Current TWST snapshot
As of June 30, 2026, spot at $100.66, ATM IV 81.30%, IV rank 32.91%, expected move 23.31%. The long call on TWST 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 17-day expiry.
Why this long call structure on TWST specifically: TWST IV at 81.30% 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 23.31% (roughly $23.46 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated TWST expiries trade a higher absolute premium for lower per-day decay. Position sizing on TWST should anchor to the underlying notional of $100.66 per share and to the trader's directional view on TWST stock.
TWST long call setup
The TWST 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 TWST near $100.66, the first option leg uses a $100.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TWST chain at a 17-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 TWST shares for the stock leg in covered calls and collars).

TWST thesis for this long call
The market-implied 1-standard-deviation range for TWST extends from approximately $77.20 on the downside to $124.12 on the upside. A TWST 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 TWST IV rank near 32.91% is mid-range against its 1-year distribution, so the IV signal is neutral; the long call thesis on TWST should anchor more to the directional view and the expected-move geometry. As a Healthcare name, TWST options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TWST-specific events.
TWST 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. TWST positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TWST alongside the broader basket even when TWST-specific fundamentals are unchanged. Long-premium structures like a long call on TWST 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 TWST chain quotes before placing a trade.
