An insider transaction occurs when a company executive that has non-public information about a company buys or sells shares of their company’s stock. Insiders, such as CEOs, COOs, and CFOs, are required by law to regularly report their stock purchases and sales to the Securities and Exchange Commission.
Tracking a company’s insider transactions is a metric that can be used to identify the direction that its executives believe that its stock is heading. If several insiders sell shares of their company at once, they may believe that the company will have weak future earnings and that the share price will decline in the near future.
For example, if Microsoft's CEO, CFO, and COO all recently sold shares of Microsoft stock, that would be an indication that there could be unreported news that may negatively affect Microsoft's stock price.
