报告摘要:

In this talk, the aims is to investigate the relationship between geopolitical risks (GPRs) and investor sentiment in the U.S. stock market based on the Granger causality test and time-varying parameter vector autoregression (TVP-VAR) analysis. Findings indicate that geopolitical risk indexes, including the general geopolitical risk (GPR), geopolitical threats (GPT), and geopolitical acts (GPA), have evident impacts on investor sentiment in stock markets, whereas investor sentiment does not affect geopolitical risks. More importantly, GPRs have significant negative effects on investor sentiment, suggesting that higher (lower) geopolitical risks dampen (promote) investor sentiment directly or indirectly. Specifically, the reaction of investor sentiment seems more pronounced in the short and medium term than in the long term, and more sensitive to domestic geopolitical events. There is no significant difference in the impacts of GPR, GPT, and GPA. The results obtained are robust for alternative investor sentiment and geopolitical risk indicators.
