How Scores Work

Every insider purchase gets a score out of 100, built from three things: how much they spent, what else was going on, and how recently they bought.

Three more things are measured and shown on each signal but left out of the score — your own history with that insider, what the recent headlines say, and how the stock is trading today. None of them is a fact about the purchase, and all of them change on their own. That is why a signal reads the same for everyone and does not drift over time.

How much money the insider put in. Scored on a curve from $50,000 up to $50 million. Past $50M it maxes out — buys that large are rare enough that separating them further tells you nothing.

How this insider’s earlier buys have done in your watchlist. Shown for context, not counted — it is measured from your trades, so it would be different for every user.

Who else was buying, and when. Other insiders in the same stock, the same insider buying repeatedly, and whether the purchase landed just before an earnings date. All of it is fixed by the filings, so none of it changes later. Adds up, capped at 20.

How recently they bought. Insider signals have a shelf life — last week means more than two years ago.

Keywords picked out of the stock's recent headlines, plus whether earnings fall in the next two weeks. Shown for context, not counted. We read the last few headlines, so a catalyst that shows today can be gone next week — that is a fact about the news cycle, not about the purchase.

How the stock is trading today, plus analyst sentiment. Shown for context, not counted — it describes today’s market, not the filing, so it would change the score hour to hour. Useful for timing an entry.
