Application of a Fuzzy Model to Classify the Listed Issuers at the Bucharest Stock Exchange

Abstract

In order to determine some specific economic characteristics that are associated to the size of the companies that are listed and traded on the Bucharest Stock Exchange, it is necessary to classify the companies based on the market capitalization, liquidity and the traded volumes. This paper aims to make a comparative study among the parameters of the classes obtained by a break up into disjunctive classes and a break up using a fuzzy model.
