I think we're about to see a run to infinity and beyond, but this does seem a little toppy if the CEO is really preparing to sell shares and employees are finally going to be able to afford new homes, Tesla autos, boats and other new toys... The old saying about a bird in the hand is too true. When the tech bubble burst a lot of new issue holders said to themselves would have, should have, could have. Personally I would have should have could have pocketed a million from an ipo I once participated in and kept a bunch of shares for the future... Unfortunately the future came and took much of it away
If your CEO tells you that better days are ahead and then files to sell a bunch of shares then that's saying something.
FYI, Uncle Sam is going to take a big chunk from each employee that sells shares... If you are one of the lucky employees who can sell a bunch then be sure to save half for tax season and don't spend a dime of that half until your account gets to take a look at your returns.
