The score weighs every filing on a stock together: what kind of filing it is, how large, how recent, and whether independent buyers agree. It ranks how strong the filing evidence is right now. It is not a probability that the stock will rise.
Signals come from SEC filings: Form 4 (insiders, filed within 2 business days), 13F (fund holdings, up to 45 days after quarter end) and Schedule 13D (5%+ activist stakes). This page reports what the filings show; it is not investment advice.
