Top insiders leaderboard
Recently active corporate insiders, ranked by how their open-market purchases have actually performed. Win rate is the share of an insider's buys now trading above the purchase price; returns are split- and dividend-adjusted.
Ranked by win rate, then average return, then number of scored trades. Only insiders with at least 3 priceable open-market buys appear. Updated periodically.
How the leaderboard works
We scan the most recent SEC Form 4 filings for open-market purchases, group them by the insider who made them, and then score each insider's buying history. For every purchase, we compare the adjusted closing price on the day of the trade to the latest close — so the return reflects what an investor would have made holding from that point, including the effect of stock splits and dividends.
An insider's win rate is the percentage of their scored buys currently in profit. We rank primarily by win rate, then by average return, and we require a minimum number of scored trades so the board isn't topped by someone who got lucky once. Each insider's profile breaks performance down further by 1-, 3-, 6-, and 12-month holding periods, separating good entry timing from simply riding a long winner.
Read this before you act on it. A strong track record is interesting context, not a signal to copy. Sample sizes here are small, past performance does not predict future results, and an insider's knowledge of their company says nothing about yours. Rankings shift as prices move and new filings arrive. InsiderSource is an information tool, not investment advice.
Frequently asked questions
What makes an insider rank highly here?
A high win rate on their open-market purchases — meaning most of the stock they bought with their own money is now worth more than they paid — followed by a strong average return. We only rank insiders with at least three priceable buys.
Are sales counted in the ranking?
No. We score only open-market purchases, because insiders sell for many routine reasons (taxes, diversification, liquidity) that say little about their view of the stock. Buying with their own money is the higher-signal action.
How often does the leaderboard update?
It refreshes periodically as new Form 4 filings arrive and as market prices change. Because scoring many insiders against live prices is intensive, results are cached for a few hours at a time.
Should I buy what these insiders buy?
No. This is context, not advice. Even insiders with great records can be wrong, the samples are small, and timing matters enormously. Do your own research and consider a licensed professional. InsiderSource is not investment advice.
