Why Insider Transactions Are Important?

Insider transactions shouldn't be used primarily to make an investing decision, however an insider transaction can be an important factor in the investing decision.

Transaction Codes To Focus On

Investors prefer focusing on transactions which take place in the open market, indicated in the Form 4 with codes P for purchase and S for sale. If the transaction was an open-market transaction, that means that the insider made a concious decision for the company's stock moving forward.

Transaction codes other than P or S are often viewed with less conviction as they are often not tied to a decision by the exec. As an example, transaction code C indicates the conversion of an option. Transaction code A indicates the insider may have been forced to sell shares in order to receive compensation the exec was promised upon being hired by a company.
