On Sep 7 their stock was $142.72. One week later it's at $95.64.I'm not sure. To me, when it was reported to the public is when their share price would be impacted. That key personnel involved in the prices sold stock during that window is problematic. Maybe it's not illegal, but it's sure pretty sorry to profit off your (unwilling) customers lack of information.
Thank goodness their execs were able to make a few bucks before their stock took a big hit.
