What is a straddle on ARCT?
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 ARCT snapshot
As of May 15, 2026, spot at $7.47, ATM IV 77.20%, IV rank 16.32%, expected move 22.13%. The straddle on ARCT 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 straddle structure on ARCT specifically: ARCT IV at 77.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a ARCT straddle, with a market-implied 1-standard-deviation move of approximately 22.13% (roughly $1.65 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 ARCT expiries trade a higher absolute premium for lower per-day decay. Position sizing on ARCT should anchor to the underlying notional of $7.47 per share and to the trader's directional view on ARCT stock.
ARCT straddle setup
The ARCT 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 ARCT near $7.47, the first option leg uses a $7.47 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ARCT 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 ARCT shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |

When traders use straddle on ARCT

ARCT thesis for this straddle
The market-implied 1-standard-deviation range for ARCT extends from approximately $5.82 on the downside to $9.12 on the upside. A ARCT 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 ARCT IV rank near 16.32% 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 ARCT at 77.20%. As a Healthcare name, ARCT options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ARCT-specific events.
ARCT 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. ARCT positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ARCT alongside the broader basket even when ARCT-specific fundamentals are unchanged. Always rebuild the position from current ARCT chain quotes before placing a trade.
