What is a straddle on ANAB?

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.

Current ANAB snapshot

As of June 29, 2026, spot at $65.64, ATM IV 90.50%, IV rank 30.81%, expected move 25.95%. The straddle on ANAB 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 18-day expiry.

Why this straddle structure on ANAB specifically: ANAB IV at 90.50% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 25.95% (roughly $17.03 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated ANAB expiries trade a higher absolute premium for lower per-day decay. Position sizing on ANAB should anchor to the underlying notional of $65.64 per share and to the trader's directional view on ANAB stock.

ANAB straddle setup

The ANAB 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 ANAB near $65.64, the first option leg uses a $65.64 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ANAB chain at a 18-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 ANAB shares for the stock leg in covered calls and collars).

When traders use straddle on ANAB

ANAB thesis for this straddle

The market-implied 1-standard-deviation range for ANAB extends from approximately $48.61 on the downside to $82.67 on the upside. A ANAB 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 ANAB IV rank near 30.81% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on ANAB should anchor more to the directional view and the expected-move geometry. As a Healthcare name, ANAB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ANAB-specific events.

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