What's he gonna do anyway fire himself? It doesn't even have to be a mistake. Imagine I have a large investment firm, I make investment decisions in this firm. I own Johnson and Johnson shares both at my firm and personally, I decide J&J is no longer a good investment. I decide to sell both but personal obviously first because when the firm starts offloading, the price will fall at Berkshire trade sizes. I do not have a conflict on interest because they are basically the same interest and investment to me. But as a boss, what I do care about is my employees clouding their judgement because their personal stakes and that of my company are in conflict. Warren doesn't have that conflict because of how much of Berkshire he owns Honestly it may be even worse if he doesn't follow his company, investors in berkshire would wonder, why the hell are they selling but Warren still holding, are his employees worse than him?
