Jason Zweig will discuss his latest book, The Devil's Financial Dictionary, and how he went about distilling everything he had learned in almost three decades as an investing journalist into definitions of Wall Street terms that are, in many cases, only a few words long. Markets are driven much more by psychology and history than by economics. In writing The Devil's Financial Dictionary, Zweig was guided largely by a saying of his father's: "It's remarkable how much you have to learn in order to realize how little you need to know."
