The rebalancing of an investment portfolio is the action of bringing a portfolio that has deviated away from its target asset allocation back into line. Now underweighted securities can be purchased with sales of the now overweighted securities. Rebalancing can be automated on VestmarkONE at either the account level or across all the advisor’s accounts. Advisors and firms must select the time period at which rebalancing will be done. Some firms conduct rebalancing manually to ensure no unwanted or deminimus trades.
