Albota TI - Using Dynamic Programming to Optimally Rebalance Portfolios AID - 10.3905/jot.2006.628191 DP - 2006 Mar 31 TA - The Journal of Trading PG - 16--27 VI - 1 IP - 2 4099 - https://pm-research.com/content/1/2/16.short 4100 - https://pm-research.com/content/1/2/16.full AB - The authors propose a different framework that quantifies the cost of a rebalancing strategy in terms of risk-adjusted returns net of transaction costs. They then derive an optimal rebalancing strategy that actively seeks to minimize that cost. Certainty equivalents and the transaction costs associated with a policy to define a cost-to-go function are used, with the expected cost-to-go minimized using dynamic programming. They apply Monte Carlo simulations to demonstrate that their method outperforms traditional rebalancing strategies like monthly, quarterly, annual, and 5% tolerance rebalancing. They also show the robustness of our method to model error by performing sensitivity analyses.TOPICS: Simulations, portfolio construction, performance measurement
