Insider buying

When executives buy their own stock.

When a company’s executives, directors, or largest owners buy or sell its stock, US law requires them to report the trade publicly to the SEC on a document called Form 4. A CEO or CFO spending their own money on their own company’s shares is a signal worth watching: nobody knows the business better, and they only profit if the stock goes up.

Everything below comes from Form 4 filings our pipeline verified: open-market purchases of $50,000 or more that were not part of a pre-scheduled trading plan. The accumulation tracker looks back 90 days; the cluster and largest-buy sections cover the last 30.

Accumulation Tracker

The slower, stronger pattern: 3 or more verified buys at the same company across two weeks to three months, totaling $250K+. One insider buying again and again, or several buying staggered over weeks, is the configuration research grades highest, especially when they keep paying higher prices as the stock rises.

Cluster Buys

One insider buying can mean many things. Several insiders at the same company buying within days of each other is much harder to explain away. We call 3 or more insiders buying $2.0M+ combined within 7 days a cluster buy; companies where 2 or more insiders bought this month are listed too.

How InsiderWatch Uses This

Our pipeline reads every Form 4 as it reaches the SEC and only alerts on open-market purchases of $50,000 or more that were not made under a pre-scheduled 10b5-1 trading plan (trades set up months in advance say nothing about what the insider thinks today). Cluster buying, several insiders at one company buying within days, is one of the strongest signals we track. Alerts that pass those gates go to subscribers within minutes of the filing.

See the latest alerts we sent and the full scored track record, misses included.

Get the Next Insider Buy the Moment It’s Filed.

This page shows the last 30 days. Pro members get each qualifying buy as an alert; Watchlist members get the ones on stocks they follow. Free for 7 days, cancel any time.

All figures on this page come from public SEC Form 4 filings, processed automatically by our own systems and not independently audited. Insider buying does not guarantee a stock will rise, and past performance is not indicative of future results. InsiderWatch is an informational service based on publicly available information only and is not financial, investment, legal, or tax advice.
