Two-assets portfolio with trapezoidal fuzzy present values

Krzysztof Piasecki , Joanna Siwek


The main purpose of the following paper is to present characteristics of a two-asset portfolio in case of present values of composing financial instruments being modelled by a trapezoidal fuzzy number. The future value is described as random variable under the Gaussian distribution of probability. The expected discount factor is defined with the use of simple return rate. Obtained model is an extension of the Markowitz theory to fuzzy case. Throughout the analysis a fuzzy expected discount factor and imprecision risk assessments are calculated. Thanks to that, there arises a possibility to describe the influence of portfolio diversification on imprecision risk. Presented theoretical inference and obtained conclusions are supported by numerical example.
