Entry after publication
The clock starts at the first close following the filing, not on the transaction date. Between the two sits a legal delay during which nobody outside the company knew.
Insider track records
Ranked by median excess return over 63 trading sessions. Median, not average, because a single position that multiplied would otherwise carry an entire reputation.

Small samples are flagged
Under ten measured buys, the result is mostly noise. Those rows carry a warning rather than being quietly ranked alongside a hundred-trade history.
Survivorship cuts one way
Delisted and acquired companies lose their price history and drop out of the measurement. A delisting is rarely a success, so the numbers lean optimistic.
