Customer momentum has been demonstrated to be effective in the US and Japanese stock markets but has not been examined using a large global supply chain network. In this article, the authors propose a new customer momentum strategy based on global supply chain network data combined with prior research. They apply (1) network theory, (2) medium-term momentum propagation, and (3) higher-layer customer information based on the characteristics of global supply chain network data. Empirical analysis in global stock markets confirms that the proposed strategy has 4.5% annual return based on a long-short analysis. This strategy is more effective than standard momentum and customer momentum in former studies.
