How are AON straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the AON straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 25.50%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$1,955.48 per contract. Live intraday quotes will differ as the chain moves through the trading session.

Current AON snapshot

As of May 15, 2026, spot at $318.44, ATM IV 25.50%, IV rank 31.99%, expected move 7.31%. The straddle on AON 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 AON specifically: AON IV at 25.50% 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 7.31% (roughly $23.28 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 AON expiries trade a higher absolute premium for lower per-day decay. Position sizing on AON should anchor to the underlying notional of $318.44 per share and to the trader's directional view on AON stock.

AON straddle setup

The AON 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 AON near $318.44, the first option leg uses a $320.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed AON 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 AON shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$320.00	$9.90
Buy 1	Put	$320.00	$9.70

When traders use straddle on AON

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

AON thesis for this straddle

The market-implied 1-standard-deviation range for AON extends from approximately $295.16 on the downside to $341.72 on the upside. A AON 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 AON IV rank near 31.99% is mid-range against its 1-year distribution, so the IV signal is neutral; the straddle thesis on AON should anchor more to the directional view and the expected-move geometry. As a Financial Services name, AON options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to AON-specific events.

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