You don't leak it to a reporter like it's the latest variant of the iPhone.
There should have an announcement from the board, a LONG time before markets were to start (ideally end of markets on friday) clearly explaining WHAT is happening and WHY (even if it's a bullshit reason, there should be a reason).
It would have allowed markets to absorb the news instead of the NYSE having to halt trading amid the uncertainty.
people trading off market are taking their own risks willingly, the market itself tries to be fair w.r.t. reported
if you are listed, you effectively agree to release info on certain terms, so that off-market don't get a better advantage also
When I had posted this, there had been no tweet, just a leak from a CNBC reporter with three lines : breaking news, Jack is rumored to be leaving, stay tuned for more info.
there was a massive info asymmetry, so NYSE had to halt trading until it deems news has percolated enough, I guess.
Sending a tweet works just as well to get the message out.
My comment dates from when we didn't have a tweet or any info, no one knew who the next ceo of twitter was, simply the rumour (not even confirmed news) that jack had left. no one knew, Twitter PR was refusing reporter questions and NYSE had to stop trading until the situation settled
