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 FLRN snapshot
As of May 15, 2026, spot at $30.80, ATM IV 31.10%, IV rank 41.11%, expected move 8.92%. The butterfly on FLRN 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 butterfly structure on FLRN specifically: FLRN IV at 31.10% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 8.92% (roughly $2.75 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 FLRN expiries trade a higher absolute premium for lower per-day decay. Position sizing on FLRN should anchor to the underlying notional of $30.80 per share and to the trader's directional view on FLRN etf.
FLRN butterfly setup
The FLRN 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 FLRN near $30.80, the first option leg uses a $29.26 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FLRN 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 FLRN shares for the stock leg in covered calls and collars).

FLRN thesis for this butterfly
The market-implied 1-standard-deviation range for FLRN extends from approximately $28.05 on the downside to $33.55 on the upside. A FLRN long call butterfly is a pinning play: it pays maximum at the middle strike if FLRN settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current FLRN IV rank near 41.11% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on FLRN should anchor more to the directional view and the expected-move geometry. As a Financial Services name, FLRN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FLRN-specific events.
FLRN 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. FLRN positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FLRN alongside the broader basket even when FLRN-specific fundamentals are unchanged. Always rebuild the position from current FLRN chain quotes before placing a trade.

With FLRN etf trading near $30.80, the strikes shown on this page are snapped to the nearest listed FLRN chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are FLRN butterfly max profit and max loss calculated?
