Gary Griffiths was a vice president for a railroad. The CEO asked him to prepare an inventory of all the rolling stock the company owned and to arrange trips among its rail yards for a group of men in suits. Employees began asking Griffiths if the company would be sold and whether they would lose their jobs. Indeed, the company was exploring sale options. Griffiths went to visit his brother-in-law, Rex, who the next day purchased $400,000 in stock of the company. For a month, Griffiths called regularly, and each time Rex bought more stock. In total, he spent $1.14 million on company stock. After the company was sold, Rex made a substantial profit. .Did Gary and Rex engage in illegal insider trading? Was the fact that men in suits were touring the rail yards material nonpublic information?
