Abstract: A method for performing attribution analysis with respect to an investment portfolio is provided. The method includes: identifying a set of attributes, such as asset class, time period, risk profile, liquidity profile, and/or geographic region, of the investment portfolio; generating a graph that indicates respective relationships among attribute-related decision points that impact the investment portfolio; and calculating, based on the respective relationships among decision points, a respective attribution result for each individual attribute, in order to obtain a set of attribution results that is associated with the investment portfolio. The calculations of the attribution results are independently performable and may be performed in parallel.
