1. A method, related to the performance of a plurality of investments and implemented by a computer coupled to a database of investment data, the computer being programmed to perform the steps of the method, comprising: determining by the computer, by referring to the database, initial values of a plurality of performance measurements for each of the plurality of investments; calculating, by the computer, a first standardized value for each of the initial values of the plurality of performance measurements for each of the plurality of investments, wherein each first standardized value is a number of standard deviations that a value of a performance measurement deviates from a mean of all corresponding values of the performance measurement for all of the plurality of investments; with respect to any particular performance measurement for which a lower initial value reflects a better performance, multiplying by the computer, corresponding first standardized values for that particular performance measurement by a factor of negative one; for each of the plurality of investments, calculating by the computer a weighted average of corresponding first standardized values for each of the plurality of performance measurements as resulting weighted averages; calculating a second standardized value for each of the resulting weighted averages, wherein each second standardized value is a number of standard deviations that a resulting weighted average deviates from a mean of all resulting weighted averages for all of the plurality of investments; and performing, by the computer, a mathematical conversion on the second standardized values, as an investment analysis, wherein a highest second standardized value is mapped to one hundred percent, a lowest second standardized value is mapped to zero percent, and any other second standardized values are mapped proportionally within a range from zero to one hundred percent accordingly.
