Abstract: This paper aims to study the impact of supply and demand shocks on abnormal fluctuation of stock price. We use event study and regression analysis methods to explain why the supply and demand shocks caused by US–China trade friction in targeting industries can affect the whole Chinese securities market. Our findings reveal a direct effect of shocks that can affect the stock prices of targeted companies. Additionally, there is a network effect in which the supply side and demand side shocks propagate upstream and downstream through the network, in turn affecting the stock prices of nontargeted companies.
