摘要翻译：
新冠肺炎疫情在许多领域产生了颠覆性变化。这里我们重点关注疫情期间人们感受到的焦虑与对金融市场未来表现的信任之间的关系。准确地说，我们的想法是，谷歌对“冠状病毒”的搜索量可以被视为焦虑的代表，并与股票指数价格一起，可以用来在国家一级产生悲观和乐观的情绪指标。我们根据人类发展指数加上中国和它们各自的主要股票市场指数来分析“非常高的人类发达国家”。也就是说，我们提出了悲观和乐观的时间和全球衡量标准，并相应地提供了指数和国家的分类。结果表明，在悲观和乐观方面存在着不同的国家和市场集群。此外，随着2020年6月中旬越来越多的乐观情绪蔓延，特定的制度也随之出现。此外，政府对疫情反应不同的国家经历了不同水平的情绪指标，因此封锁不太严格的国家乐观程度更高。

英文摘要：
  The COVID-19 pandemic has generated disruptive changes in many fields. Here we focus on the relationship between the anxiety felt by people during the pandemic and the trust in the future performance of financial markets. Precisely, we move from the idea that the volume of Google searches about "coronavirus" can be considered as a proxy of the anxiety and, jointly with the stock index prices, can be used to produce mood indicators -- in terms of pessimism and optimism -- at country level. We analyse the "very high human developed countries" according to the Human Development Index plus China and their respective main stock market indexes. Namely, we propose both a temporal and a global measure of pessimism and optimism and provide accordingly a classification of indexes and countries. The results show the existence of different clusters of countries and markets in terms of pessimism and optimism. Moreover, specific regimes along the time emerge, with an increasing optimism spreading during the mid of June 2020. Furthermore, countries with different government responses to the pandemic have experienced different levels of mood indicators, so that countries with less strict lockdown had a higher level of optimism.
