What is a butterfly on EBC?
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.
EBC snapshot
As of August 14, 2026, spot at $23.61, ATM IV 22.40%, IV rank 2.50%, expected move 6.42%. The butterfly on EBC 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 EBC specifically: EBC IV at 22.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a EBC butterfly, with a market-implied 1-standard-deviation move of approximately 6.42% (roughly $1.52 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 EBC expiries trade a higher absolute premium for lower per-day decay. Position sizing on EBC should anchor to the underlying notional of $23.61 per share and to the trader's directional view on EBC stock.
EBC butterfly setup
The EBC 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 EBC at $23.61 on that close, the first option leg uses a $22.43 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed EBC 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 EBC shares for the stock leg in covered calls and collars).

When traders use butterfly on EBC
Butterflies on EBC are pinning bets - traders use them when they expect EBC 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.
EBC thesis for this butterfly
The market-implied 1-standard-deviation range for EBC extends from approximately $22.09 on the downside to $25.13 on the upside. A EBC long call butterfly is a pinning play: it pays maximum at the middle strike if EBC settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current EBC IV rank near 2.50% 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 EBC at 22.40%. As a Financial Services name, EBC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to EBC-specific events.
EBC 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. EBC positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move EBC alongside the broader basket even when EBC-specific fundamentals are unchanged. Always rebuild the position from current EBC chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on EBC?
- A butterfly on EBC is the butterfly strategy applied to EBC (stock). The strategy is structurally neutral / pin (limited-risk, limited-reward): 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. With EBC stock at $23.61 on the most recent close, the strikes shown on this page are snapped to the nearest listed EBC chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are EBC butterfly max profit and max loss calculated?
- Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit.

Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a EBC butterfly?
- The breakeven for the EBC butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from the end-of-day chain's premiums.
