Introduction. The first part of the paper reveals the concept and features of platinum group metals. According to the complex of considered parameters of each platinum group metals, including the market volume in physical and value terms, we distinguish three major (palladium, platinum, rhodium) and two minor (iridium, ruthenium) metals. For this research, the markets of five platinum group metals are identified as the object for factor analysis. Theoretical analysis.
