Method and computer program for tax sensitive investment portfolio management

Abstract

Methods and corresponding systems are provided for managing investment portfolios that includes the steps of identifying at least one security of the investment portfolio to be sold during rebalancing of the investment portfolio, and rebalancing or deferring rebalancing of the investment portfolio based at least in part on a rebalancing threshold for short-term capital gains or losses, investor specified or otherwise. If an implied total short-term capital gain or loss, e.g., a loss or gain that would occur if the at least one security were sold, falls within the rebalancing threshold rebalancing occurs, otherwise rebalancing is deferred for a later time.

         31 . A system for managing investment portfolios comprising at least one computing device having software associated therewith that when executed performs a method comprising:
 identifying at least one investment portfolio security to be sold in connection with a rebalancing of the investment portfolio;   randomly allocating the at least one investment portfolio security to at least one of a plurality of tax lots associated with the at least one investment portfolio security to be sold;   computing an implied total short-term capital gain or loss that would result from the sale of the at least one investment security from the at least one tax lot; and   rebalancing the investment portfolio if the short-term capital gain or loss, which would result from the rebalancing of the investment portfolio, falls within a threshold for short-term capital gains or losses, and not rebalancing the investment portfolio if the short-term capital gain or loss does not fall within the threshold.   
     
     
         32 . The system of  claim 31 , wherein the method comprises identifying a plurality of securities to be sold in connection with the rebalancing of the investment portfolio based on a difference between securities in the investment portfolio and a target portfolio. 
     
     
         33 . The system of  claim 32 , wherein the plurality of securities to be sold are identified by allocating the securities to be sold to at least one tax lot associated with the securities to be sold and computing an implied total short-term capital gain or loss that would result from the sale of the plurality of securities to be sold from the at least one tax lot.
