For the 1978-87 period, in a sample of 344 firms, a negative risk/return association was detected in eight sectors and a positive or neutral one in only two sectors. Pooling together data for the 344 firms, a negative relationship between risk and return was found. After splitting the sample according to firm profitability, an essentially negative risk/return association was identified in the less profitable half of the firms studied, both within and across sectors. On the other hand, the more profitable firms in the sample exhibited a lack of significant association between accounting risk and return, within and across sectors. / Na pesquisa, que é a parte nuclear desta tese, investiga-se a relação entre risco e retorno contábeis em 10 setores econômicos brasileiros. No período 1978-87, com amostra de 344 empresas, detectou-se associação risco/retorno negativa em oito setores e positiva ou neutra em apenas dois. No todo da amostra, sem divisões setoriais, também se encontrou relação negativa entre risco e retorno. Dividindo as firmas entre mais e menos rentáveis, achou-se uma associação risco/retorno essencialmente negativa na metade das empresas menos lucrativas e ausência de associação entre as duas variáveis na metade das firmas mais lucrativas, tanto dentro dos setores como para toda a amostra.
