Resumo:
Este trabalho tem como principal objetivo determinar a relação entre sentimento de mercado e taxas de retorno no principal benckmark português e verificar se essa relação é influenciada pelos diferentes ciclos econômicos. Dada a subjetividade inerente à utilização de variáveis que identifiquem o sentimento dos investidores, o Índice de Confiança do Consumidor (ICC) foi utilizado como indicador de referência. Para alcançar o objetivo proposto, foi realizada análise da estacionariedade das séries temporais, correlação de Pearson e causalidade de Granger utilizando o modelo de vetores autorregressivos e, posteriormente, o Método dos Mínimos Quadrados com variáveis macroeconômicas. Os resultados obtidos sugerem uma relação unidirecional dos retornos do mercado de ações na variável sentimento. De fato, em períodos de recessão, o pessimismo dos investidores induz a comportamentos lineares e a relação sentimento-retorno é mais evidente. Assim, este artigo proporcionará duplo interesse: para a comunidade acadêmica, fornecendo base para investigações futuras, e para gestores e investidores, quanto à percepção de que a previsibilidade dos retornos será mais fácil em períodos recessivos.
