What is a long put on BCAB?

Current BCAB snapshot

As of May 15, 2026, spot at $4.28, ATM IV 59.20%, IV rank 8.41%, expected move 16.97%. The long put on BCAB 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 63-day expiry.

Why this long put structure on BCAB specifically: BCAB IV at 59.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a BCAB long put, with a market-implied 1-standard-deviation move of approximately 16.97% (roughly $0.73 on the underlying). The 63-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated BCAB expiries trade a higher absolute premium for lower per-day decay. Position sizing on BCAB should anchor to the underlying notional of $4.28 per share and to the trader's directional view on BCAB stock.

BCAB long put setup

The BCAB long put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BCAB near $4.28, the first option leg uses a $4.28 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BCAB chain at a 63-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 BCAB shares for the stock leg in covered calls and collars).

BCAB thesis for this long put

The market-implied 1-standard-deviation range for BCAB extends from approximately $3.55 on the downside to $5.01 on the upside. A BCAB long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long BCAB position with one put per 100 shares held. Current BCAB IV rank near 8.41% 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 BCAB at 59.20%. As a Healthcare name, BCAB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BCAB-specific events.

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