摘要

本研究考察了国内和美国宏观经济新闻以及与大流行相关的事件对拉丁美洲和北美国家金融市场的日内影响。我们发现，美国宏观经济指标，特别是那些与货币政策和实际活动相关的指标，对指数回报和波动性的影响比国内新闻更大。大流行进一步改变了市场反应，疫苗开发消息普遍增加了各区域之间的波动性，而疫苗管理在拉丁美洲和北美市场的影响则截然不同。该研究强调了具体情况和信号转换效应的重要性，强调了金融市场的全球互联性，特别是在危机时期。

Intraday impact of macroeconomic and COVID-19 news on Latin American stock indexes

This study examines the intraday impact of domestic and US macroeconomic news and pandemic-related events on financial markets in Latin and North American countries. We find that U.S. macroeconomic indicators, particularly those related to monetary policy and real activity, have a stronger effect on index returns and volatility than domestic news. The pandemic further altered market responses, with vaccine development news generally increasing volatility across regions, while vaccine administration has contrasting effects in Latin American and North American markets. The study emphasizes the importance of context-specific and sign-switch effects, highlighting the global interconnectedness of financial markets, especially during times of crisis.
