bibliometria, documentação, finanças, mercado de acções, pandemiaResumo
Este artigo tem como objetivo explorar o risco financeiro durante a era da pandemia nos mercados de ações. Para o efeito, são recolhidos, limpos e analisados 252 documentos da base de dados Scopus entre 2019 e 2022, sob uma metodologia teórico-exploratória com a qual é elaborada uma análise de rede, a partir da teoria dos grafos com Rstudio (Bibliometrix), VOSviewer e Tree of Science. Os resultados indicam uma taxa de crescimento anual do conhecimento de 33,4%, onde a China e os Estados Unidos geraram a maior parte da investigação. Foram identificadas três áreas de trabalho nos grupos desenvolvidos: uma descritiva com um baixo nível estatístico e matemático, a segunda com um nível médio de análise relacionada com estudos de risco sistemático, estabilidade financeira e gestão do risco, e a última com um elevado desenvolvimento analítico da investigação que tentou explicar o defeito da COVID-19 nos mercados financeiros. Finalmente, conclui-se que os países necessitam de estabelecer processos contínuos de informação sobre estes tipos de impactos, uma vez que estudos anteriores demonstraram que as regiões emergentes são muito susceptíveis às permutações sofridas pelas regiões com elevado desenvolvimento económico.
