Martha Mart owned stock in Napkin Inc., a company that she is also a director of. During a board meeting, she was informed that a new product that was to be launched by Napkin was not approved by the FDA. Knowing that once this information became public knowledge the stock would tank, she instructed her stockbroker to sell all her Napkin shares. At the time of her sale, Napkin was trading at $60. After the information about the denial of approval for the new product was reported by CNN, the share price fell to $1.50. Was Martha’s action legal? Was it ethical? Why or why not? Who did her actions affect and how?
