Multivariate methods in description of fundamental power index: Theoretical aspects

Multivariate methods is group of methods encompassing the simultaneous analysis of more than one observation and variable. The application of this group of methods is a very wide and useful in many field of science. One of them is economy, especially sphere of investment and finance. Some of multivariate method are treated as alternative approaches in risk diversification – what is usually named – non classical risk diversification. It is result of universal usage methodological aspects for multivariate methods which enable to: sort, classification or grouping objects (or variables), what is obviously connected with type of method or kind of research.
The main goal of the paper is to indicate usage of multivariate method in description and construction of fundamental power index (FPI). The FPI construction is a result of horizontal and vertical risk diversification development and wider usage methods of fundamental analysis and quantitate methods too. This index can be an alternative measure in analysis of investment attractiveness for stock companies. It becomes important to select and incorporate the most important factors enabling an objective definition of the problem. So that usefulness of multivariate methods seems to be natural. But there are some problems which should be discussed because definition of the factors and attempt to analysis of them is result of their specific importance in risk diversification (especially portfolio analysis) or wider investment on the capital market and specific influence on investment process with usage selected  multivariate methods.
