Portfolio Rebalancing Revisited: What Strategy Optimally Triggers an Adjustment to the Asset Weights? - A New Story in Hong Kong Market

Abstract

This paper examines the robustness of the evidence on rebalancing effects within Hong Kong context and addresses the issue of whether there is an optimal rebalancing strategy that can be historically exploited by wealth managers to earn constant profits in excess of a buy-and-hold strategy in the market index. It finds that although superior to buy-and-hold, no single rebalancing strategy dominates one another under all conditions. The general rule is that patient rather than quick-trigger rebalancing benefits portfolio management. In particular, the superiority of rebalancing mainly comes from market conditions.
