Manually rebalancing a large number of client portfolios can be time consuming and expensive. Today, rebalancing software comes in a wide range of prices and capabilities. Some that rebalance at the individual account level can be very inexpensive, however software that is highly automated, tax sensitive and capable of grouping accounts in a variety of ways can easily cost tens of thousands of dollars. Larger wealth management firms are increasingly investing in sophisticated rebalancing software because the alternate is more expensive and less accurate. As the number of advisors using more sophisticated rebalancing software increases, and as the number of providers of rebalancing software increases, it is likely that we will continue to see a downward trend in the pricing of rebalancing software.
