Or he’s a poor gambler with a rich poker habit. The point is, people sell investments to make money for lots of reasons. He has a track record of selling shares once or twice a year, which he is allowed to do.
It’s his money and he wants cash now. For him a little cash now is better than (maybe) a lot of cash later.
I don’t think one insider selling, with a history of selling shares, is a big deal. If several more start selling, then I would be concerned. Don’t forget, in tough times a lot of CVM execs took shares instead of salary.
This also tells us that he isn’t privy to non public knowledge, so CVM is still blinded.
