What is a butterfly on FBK?
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 FBK snapshot
As of May 15, 2026, spot at $51.43, ATM IV 38.80%, IV rank 29.76%, expected move 11.12%. The butterfly on FBK 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 FBK specifically: FBK IV at 38.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a FBK butterfly, with a market-implied 1-standard-deviation move of approximately 11.12% (roughly $5.72 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 FBK expiries trade a higher absolute premium for lower per-day decay. Position sizing on FBK should anchor to the underlying notional of $51.43 per share and to the trader's directional view on FBK stock.
FBK butterfly setup
The FBK 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 FBK near $51.43, the first option leg uses a $48.86 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FBK 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 FBK shares for the stock leg in covered calls and collars).

|---|---|---|---|

When traders use butterfly on FBK
Butterflies on FBK are pinning bets - traders use them when they expect FBK to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
FBK thesis for this butterfly
The market-implied 1-standard-deviation range for FBK extends from approximately $45.71 on the downside to $57.15 on the upside. A FBK long call butterfly is a pinning play: it pays maximum at the middle strike if FBK settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current FBK IV rank near 29.76% 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 FBK at 38.80%. As a Financial Services name, FBK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FBK-specific events.
FBK 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. FBK positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FBK alongside the broader basket even when FBK-specific fundamentals are unchanged. Always rebuild the position from current FBK chain quotes before placing a trade.
