Fixed-mix rules in an evolutionary market using a factor model for dividends

Konstantinos Mavroudis, Craig Nolder

In this paper we explore the impact of various constant-proportions investment strategies (or Fixed-Mix Rules) in an economic evolutionary market. Dividends are generated according to a new Dividend Factor Model. Furthermore, Dividends were estimated and calibrated from data using Principal Component Analysis. Moreover, we perform simulations to study the long-run outcome of an evolutionary competition with several well diversified constant-proportions strategies, among them some innovative strategies. We present and compare a variety of simulations with dividends being artificially generated according to our Dividend Model. Our simulation results are important for both theoretical and prac- tical reasons. In theoretical terms we have a model where, although the true rational strategy is the only probable dominant strategy, it is also possible for some "behavioral" rules to perform better under specific circumstances. In practical terms we suggest new constant-proportions strategies that could be superior for investors at least in the short run.
