Why insider buying matters

There is an old line on Wall Street: insiders sell for many reasons, but they buy for only one. A corporate officer or director might sell shares to diversify, pay taxes, or fund a purchase — but when they reach into their own pocket to buy more stock on the open market, it usually signals genuine confidence in the company's prospects.

This page filters out grants, option exercises, and tax events to show only true open-market purchases, then ranks them by size. A large buy from a CEO or CFO often carries more weight than a small one from a less senior insider, though cluster buying — several insiders purchasing around the same time — can be the most notable pattern of all.

Remember: insider buying is a data point, not a directive. Insiders can be wrong, and timing the market on any single signal is risky. Treat this as one input among many.

Frequently asked questions

What counts as an "open-market" insider buy?

An open-market purchase (SEC transaction code P) is when an insider buys their company's shares on a public exchange at the prevailing price, using their own money. This is distinct from receiving shares as compensation (a grant) or exercising stock options.

How far back does this ranking go?

The default window is the last 14 days, which keeps the list timely. Larger or older purchases drop off as new ones are filed.

Why might a well-known large buy be missing?

We parse a sample of the most recent purchase filings for speed. Extremely recent filings may take a few minutes to appear, and filings without a clear per-share price are harder to value. Always confirm against SEC EDGAR.
