What a fun book this is! The Hour Between Dog and Wolf by John Coates mixes pop finance with pop science, sketching some surprising links between them. I will trust Coates to get the science right (he provides citations). His investigation of financial markets is largely anecdotal and so speculative, but all the same it yields tantalizing suggestions.
Coates is a former derivatives trader -- which gives him authority to describe the subjective experiences of winning and losing at a trading desk. He (somehow) becomes hooked on neuroscience research; he describes himself sneaking away from his Wall Street desk to mix with scientists at Rockefeller University. The book seeks to bring these two worlds together. Coates immerses himself in the activation of hormones: testosterone, cortisol and the like. It is these chemical agents that produce the profound effects on the humors of financial traders, and hence overall market behavior.
Coates attacks the mind/body dichotomy: a financial market trader reacts more like an athlete than an analyst in responding to the stimula communication through his screen. Coates employs emerging understandings of mind/body feedbacks to track the play of traders. The traders can react before they 'see', rely on 'gut feelings' and engage in mano-a-mano combats from which they emerge winners or losers. These are quintessentially physical experiences. The markets themselves may then be understood as projections of this human biology.
