Current CBLL snapshot
As of May 15, 2026, spot at $16.42, ATM IV 93.90%, IV rank 21.31%, expected move 26.92%. The long call on CBLL 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 long call structure on CBLL specifically: CBLL IV at 93.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a CBLL long call, with a market-implied 1-standard-deviation move of approximately 26.92% (roughly $4.42 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 CBLL expiries trade a higher absolute premium for lower per-day decay. Position sizing on CBLL should anchor to the underlying notional of $16.42 per share and to the trader's directional view on CBLL stock.
CBLL long call setup
The CBLL long call below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With CBLL near $16.42, the first option leg uses a $16.42 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CBLL 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 CBLL shares for the stock leg in covered calls and collars).

CBLL thesis for this long call
The market-implied 1-standard-deviation range for CBLL extends from approximately $12.00 on the downside to $20.84 on the upside. A CBLL long call expresses a directional view that the underlying closes above the strike plus premium at expiration, ideally with implied volatility holding or expanding to preserve extrinsic value through the hold period. Current CBLL IV rank near 21.31% 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 CBLL at 93.90%. As a Healthcare name, CBLL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CBLL-specific events.
CBLL long call positions are structurally bullish; 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. CBLL positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CBLL alongside the broader basket even when CBLL-specific fundamentals are unchanged. Long-premium structures like a long call on CBLL 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 CBLL chain quotes before placing a trade.
