Abstract

This paper uses a simple stochastic market fraction (MF) asset pric-ing model to investigate market dominance, profitability, and how traders adoptingfundamental analysis or trend following strategies can survive under various marketconditions in the long/short-run. This contrasts with the modern theory of financewhich relies on the paradigm of utility maximizing representative agents and ratio-nal expectations assumptions which some contemporary theorists regard as extreme.This school of thought would predict that trend followers will be driven out of themarkets in the long-run. Our analysis shows that in a MF framework this is notnecessarily the case and that trend followers can survive in the long-run.
