Once a portfolio has been designed and implemented, what happens next? Studies show that asset mixes as well as proper rebalancing are keys to successful ROI. However, a portfolio based on certain historical statistical and financial analysis during a specific period in the past may only be valid for an indeterminate length of time. Macro and micro economics and their accompanying market conditions are continuously changing. So, how does an investment manager decide when it’s time to rebalance a portfolio?
