Can a CEO short his own company?
(yes, this should probably be a comment, not an answer ... but it's a bit long). I don't know what the laws are specifically about this, but my grandfather used to be on the board of a company that he helped to found ... and back in the 1980s, there was a period when the stock price suddenly quadrupled One of the officers in the company, knowing that the stock was over-valued, sold around a third of his shares ... and he got investigated for insider trading.  I don't recall if he was ever charged with anything, but there were some false rumors spreading about the company at the time (one was that they had something that you could sprinkle on meat to reduce the cholesterol).  I don't know where the rumors came from, but I've always assumed it was some sort of pump-and-dump stock manipulation, as this was decades before they were on the S&P 500 small cap. After that, the company had a policy where officers had to announce they were selling stock, and that it wouldn't execute for some time (1? 2 weeks? something like that).  I don't know if that was the SEC's doing, or something that the company came up with on their own.
