- W4386880021 abstract "This paper develops a Russia-Ukraine War Economic Sanctions News Sentiment Index (RUWESsent) to reflect the public sentiment and reaction to economic sanction news based on Twitter Sentiments, Google Trend, Wikipedia Trend, and News Sentiments. Using quantile-on-quantile regression, we document that positive RUWESsent has positively affected FinTech and blockchain market stock returns in a bullish market and a negative impact on a bearish market. The result of the rolling window wavelet correlation again finds a higher negative correlation immediately after the invasion, with further results revealing that negative sentiments negatively impact FinTech and blockchain market stocks. Furthermore, the time-frequency quantile VAR approach shows that RUWESsent is the major transmitter of shock in the network. Our findings imply that negative sentiment induces irrational investor behavior and increases noise trader loss aversion and herding behavior. Our findings have significant implications for investors and policy makers during geopolitical crises." @default.
