I thought this was going to be interesting but it turns out it was just an advertisement for IEX. They brought out a) guy selling a book about IEX (Michael Lewis) b) CEO of IEX (Brad Katsuyama) c) Chief Strategy Officer of IEX (Ronan Ryan) and d) IEX investor (David Einhorn). No shit they are going to make it sound like the markets are rigged and IEX is the answer.
