What is a straddle on CRBU?

A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.

CRBU snapshot

As of August 14, 2026, spot at $1.60, ATM IV 126.00%, IV rank 25.77%, expected move 36.12%. The straddle on CRBU below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.

Why this straddle structure on CRBU specifically: CRBU IV at 126.00% is on the cheap side of its 1-year range, which favors premium-buying structures like a CRBU straddle, with a market-implied 1-standard-deviation move of approximately 36.12% (roughly $0.58 on the underlying). The 35-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 $1.60 per share and to the trader's directional view on CRBU stock.

CRBU straddle setup

The CRBU 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 CRBU at $1.60 on that close, the first option leg uses a $1.60 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 35-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).

When traders use straddle on CRBU

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

CRBU thesis for this straddle

The market-implied 1-standard-deviation range for CRBU extends from approximately $1.02 on the downside to $2.18 on the upside. A CRBU 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 CRBU IV rank near 25.77% 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 126.00%. 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 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. 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. Always rebuild the position from current CRBU chain quotes before placing a trade.
