Regularly rebalancing portfolios is one of the key duties of trustees and other fiduciaries responsible for managing institutional portfolios. Asset allocations are set to provide a predetermined risk/reward profile that fits a fund’s objectives and constraints. Portfolios are rebalanced when they drift away from policy target in order to maintain the risk/reward profile implicit in the original asset allocation. How often should clients rebalance their portfolios? What guidelines should clients use to determine when to rebalance? What are the costs and benefits associated with rebalancing? This paper takes a rigorous look at rebalancing, and provides some guidelines for implementing a rebalancing policy.
