Co-relations Between US Firms with Their Chinese “Supplier” Firms and the Co-movement of Their Stock Returns

Abstract

The paper investigated whether synchronised movements of stock returns happen between US “customer” firms with their Chinese “supplier” firms. Using stock return data of related US and Chinese firms between 2000 to 2019, through OLS regression and Fama-MacBeth regression, I found that there is a prove of the existence of co-movements. The paper also found that during early period of that 20 years (2000 – 2009), the co-movements are stronger than later period
