Abstract: A methodology for weighting individual securities maintained within a known index investment fund, and reconstructing the proportionate holdings of each of the stocks within the index investment fund as function of the calculated weighting. Typically, index funds securities are weighted by analysis and calculation of the market capitalization of the underlying company. The inventive method and system instead considers each of the constituent securities in a known index fund and weights each said constituent security based upon a revenue weighting analysis. The known index fund is then reconstructed using the same constituent securities, and using the revenue weighting analysis to reproportion the holdings of each of the constituent securities as a function of the total revenue for the securities within the index fund.
