Abstract
In this paper we study the application of a fuzzy algebra to the task of classifying financial investments. A classification system is developed based on several financial indicators and on a fuzzy interpretation of them in terms of linguistic labels and triangular fuzzy numbers. A fuzzy algebra expressly created for clustering and its properties are then discussed. Finally an application example is given using data from a sample of firms whose securities are exchanged in the Boston Stock Exchange.
