Aecom (ACM) Max Pain Analysis

Max pain is the strike price where aggregate option buyer payout is minimized at expiration. It represents the price at which option writers retain the most premium.

Aecom (ACM) operates in the Industrials sector, specifically the Engineering & Construction industry, with a market capitalization near $9.12B, listed on NYSE, employing roughly 51,000 people, carrying a beta of 1.00 to the broader market. AECOM, together with its subsidiaries, provides professional infrastructure consulting services for governments, businesses, and organizations in the Americas, Europe, the Middle East, Africa, and the Asia Pacific.

Snapshot as of May 15, 2026.

Spot Price
$71.28
Max Pain Strike
$80.00
Total OI
13.0K

As of May 15, 2026, Aecom (ACM) max pain sits at $80.00, which is above the current spot price of $71.28 (12.2% away). Spot sits 12.2% above max pain - the gap is wide enough that the pinning effect alone is unlikely to close it; expect catalyst flow, positioning unwinds, or rebalancing to drive the actual price path before any expiration pull. ACM sits in the lower-price band (spot $71.28), where $0.50-$2.50 strike spacing makes pin-to-strike effects easy to spot but per-contract dollar gamma is smaller. Total open interest across the listed chain is comparatively thin (13.0K contracts), so single-strike pinning is less reliable than it is for high-OI names. ACM is currently in positive dealer gamma ($2.5K), the regime that mechanically reinforces pinning by inducing dealers to buy weakness and sell strength near heavy-OI strikes. Max pain identifies the strike at which the aggregate dollar value of all outstanding options contracts would expire with the least total intrinsic value, a gravitational reference rather than a price target.

ACM Strategy Implications at the Current Max Pain Level

With spot 12.2% from the $80.00 max-pain level and Aecom in a positive-gamma regime, where dealer hedging mechanically pulls spot toward heavy-OI strikes, strategy selection turns on cycle position and dealer positioning. Iron condors and credit spreads centered near the max-pain strike capture the typical end-of-cycle convergence when the regime supports pinning; ratio backspreads or directional debit structures fit names where catalyst flow is likely to overwhelm the hedging-driven pull. The gamma-exposure page shows the per-strike dealer book that determines whether hedging will reinforce or fight the pin.

Frequently asked ACM max pain analysis questions

What is the current ACM max pain strike?
As of May 15, 2026, Aecom (ACM) max pain sits at $80.00, which is 12.2% above the current spot price of $71.28. Max pain identifies the strike at which aggregate option-buyer payouts at expiration are minimized; it is a gravitational reference, not a price target. A 12.2% gap is wide enough that the pinning effect alone is unlikely to close it; expect catalyst flow, positioning unwinds, or rebalancing to drive the price path before any expiration pull.
Does ACM pin to its max pain strike at expiration?
ACM is currently in positive dealer gamma, the regime that mechanically reinforces pinning. Dealers hedging long-gamma books buy weakness and sell strength near high-OI strikes, which pulls spot toward those levels into expiration. Total open interest across ACM (13.0K contracts) is one input to how plausible a clean pin is - heavier total OI concentrated at fewer strikes raises the probability; thin OI spread across many strikes lowers it. Pinning is strongest in heavily-traded names with large open-interest concentrations at high-OI strikes during the final week of an OPEX cycle. Whether ACM actually pins on a given expiration depends on the OI distribution, the dealer-gamma sign, and the absence of catalyst-driven moves that overwhelm hedging-driven flow.
How is ACM max pain calculated?
Max pain is computed by summing the dollar value of all in-the-money options at each candidate settlement strike across listed expirations, then selecting the strike that minimizes total intrinsic-value payout to option buyers. The calculation uses the full open-interest distribution and weighs both calls and puts. ACM put/call OI ratio is 0.38 - call-heavy, which biases the max-pain calculation toward strikes above current spot when the call OI concentrates there.
