Yes, but after the initial grant has vested entirely your opportunities for growth are limited. Here's an example - say I'm hired with 1000 units of stock over four years. Each year I receive a refresher grant of 250 units of stock, again vesting over four years. Once I reach Year 4, my stock compensation stabilizes, assuming my refreshers remain the same (I'm am obviously grossly simplifying - you could be promoted and get larger grants, the company could do badly and your dollar value be significantly reduced). But what you can do, and what the parent is alluding to, is jump ship around year 3-4 and get the company you're going to match your current amount of outstanding stock, meaning your initial grant becomes much higher, and your refreshers do too. At least, that's the idea. It's worked for me. Additionally, although personally I did very well on my refresher grants I know other people at my employer did not. So that's another factor.
