ARTICLE
ABSTRACT
The main purpose of this article is to present characteristics of a two-asset portfolio in case of present values of assets being given by a triangular fuzzy number. Fuzzy expected discounting factor for a portfolio and imprecision risk assessments for the imprecision burdening a portfolio were appointed throughout the paper. Thanks to this, the influence of portfolio diversification on an imprecision risk was analyzed and some interesting conclusions were stated.
KEYWORDS
