Yes, but it doesn’t rise to the level of “insider trading,” which means using internal-only information to make trading decisions. If they sell these stocks regularly, on a schedule, in the same quantity, it’s not insider trading.
And that’s exactly what they’re doing, you can see their trades, and they’re consistent for about the same amount. So they’re not trading because of changes going on internally, they’re trading based on a schedule, probably because they need cash flow for some reason. My guess is taxes for their stock compensation.
