No, it has to be explicitly outlined in the employee agreement if you’re not allowed to share some of the information. “Duty of confidentiality” is not a magic thing that just exists. All of the cases where people have been busted (e.g. the capital one credit card transactions) are because the SEC has an exact quote from the employee agreement that says something like “don’t use this mega database to do trading”. If your employee agreement doesn’t have something explicitly barring you from noticing racks of incoming inventory and using that information, then it’s not insider trading.
