While transactions from an insider shouldnt be used as the sole item to make an investment or trading decision, an insider buying or selling stock in their company can be a good added factor that leads to more conviction in a decision. Insiders buying stock after a notable sell off can indicate an insiders long-term belief in the success of the company; insiders buying stock at new highs can be an indication the exec doesnt feel the stock is overvalued. Insiders who sell stock at new lows could be anticipating some capitulation moment. If the insider sells at new highs, it could point to the intention to take some profit and lock in a gain. Important Transaction Codes 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 companys 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.See more from Benzinga Stocks That Hit 52-Week Highs On MondayC 2020 Benzinga.com.
