Similarity values are determined between pairs of stocks in a stock market. First, second and third optimum paths are determined which optimize respective functions of similarity values between first, second and third stocks, respectively, and a fourth stock. First, second and third concave regions are displayed to represent the first, second and third stocks, respectively. The third concave region is angularly adjacent the second concave region, but has a radial width that differs from a radial width of the second concave region. The first concave region is radially interposed between the second concave region and a region which represents the fourth stock to indicate that the first stock is in the second optimum path. The first concave region is radially interposed between the third concave region and the region to indicate that the first stock is in the third optimum path.
