As regressões de painel são aplicadas para analisar as relações entre classificações e sete determinantes. Os resultados mostram cinco determinantes estatisticamente significativos. A segunda parte do estudo examina como as empresas brasileiras listadas reagiram às recentes baixas soberanas emitidas pela Standard & Poor, pela Moody's e pela Fitch. Metodologia do estudo do evento é usada. Todos os eventos apresentam evidências empíricas de retornos anormais negativos, mostrando uma forte correlação negativa entre as ações negativas de rating de crédito eo mercado de ações brasileiro. Ao agregar os eventos, os downgrades ao território da sucata e as mudanças da avaliação de Moody's são aquelas que derrubam estoques retornam o mais.
