Prices are dividend- and split-adjusted, so “adj. close” is not necessarily what the stock printed that day. The horizon runs to the latest close, so rows with different trade dates are not comparable to each other — and none of these is the benchmark-relative, fixed-window alpha the leaderboard ranks on.

Disclosures are filed up to 45 days after a trade, so this is a record rather than a signal. Amounts are bracket midpoints. Symbols are recorded as they existed on the trade date and mapped forward where a company was renamed.
