Abstract

We show, for a wide variety of payoff functions, that the expected log optimal portfolio is also game theoretically optimal in a single play or in multiple plays of the stock market. Thus there is no essential conflict between good short-term and long-run performance. Both are achieved by maximizing the conditional expected log return.
