Definitions

Prices use actual trading dates; operating data retains its reporting period ends. Different units and frequencies are shown in separate panels on a shared timeline. Records missing a date or value remain blank. Source-version dates may follow the initial disclosure and do not establish that the data was known at an earlier time. Relationship analysis requires at least 8 valid quarterly pairs; daily price observations are not counted as operating samples.

Methodology and controls

Each panel has its own value axis; dates and the cursor are synchronized. Operating data appear only on their observed dates; other dates are left blank. US daily prices are checked against the verified 1997–2027 trading calendar. A missing expected trading day breaks the line; weekends and recorded exchange holidays do not. Drag within the chart to zoom and move the range window below to pan. Quarterly values are not filled across other trading days.

X · Explanatory seriesY · Observed seriesPairing lagPrices are matched to each operating period; quarterly lags apply to two operating series.

One actual closing price per quarterPeriod-end comparison; this does not mean the data had been disclosed then.

Pairing methodology

Each operating quarter is matched to one actual closing price. Quarterly values are not repeated as daily observations.

Use the latest verified trading day on or before the reporting period end. If that session has no price, the value remains missing. A period-end comparison does not imply that the operating data was known to the market at that time.

Prices use the adjustment basis recorded by the source and exclude dividend reinvestment. A source’s statement is not independent verification. Correlation and regression describe only the selected historical sample.

Statistics use only the selected X and Y series after the chosen transformation within the current date range. At least 8 valid quarterly pairs are required. Quarters are matched by the calendar quarter containing the actual period end; fiscal quarter boundaries may differ across companies. Hiding a legend series does not change the sample or normalization base. Correlation and lagged regression describe the observed sample; they do not establish causation or predict investment returns.

Price changes after source publicationCross-check company operating data against actual trading sessionsVerified publication dates: 10

The baseline is the close of the first trading session after the verified source publication date, followed by observations 1, 5 and 20 trading sessions later. The source may be a revised document; its date is not verified as the first public release. These observations describe price changes, not announcement reactions, total returns or causal backtests.

Calculated metricPublic research%
