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.
Time rangeAMT · Closing price
Each panel has its own value axis; dates and the cursor are synchronized. Dense daily plots retain the first, last, highest and lowest observations in each pixel interval. The cursor, data table, CSV and statistics still use all original values. 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.
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.
Source-declared split-adjusted close; excludes dividend reinvestment · Through 2026-11-04
Actual trading dates and closing prices are retained. No observations are generated for market holidays or dates not included. Price changes exclude dividend reinvestment and do not represent total returns.
