How are BOKF straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the BOKF straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 19.30%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$645.85 per contract.

Current BOKF snapshot

As of June 30, 2026, spot at $139.00, ATM IV 19.30%, IV rank 1.89%, expected move 5.53%. The straddle on BOKF 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 17-day expiry.

Why this straddle structure on BOKF specifically: BOKF IV at 19.30% is on the cheap side of its 1-year range, which favors premium-buying structures like a BOKF straddle, with a market-implied 1-standard-deviation move of approximately 5.53% (roughly $7.69 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated BOKF expiries trade a higher absolute premium for lower per-day decay. Position sizing on BOKF should anchor to the underlying notional of $139.00 per share and to the trader's directional view on BOKF stock.

BOKF straddle setup

The BOKF straddle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BOKF near $139.00, the first option leg uses a $140.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BOKF chain at a 17-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 BOKF shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$140.00	$4.13

When traders use straddle on BOKF

Straddles on BOKF are pure-volatility plays that profit from large moves in either direction; traders typically buy BOKF straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

BOKF thesis for this straddle

The market-implied 1-standard-deviation range for BOKF extends from approximately $131.31 on the downside to $146.69 on the upside. A BOKF long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current BOKF IV rank near 1.89% 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 BOKF at 19.30%. As a Financial Services name, BOKF options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BOKF-specific events.

BOKF straddle positions are structurally neutral / high-volatility (long premium); 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. BOKF positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BOKF alongside the broader basket even when BOKF-specific fundamentals are unchanged. Always rebuild the position from current BOKF chain quotes before placing a trade.
