I have zero idea as to why he would resign--the potential reasons are endless. I choose to focus on the fact that on a big percentage down day 354,550 shares were traded--barely more than the average daily volume. This stock is 60% owned by institutions. Of those 354,550 shares, how many do you think were institutional sells? This company will either be a success or not, but IMO the success or failure of this company does not rest on today's news--bought a little more at the close.
