A Fraqueza de Segunda-feira observa que as ações frequentemente abrem mais baixas após o fim de semana, enquanto os traders digerem notícias e reposicionam carteiras.
A pressão baixista de curto prazo pode surgir no início da semana antes que os mercados se estabilizem.
Os testes indicam um retorno anual médio de aproximadamente 106%. Funciona melhor no mercado de ações.
A estratégia vende a descoberto na abertura de segunda-feira e cobre ao fechamento, buscando lucrar com essa fraqueza inicial.
Os stops são mantidos estreitos para evitar perdas caso o mercado contrarie a tendência e suba.
