Abstract
O mercado é eficiente se novas informações relevantes causarem variação no retorno das ações. As ações podem ser afetadas por eventos e isso pode causar oscilações. A pesquisa analisa a reação do mercado à divulgação de informações sobre a maior instituição de educação listada na B3. Foi utilizado o estudo de eventos para confrontar o comportamento do retorno das ações no período de 30 de setembro 2015 a 30 de setembro de 2017. A pesquisa parte da teoria de mercado eficiente. As informações selecionadas foram distribuídas em grupos, sendo: A - Divulgação dos resultados trimestrais; B - Operações de compra e venda de participações; C - Mudanças relacionadas ao Financiamento Estudantil. Os resultados evidenciaram que a reação que caracterizou o fator mercado eficiente foi identificada no Grupo C, em parte corroborada pelo comportamento do preço da ação.
