Distributional Analysis of Portfolio Choice

Portfolio Optimization: Distributional Approach

This paper analyses the stable distributional approach for portfolio optimisation. We consider a portfolio optimization problem under the assumption of normal (Gaussian) and stable (nonGaussian) distributed asset returns. We compare the results of portfolio allocations in normal and stable cases.

Latent Class Analysis for Portfolio Choice

We exploit the potential of latent class analysis in order to propose an innovative framework for financial portfolio development. By stressing the latent nature of the most important financial variables, the expected return and the risk, we are able to introduce a methodological dimension in relevant steps of portfolio analysis. First, we provide a test for the number of possible investment ch...

Portfolio Choice Problems ∗

Modern Portfolio Theory, Digital Portfolio Theory and Intertemporal Portfolio Choice

The paper compares three portfolio optimization models. Modern portfolio theory (MPT) is a short-horizon volatility model. The relevant time horizon is the sampling interval. MPT is myopic and implies that investors are not concerned with long-term variance or mean-reversion. Intertemporal portfolio choice is a multiple period model that revises portfolios continuously in response to relevant s...

Portfolio Choice via Quantiles

A new portfolio choice model in continuous time is formulated for both complete and incomplete markets, where the quantile function of the terminal cash flow, instead of the cash flow itself, is taken as the decision variable. This formulation covers a wide body of existing and new models with law-invariant preference measures, including expected utility maximisation, mean-variance, goal reachi...
