Abstract

The objective of this research is to investigate how Sino-US trade tensions affect the stock performance of publicly traded firms in the A-share high-tech sector. The direction, magnitude and duration of the impact of the trade war event on the return rate of A-share high-tech stocks were analyzed through the event study method and positive and negative comparative analysis method, and the market value change was further estimated. The research will focus on sub-sectors such as information technology and communications, biotechnology and medical health, and advanced manufacturing, and compare and analyze the differences of different industries affected by the trade war. The theoretical significance of this study lies in expanding the perspective of research on the impact of trade friction on enterprises and enriching the relevant research content; The practical significance is to provide decision-making reference for enterprises to deal with trade war, provide investment advice for investors, and provide basis for the government to formulate relevant policies.
