Reading an insider's Form 4 history

Corporate insiders — directors, officers, and holders of more than 10% of a company's stock — must report their trades to the SEC on Form 4 within two business days. Looking at one insider's filings over time shows whether they tend to buy on the open market (a discretionary use of their own money, generally the strongest signal), sell, or simply receive and exercise equity awards as compensation.

The track record above measures how this insider's past open-market purchases performed in the months after each filing. Trades made under a pre-scheduled Rule 10b5-1 plan are flagged because they carry no timing signal. To pull any insider's full history programmatically, see the insider trading API or our guide to reading Form 4 filings.
