ONB (Old National Bancorp) trades in the Financial Services sector, specifically Banks - Regional, with a market capitalization of approximately $10.39B, a trailing P/E of 11.77, a beta of 0.84 versus the broader market, a 52-week range of 19.39-27.36, average daily share volume of 3.8M, a public-listing history dating back to 1984, approximately 5K full-time employees. These structural characteristics shape how ONB stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.84 places ONB roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 11.77 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. ONB pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a butterfly on ONB?
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.
ONB snapshot
As of August 14, 2026, spot at $27.23, ATM IV 24.40%, IV rank 2.07%, expected move 7.00%. The butterfly on ONB below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this butterfly structure on ONB specifically: ONB IV at 24.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a ONB butterfly, with a market-implied 1-standard-deviation move of approximately 7.00% (roughly $1.90 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated ONB expiries trade a higher absolute premium for lower per-day decay. Position sizing on ONB should anchor to the underlying notional of $27.23 per share and to the trader's directional view on ONB stock.
ONB butterfly setup
The ONB 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 ONB at $27.23 on that close, the first option leg uses a $25.87 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ONB chain at a 35-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 ONB shares for the stock leg in covered calls and collars).

When traders use butterfly on ONB
Butterflies on ONB are pinning bets - traders use them when they expect ONB 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.
ONB thesis for this butterfly
The market-implied 1-standard-deviation range for ONB extends from approximately $25.33 on the downside to $29.13 on the upside. A ONB long call butterfly is a pinning play: it pays maximum at the middle strike if ONB settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current ONB IV rank near 2.07% 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 ONB at 24.40%. As a Financial Services name, ONB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ONB-specific events.
ONB 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. ONB positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ONB alongside the broader basket even when ONB-specific fundamentals are unchanged. Always rebuild the position from current ONB chain quotes before placing a trade.
