How each insider's company stock moved after they traded it, against the S&P 500. A ranking of its own, never mixed with the members'.
Each figure is how a stock moved after an insider traded it, against the S&P 500 (SPY) over the same trading days — the stock's move, not the insider's profit. Insiders trade their own company under plans and blackout windows it sets; a strong record is not evidence of anything.
One decision is one Form 4's buys or sells of one stock by its primary reporting owner (a joint filing is one decision), dated by its earliest trade. Scores are shrunk toward zero for small samples; an insider is ranked once they have 8 matured decisions over 3 filings, with a 90% interval and a luck check against other insiders' trades on the same dates. Only filings of $50k or more in one direction are stored, so small trades are not in it.
The insider track record is being computed: the pipeline measures every insider's trades against the S&P 500 after each run.
