Current BBNX snapshot
As of May 15, 2026, spot at $9.32, ATM IV 141.40%, expected move 40.54%. The bear put spread on BBNX 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 bear put spread structure on BBNX specifically: IV rank is unavailable in the current snapshot, so regime-based timing for BBNX is inferred from ATM IV at 141.40% alone, with a market-implied 1-standard-deviation move of approximately 40.54% (roughly $3.78 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 BBNX expiries trade a higher absolute premium for lower per-day decay. Position sizing on BBNX should anchor to the underlying notional of $9.32 per share and to the trader's directional view on BBNX stock.
BBNX bear put spread setup
The BBNX bear put spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BBNX near $9.32, the first option leg uses a $9.32 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BBNX 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 BBNX shares for the stock leg in covered calls and collars).

BBNX thesis for this bear put spread
The market-implied 1-standard-deviation range for BBNX extends from approximately $5.54 on the downside to $13.10 on the upside. A BBNX bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on BBNX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. As a Healthcare name, BBNX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BBNX-specific events.
BBNX bear put spread positions are structurally moderately bearish; 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. BBNX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BBNX alongside the broader basket even when BBNX-specific fundamentals are unchanged. Long-premium structures like a bear put spread on BBNX are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome.
