> What else would he say since he still owns a ton of stock even after the sale? On the other hand, why else would someone sell 30% of their stock? It's not unusual for someone to announce a plan for complete divestment (usually over the course of several years, to avoid disrupting the market) - that's what Gates is doing with Microsoft, in fact. If he's holding on to 70% of his stock, it's not like he thinks Twitter is doomed. And as such a large shareholder and board member, it's not like he's just pretending in bad faith to sell only 30% now, but secretly planning on announcing that he's selling the remainder in another year or two. That would be very illegal, and the SEC would come down on him hard.
