On the investor’s tendency to risk/earn on the stock market

In this paper we analyze the investors’ tendency to risk/earn on the stock market. In particular, we distinguish between two different phases of this analysis: we first value the ex-post wealth obtained by several optimal portfolio strategies in order to propose a questionnaire that covers all preferences held by some potential investors. Then we analyze the behavior of each investor on a homogeneous scale with respect to the latent variable (tendency to risk/earn) in order to characterize the optimal choice for each admissible investor. Finally, we comment the results of statistics obtained from this empirical analysis of the latent variable.
