ACGL (Arch Capital Group Ltd.) trades in the Financial Services sector, specifically Insurance - Diversified, with a market capitalization of approximately $32.61B, a trailing P/E of 6.89, a beta of 0.33 versus the broader market, a 52-week range of 82.45-103.39, average daily share volume of 2.0M, a public-listing history dating back to 1995, approximately 7K full-time employees. These structural characteristics shape how ACGL stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.33 indicates ACGL has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 6.89 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. ACGL pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a straddle on ACGL?
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 ACGL snapshot
As of May 15, 2026, spot at $94.09, ATM IV 22.50%, IV rank 34.74%, expected move 6.45%. The straddle on ACGL 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 ACGL specifically: ACGL IV at 22.50% 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 6.45% (roughly $6.07 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 ACGL expiries trade a higher absolute premium for lower per-day decay. Position sizing on ACGL should anchor to the underlying notional of $94.09 per share and to the trader's directional view on ACGL stock.
ACGL straddle setup
The ACGL 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 ACGL near $94.09, the first option leg uses a $94.09 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ACGL 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 ACGL shares for the stock leg in covered calls and collars).

When traders use straddle on ACGL

ACGL thesis for this straddle
The market-implied 1-standard-deviation range for ACGL extends from approximately $88.02 on the downside to $100.16 on the upside. A ACGL 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 ACGL IV rank near 34.74% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on ACGL should anchor more to the directional view and the expected-move geometry. As a Financial Services name, ACGL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ACGL-specific events.
ACGL 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. ACGL positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ACGL alongside the broader basket even when ACGL-specific fundamentals are unchanged. Always rebuild the position from current ACGL chain quotes before placing a trade.
