1. A method for analyzing the performance of a plurality of investments requiring use of a computer coupled to a database of investment data, wherein the computer is programmed to perform the method, the method comprising: determining, by referring to the database, a plurality of performance measurements for each investment; calculating a standardized value for each of the performance measurements, wherein each standardized value is a number of standard deviations that a performance measurement deviates from the mean of all corresponding performance measurements; for each investment, calculating a weighted average of the corresponding standardized values for each of the performance measurements; and performing a mathematical conversion on the resulting weighted averages, so that the highest resulting weighted average is mapped to one hundred percent, the lowest is mapped to zero percent and all other weighted averages are mapped proportionally within a range from zero to one hundred percent accordingly.
