How are BBIO 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 BBIO straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 45.90%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$727.79 per contract. Live intraday quotes will differ as the chain moves through the trading session.

Current BBIO snapshot

As of May 15, 2026, spot at $66.81, ATM IV 45.90%, IV rank 14.40%, expected move 13.16%. The straddle on BBIO 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 34-day expiry.

Why this straddle structure on BBIO specifically: BBIO IV at 45.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a BBIO straddle, with a market-implied 1-standard-deviation move of approximately 13.16% (roughly $8.79 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated BBIO expiries trade a higher absolute premium for lower per-day decay. Position sizing on BBIO should anchor to the underlying notional of $66.81 per share and to the trader's directional view on BBIO stock.

BBIO straddle setup

The BBIO 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 BBIO near $66.81, the first option leg uses a $67.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BBIO chain at a 34-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 BBIO shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$67.50	$3.55
Buy 1	Put	$67.50	$4.05

When traders use straddle on BBIO

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

BBIO thesis for this straddle

The market-implied 1-standard-deviation range for BBIO extends from approximately $58.02 on the downside to $75.60 on the upside. A BBIO 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 BBIO IV rank near 14.40% 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 BBIO at 45.90%. As a Healthcare name, BBIO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BBIO-specific events.

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