Could he have timed the announcement around his sales, or would that be something that legal would have to have ensured wasn’t happening?
If this was ongoing and regular for years then yeah it’s nothing. If there are protections in place to ensure announcements aren’t timed around the schedule then that’s even more nothing (as long as it can be proven that procedure was followed).
It still seems like a system that can easily be manipulated, but yeah if it’s legal then it’s legal and there really can’t be any punishment regardless of ethics or optics…
