What you get from a run
A plain-language summary of the move, a stat row of the figures pulled from the price history,
the chart drawn from those same points, and the data source line so every number on this page is attributable.
Nothing is estimated or filled in β if the feed has no data for a symbol, the run says so instead.
Accepted symbols and ranges
Symbols are exchange tickers as the feed lists them (for example AAPL, MSFT, SPY).
Ranges use short forms: 5d, 1mo, 6mo, ytd, 1y, 5y, max. Longer ranges use weekly or monthly closes,
so short-lived swings inside a day will not appear on a 5y chart.
