Estratégias de comercialização da soja: análise de portfólios, sob condições de risco

Abstract

A soja é a cultura mais importante do agronegócio brasileiro. Entretanto, na época da comercialização, os sojicultores defrontam-se com o dilema de "quanto", "quando" e "como" vender sua produção, devido ao fato de a mesma ser uma atividade realizada sob condições de risco e de incerteza. Através da utilização de um modelo matemático de programação quadrática, buscou-se determinar os melhores portfólios, no sentido de maximizar a renda com certo nível de risco, ou minimizar o risco para certos níveis de renda. O portfólio mais eficiente obtido entre todos diz respeito a produtores com "média aversão ao risco" (α = 0,30). Dessa forma, tal plano ótimo de comercialização indica que os produtores de soja do Estado do Paraná poderiam armazenar a produção na época da colheita com posterior venda mensal fracionada, o que representaria um total de 90,8% das vendas concentrando-se nos últimos quatro meses do ano.
