A method for creating an index that replicates performance of a specified fund that includes a plurality of holdings issued by companies. The method includes defining plural subsets of the holdings in the specified fund, and, for each subset, determining correlation in performance between that subset and the fund. The method also includes selecting, as a replication index for the fund, one subset from among the plural subsets, based on the correlations in performance between the respective subsets and the fund. The method further includes creating an ETF based on the replication index, and making the ETF available for trading.
