Abstract: A computerized system, computer-implemented method, and/or computer-readable medium for analyzing of a portfolio of tax-lots to facilitate maximization or optimization of after-tax wealth over a specified time horizon, by determining a sequence for selling of individual tax-lots, across an entire portfolio of taxable equity security tax-lotsin a manner that achieves the maximization or optimization of after-tax wealth over a specified time horizon, by performing processing to identify the (i) selling first those tax-lots, in descending sequence, that by doing so would generate the greatest excess after-tax returns, or alpha, and (ii) then, if additional sales are desired, selling in a manner that gives up the least opportunity cost of doing so by selling first, in ascending order, those tax-lots with the least after-tax return potential remaining.

Abstract: A computerized system and method process financial securities and instruments to accurately determine and optimize the after-tax proceeds an investor could expect to have at the end of a holding period for each of a set of investment strategies and determines an optimal strategy for maximizing such after-tax proceeds.
