Under the assumption of normally distributed returns, we analyzewhether the Cumulative Prospect Theory of Tversky and Kahneman (1992)is consistent with the Capital Asset Pricing Model. We find that in everyfinancial market equilibrium the Security Market Line Theorem holds.However, under the...

This paper shows that a stock market is evolutionary stable if andonly if stocks are evaluated by expected relative dividends. Any othermarket can be invaded by portfolio rules that will gain market wealthand hence change the valuation. In the model the valuation of assetsis given by the wealth...

This note shows that an investor who does not hold positive amounts of all available assets is eventually overtaken by a completely diversified rival investor.

This paper presents an application of evolutionary portfolio theory to stocks listed in the Swiss Market Index (SMI). We study numerically the long-run outcome of the competition of rebalancing rules for market shares in a stock market with actual dividends taken from firms listed in the SMI....

In this paper we analyze the long-run dynamics of the market selection process among simple trading strategies in an incomplete asset market with endogenous prices. We identify a unique surviving financial trading strategy. Investors following this strategy asymptotically gather total market...

The paper analyzes the process of market selection of investment strategies in an incomplete market of short-lived assets. In the model under study, asset payos depend on exogenous random factors. Market participants use dynamic investment strategies taking account of available information about...

This paper studies the evolution of wealth shares of portfolio rules in incomplete markets with short-lived assets. Prices are determined endogenously. The performance of a portfolio rule in the process of repeated reinvestment of wealth is determined by the wealth share eventually conquered in...

We develop a method that allows one to compute incomplete-market equilibria routinely forMarkovian equilibria (when they exist). The main difficulty to be overcome arises from the setof state variables. There are, of course, exogenous state variables driving the economy but, in anincomplete...

The paper examines a game-theoretic evolutionary model of a …-nancial market with endogenous equilibrium asset prices. Assetspay dividends that are partially consumed and partially rein-vested. The traders use general, adaptive strategies (portfoliorules), distributing their wealth between...

The paper examines a game-theoretic model of a …nancial market inwhich asset prices are determined endogenously in terms of short-runequilibrium. Investors use general, adaptive strategies depending onthe exogenous states of the world and the observed history of thegame. The main goal is to...
