The BOD has a fiduciary duty to the shareholders to do what is in the best interests of the company. If they were to not PR things that could raise the SP with the idea that they can keep the SP low, accumulate more shares and cash in when things go great later because of what they know that we shareholders do not know, that would be illegal as it is self-serving and they would be held accountable for not upholding their fiduciary duty.
All of those shares would be forfeited, along with other penalties.
