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 selling at new highs can indicate that exec wants to take some profit and lock in a gain.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 companys stock moving forward.
