I believe according to law and contractual agreements, those execs are allowed to sell only for a brief period, a short window, and it may be several months or even a year before they can sell again. This latest sell-off was chump change compared to the selling a few years ago, by a whole slew of Echostar execs including Mark Jackson, Dave Kummer, the departed Soraya (can't spell her name) and several others. Those folks collected anywhere from 6 - 12 million dollars, each!. This latest sell-off means nothing.
