Derived after the close from the same dated options chain. Signed gamma exposure uses calls positive and puts negative; it is a model convention, not observed dealer inventory.
Advanced options analysis
Complete derived analysis from the dated chain, normalized where possible for comparison across tickers. Catalyst intensity measures unusual pricing and activity; it does not identify an event, predict direction, or establish that an investment is attractive.

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.
