What is a strangle on BANF?
A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.
Current BANF snapshot
As of May 15, 2026, spot at $107.11, ATM IV 29.00%, IV rank 4.50%, expected move 8.31%. The strangle on BANF 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 strangle structure on BANF specifically: BANF IV at 29.00% is on the cheap side of its 1-year range, which favors premium-buying structures like a BANF strangle, with a market-implied 1-standard-deviation move of approximately 8.31% (roughly $8.91 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 BANF expiries trade a higher absolute premium for lower per-day decay. Position sizing on BANF should anchor to the underlying notional of $107.11 per share and to the trader's directional view on BANF stock.
BANF strangle setup
The BANF strangle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BANF near $107.11, the first option leg uses a $110.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BANF 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 BANF shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $110.00 | $2.73 |
| Buy 1 | Put | $100.00 | $1.58 |

When traders use strangle on BANF
Strangles on BANF are the cheaper cousin of the straddle - traders use them when they want a large directional move but are willing to give up the inner-strike sensitivity in exchange for a lower up-front debit on the BANF chain.
BANF thesis for this strangle
The market-implied 1-standard-deviation range for BANF extends from approximately $98.20 on the downside to $116.02 on the upside. A BANF long strangle is the OTM cousin of the straddle: lower up-front cost but the underlying has to travel further past either OTM strike before the position turns profitable at expiration. Current BANF IV rank near 4.50% 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 BANF at 29.00%. As a Financial Services name, BANF options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BANF-specific events.
BANF strangle positions are structurally neutral / high-volatility (long premium, OTM); 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. BANF positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BANF alongside the broader basket even when BANF-specific fundamentals are unchanged. Always rebuild the position from current BANF chain quotes before placing a trade.
