Sorry I didn't see it.
Ben Fuschino has been the founder, CEO , a director, major shareholder for over 10 years. There was never a COO at JSHG so I surmise that some algo interpreted that as he resigned as there was a vacant COO job.
Anyways, nothing has changed in the corporate structure as there never was a JSHG COO.
Probably a short seller tweeted this out.
Just a guess.
