, with a market-implied 1-standard-deviation move of approximately 5.85% (roughly $0.07 on the underlying). The 245-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated FLNA expiries trade a higher absolute premium for lower per-day decay. Position sizing on FLNA should anchor to the underlying notional of $1.19 per share and to the trader's directional view on FLNA stock.
FLNA butterfly setup
The FLNA 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 FLNA near $1.19, the first option leg uses a $1.13 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FLNA chain at a 245-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 FLNA shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $1.13 | N/A |
| Sell 2 | Call | $1.19 | N/A |
| Buy 1 | Call | $1.25 | N/A |

FLNA thesis for this butterfly
The market-implied 1-standard-deviation range for FLNA extends from approximately $1.12 on the downside to $1.26 on the upside. A FLNA long call butterfly is a pinning play: it pays maximum at the middle strike if FLNA settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. As a Healthcare name, FLNA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FLNA-specific events.
FLNA 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. FLNA positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FLNA alongside the broader basket even when FLNA-specific fundamentals are unchanged. Always rebuild the position from current FLNA chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on FLNA?
- A butterfly on FLNA is the butterfly strategy applied to FLNA (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 FLNA stock trading near $1.19, the strikes shown on this page are snapped to the nearest listed FLNA chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are FLNA 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 FLNA butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 20.40%), 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 FLNA butterfly?
- The breakeven for the FLNA butterfly 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 FLNA market-implied 1-standard-deviation expected move is approximately 5.85%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
