How to track insider buying (and what to use)
You can track insider buying by reading the Form 4 filings that executives, directors, and large shareholders must submit to the SEC shortly after they trade their own company's stock. Each Form 4 shows who traded, whether they bought or sold, how many shares, and at what price. You can read them one company at a time on SEC EDGAR, or use a tool that collects them for the tickers you follow. Brief Equity's feed has an Insiders tab that surfaces the disclosed Form 4 history for every stock on your watchlists. One honest limit: this is disclosed filing history pulled into one place, not an instant trade-alert service, and filings are delayed by the reporting window.

What a Form 4 tells you
A Form 4 is the filing an insider submits to the SEC after buying or selling their own company's stock. Insiders here means officers, directors, and holders of more than ten percent of a class of shares. The filing reports the transaction date, whether it was a purchase or sale, the share count, and the price.
Insiders must file within a short window after the trade, so a Form 4 lands quickly but not instantly. The number of shares and the direction are on the form; the reason is not. A cluster of open-market purchases by several executives tends to read differently than a single routine sale.
Buying vs selling: which signal matters
| Transaction | What it can signal | The caveat |
|---|---|---|
| Open-market buy | An insider putting their own cash in at market price | Small buys can be routine or optical |
| Sale | An insider reducing their stake | Often for taxes, diversification, or a pre-set plan |
| Option exercise | Shares acquired through compensation, not conviction | Not the same as an open-market purchase |
The old line is that insiders sell for many reasons but buy for only one. It is a rough heuristic, not a rule. An open-market purchase with an insider's own money is the transaction most people watch; a scheduled sale under a pre-arranged plan carries far less information.
How to track insider buying on your watchlist
- Decide which tickers you care about, since insider filings are only useful in the context of names you follow.
- Pull each company's Form 4 history from EDGAR, or read it through a feed that collects it per ticker.
- Separate open-market purchases from option exercises and pre-planned sales.
- Watch for clusters: several insiders buying in the same window is a stronger tell than one filing alone.
Doing this on EDGAR means checking each company's filings separately, which gets slow across a full watchlist. A feed that already knows your tickers pulls the Form 4 history into one stream, so insider activity shows up next to the other news for those names.
Insider trades in the Brief Equity feed
Brief Equity's feed has an Insiders tab that surfaces the disclosed SEC Form 4 history for the tickers on your watchlists, with filters for transaction and owner type. Because it draws from EDGAR, coverage tracks companies that file with the SEC. It collects disclosed filings into one feed; it is not an instant trade-alert service.
The data is delayed by the filing window and by the feed's own refresh, so treat it as a research signal, not a trigger to act on the second an insider trades. Read a purchase as a lead worth investigating alongside the rest of what you know about the company.

Frequently asked questions
- How do I see when executives buy their own stock?
- Executives disclose those trades on SEC Form 4, filed shortly after the transaction. You can read them on EDGAR one company at a time, or use a feed that collects the Form 4 history for the tickers you follow.
- Is insider buying a good signal?
- An open-market purchase with an insider's own money is the transaction most investors watch, since insiders buy for essentially one reason. Sales are noisier, often driven by taxes or pre-set plans. Clusters of buys carry more weight than a single filing.
- Does Brief Equity send instant insider-trade alerts?
- No. The feed's Insiders tab collects the disclosed Form 4 history for your tickers into one place. The data is delayed by the filing window and the feed's refresh, so it is a research tool, not an instant alert service.
- What is the difference between an insider buy and an option exercise?
- An open-market buy is an insider purchasing shares with their own cash at the market price. An option exercise is acquiring shares through compensation, which says less about conviction. Form 4 distinguishes the two, so read them differently.
