Relação bilateral sino-brasileira e sua influência no valor de mercado de empresas frigoríficas de capital aberto: um estudo de eventos na B3 nos anos de 2015 a 2023

Abstract

From the 2000s onwards, the strengthening of Brazil and China relationship, driven by south-south cooperation, had a direct impact on the Brazilian meatpacking sector, expressed through the facilitation of agreements, removal of sanitary embargoes and the enabling of more plants for exportation. Based on that, this article identifies the effect of 20 news articles published in the newspaper Valor Econômico (RJ, 2000-current), which report significant events in the meatpacking sector, influenced by International Relations agents, on the stock returns of 4 listed companies at B3 that operate in this sector. Using the Event Study methodology, during the period from 2015 to 2023, the research confirms the main hypothesis: stock returns responded positively to events, especially one day before their announcement.
