CLS max pain and GEX snapshot
End-of-day snapshot for . Nearest-expiration max pain uses the expiry shown on its card; GEX uses the whole chain. Missing values are unavailable, not zero.
Prices are in US dollars per share. Net GEX is modeled dollar-delta change per $1 underlying move. Max pain minimizes aggregate intrinsic payout for that expiration; it is not a closing-price forecast. Signed GEX uses calls positive and puts negative, a model convention rather than observed dealer inventory. The flip is a confirmed zero crossing; walls locate side-specific concentrations, not guaranteed support or resistance.

Each expiration compares the last session before it, when it was the nearest expiration, with the close of the expiration session. Distances are percentages of that prior close. Underlying closes are not official option settlement values. The archive was reconstructed in September 2026, so it does not show what was published at the time. This is descriptive history, not a forecast. The site-wide 2025 max-pain study uses the same comparison on Thursday snapshots.

Returns are close-to-close after the labelled number of subsequent trading sessions. The confidence floor is the closest-to-zero bound of the order-statistic median interval; it is zero when that interval spans zero. Its coverage is nominally at least 90% under independent observations. Historical paths can overlap, so the interval and floor are descriptive uncertainty guides rather than formal coverage guarantees. Historical, not a forecast.
