My Take
Bill Ackman is, to me, the most theatrical figure in modern finance, and I mean that as both compliment and caution. The Pershing Square founder treats investing as public argument: he takes a position, explains it at exhausting length, and dares the market to disagree. His wins and losses are equally spectacular, which makes him a more honest spectacle than managers who hide behind quiet quarters. I do not always share his conclusions, and his appetite for online crusades can wear thin, but I never doubt that he believes what he says. Conviction that loud is rare, and oddly clarifying.
