You know how it's recommended to sell employee stock grants asap, so your not over indexed into your employer? I.E. if the company you're working for performs poorly or goes under, you don't want to lose your job and wealth, and if it does well, you'll keep making money at your job anyway, so there's no advantage to investing more of your personal capital into your employer than you would if they weren't employing you (barring insider trading).
