Patent ID: 8659605

Claim:
An apparatus comprising: a non-transitory computer-readable storage medium that stores a computer-readable form of a non-unary tree that relates a plurality of stock market indices to a first stock market index, the plurality of stock market indices comprising a second stock market index and a third stock market index, wherein a first plurality of the plurality of stock market indices are descendents of the first stock market index in the non-unary tree, wherein a second plurality of the plurality of stock market indices are descendents of the second stock market index in the non-unary tree, wherein a third plurality of the plurality of stock market indices are descendents of the third stock market index in the non-unary tree, wherein the first stock market index is a parent of the second stock market index in the non-unary tree, and wherein the second stock market index is a parent of the third stock market index in the non-unary tree; at least one computer programmed to determine a visible representation based on the computer-readable form of the non-unary tree stored in the non-transitory computer-readable storage medium, the visible representation comprising a first region approximately shaped as a circle to represent the first stock market index, a second region approximately shaped as an annular sector to represent the second stock market index, and a third region approximately shaped as an annular sector to represent the third stock market index, the second region being radially-adjacent the first region, the third region being radially-adjacent the second region, the third region having an arc angle that is approximately equal to an arc angle of the second region times a sum of market capitalization weights of the third stock market index and the third plurality of the plurality of stock market indices that are descendents of the third stock market index in the non-unary tree divided by a sum of market capitalization weights of the second plurality of the plurality of stock market indices that are descendents of the second stock market index in the non-unary tree; and a display device that displays the visible representation determined by the at least one computer, wherein the first region is displayed with a first interior color that is based on a change in price of the first stock market index, wherein the second region is displayed with a second interior color that is based on a change in price of the second stock market index, and wherein the third region is displayed with a third interior color that is based on a change in price of the third stock market index.
