Kelly Criterion revisited: optimal bets
arXiv:physics/0607166 · doi:10.1140/epjb/e2007-00126-3
Abstract
Kelly criterion, that maximizes the expectation value of the logarithm of wealth for bookmaker bets, gives an advantage over different class of strategies. We use projective symmetries for a explanation of this fact. Kelly's approach allows for an interesting financial interpretation of the Boltzmann/Shannon entropy. A "no-go" hypothesis for big investors is suggested.
