It’s undeniably a negative signal that the person who essentially knows the company’s finances best considers now a good time to sell. On the other hand, the opportunity to trim one’s holding is twice as good as it was a year ago, which makes it more attractive on a personal level—especially since he is stepping down. Liquidity is also better now. He also acquired these shares at a significantly higher price than the current level, so he’ll get some nice tax deductions to boot.
It will be interesting to see if the selling continues in the coming days.
