Current CRBU snapshot
As of May 15, 2026, spot at $2.13, ATM IV 123.80%, IV rank 25.82%, expected move 35.49%. The covered call on CRBU 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 covered call structure on CRBU specifically: CRBU IV at 123.80% is on the cheap side of its 1-year range, which means a premium-selling CRBU covered call collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 35.49% (roughly $0.76 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 CRBU expiries trade a higher absolute premium for lower per-day decay. Position sizing on CRBU should anchor to the underlying notional of $2.13 per share and to the trader's directional view on CRBU stock.
CRBU covered call setup
The CRBU covered 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 CRBU near $2.13, the first option leg uses a $2.24 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CRBU 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 CRBU shares for the stock leg in covered calls and collars).

CRBU thesis for this covered call
The market-implied 1-standard-deviation range for CRBU extends from approximately $1.37 on the downside to $2.89 on the upside. A CRBU covered call collects premium on an existing long CRBU position, trading off upside above the short call strike for immediate income; the short strike selection should reflect the trader's view on whether CRBU will breach that level within the expiration window. Current CRBU IV rank near 25.82% 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 CRBU at 123.80%. As a Healthcare name, CRBU options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CRBU-specific events.
CRBU covered call positions are structurally neutral to slightly 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. CRBU positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CRBU alongside the broader basket even when CRBU-specific fundamentals are unchanged. Short-premium structures like a covered call on CRBU carry tail risk when realized volatility exceeds the implied move; review historical CRBU earnings reactions and macro stress periods before sizing. Always rebuild the position from current CRBU chain quotes before placing a trade.
