BC (Brunswick Corporation) trades in the Consumer Cyclical sector, specifically Auto - Recreational Vehicles, with a market capitalization of approximately $5.22B, a beta of 1.34 versus the broader market, a 52-week range of 58.56-90.25, average daily share volume of 699K, a public-listing history dating back to 1981, approximately 14K full-time employees. These structural characteristics shape how BC stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 1.34 indicates BC has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position. BC pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a butterfly on BC?
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.
BC snapshot
As of August 14, 2026, spot at $82.41, ATM IV 38.70%, IV rank 4.74%, expected move 11.09%. The butterfly on BC 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 BC specifically: BC IV at 38.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a BC butterfly, with a market-implied 1-standard-deviation move of approximately 11.09% (roughly $9.14 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 BC expiries trade a higher absolute premium for lower per-day decay. Position sizing on BC should anchor to the underlying notional of $82.41 per share and to the trader's directional view on BC stock.
BC butterfly setup
The BC 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 BC at $82.41 on that close, the first option leg uses a $78.29 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BC 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 BC shares for the stock leg in covered calls and collars).

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

| Buy 1 | Call | $86.53 | N/A |

When traders use butterfly on BC
Butterflies on BC are pinning bets - traders use them when they expect BC 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.
BC thesis for this butterfly
The market-implied 1-standard-deviation range for BC extends from approximately $73.27 on the downside to $91.55 on the upside. A BC long call butterfly is a pinning play: it pays maximum at the middle strike if BC settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current BC IV rank near 4.74% 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 BC at 38.70%. As a Consumer Cyclical name, BC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BC-specific events.
BC 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. BC positions also carry Consumer Cyclical sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BC alongside the broader basket even when BC-specific fundamentals are unchanged. Always rebuild the position from current BC chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on BC?
- A butterfly on BC is the butterfly strategy applied to BC (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 BC stock at $82.41 on the most recent close, the strikes shown on this page are snapped to the nearest listed BC chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are BC 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. For the BC butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 38.70%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a BC butterfly?
- The breakeven for the BC butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from the end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The BC market-implied 1-standard-deviation expected move in the same options snapshot is approximately 11.09%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a butterfly on BC?
- Butterflies on BC are pinning bets - traders use them when they expect BC 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.
- How does current BC implied volatility affect this butterfly?
- BC ATM IV is at 38.70% with IV rank near 4.74%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.
