How are BEAM 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 BEAM butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 80.00%), the computed maximum profit is $72.96 per contract and the computed maximum loss is -$120.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a BEAM butterfly?

The breakeven for the BEAM butterfly priced on this page is roughly $34.20 and $35.80 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current BEAM market-implied 1-standard-deviation expected move is approximately 22.94%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current BEAM implied volatility affect this butterfly?

BEAM ATM IV is at 80.00% with IV rank near 39.90%, which is mid-range against its 1-year history. Strategy selection depends more on directional thesis and expected move than on a strong IV signal.

Current BEAM snapshot

As of June 30, 2026, spot at $34.75, ATM IV 80.00%, IV rank 39.90%, expected move 22.94%. The butterfly on BEAM 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 butterfly structure on BEAM specifically: BEAM IV at 80.00% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 22.94% (roughly $7.97 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 BEAM expiries trade a higher absolute premium for lower per-day decay. Position sizing on BEAM should anchor to the underlying notional of $34.75 per share and to the trader's directional view on BEAM stock.

BEAM butterfly setup

The BEAM 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 BEAM near $34.75, the first option leg uses a $33.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BEAM 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 BEAM shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$33.00	$3.78
Sell 2	Call	$35.00	$2.28
Buy 1	Call	$36.00	$1.98

When traders use butterfly on BEAM

Butterflies on BEAM are pinning bets - traders use them when they expect BEAM 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.

BEAM thesis for this butterfly

The market-implied 1-standard-deviation range for BEAM extends from approximately $26.78 on the downside to $42.72 on the upside. A BEAM long call butterfly is a pinning play: it pays maximum at the middle strike if BEAM settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current BEAM IV rank near 39.90% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on BEAM should anchor more to the directional view and the expected-move geometry. As a Healthcare name, BEAM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BEAM-specific events.

BEAM 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. BEAM positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BEAM alongside the broader basket even when BEAM-specific fundamentals are unchanged. Always rebuild the position from current BEAM chain quotes before placing a trade.
