Bem como, a utilização de uma ferramenta simples para avaliar os ativos e auxiliar na composição de um portfólio de forma a minimizar os riscos.  Para tanto, foram utilizadas as teorias Benjamin Grahan para a escolha dos ativos a serem adquiridos, e o modelo da fronteira eficiente de Harry Markowitz para definir a participação de cada ativo na composição das carteiras. Para a realização dos cálculos foi utilizada a planilha eletrônica Excel®, uma ferramenta simples e disponível a todos os investidores. O período estudado foram os anos de 2006 a 2010, ou seja, dois anos anteriores e dois anos posteriores a crise mundial de 2008. No inicio do período foram formadas cinco carteiras conforme os filtros de Grahan e a participação de cada ativo foi estabelecida conforme os critérios demonstrados por Markowitz.  Os ativos que compõem a carteira bem como a sua participação no total investido são avaliados e alterados uma única vez no inicio de cada ano.Universidade do Estado de Santa Catarina — UDESC2016-05-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.revistas.udesc.br/index.php/reavi/article/view/2316419004062015028Revista Brasileira de Contabilidade e Gestão; v. 4 n. 8 (2015); 028-041Revista Brasileira de Contabilidade e Gestão; Vol. 4 No. 8 (2015); 028-041Revista Brasileira de Contabilidade e Gestão; Vol. 4 Núm. 8 (2015); 028-0412764-747110.5965/231641900406reponame:Revista Brasileira de Contabilidade e Gestãoinstname:Universidade do Estado de Santa Catarina (UDESC)instacron:UDESCporhttps://www.revistas.udesc.br/index.php/reavi/article/view/2316419004062015028/5420Copyright (c) 2016 Roque Alberto Zin, Edielson Tarsohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessZin, Roque AlbertoTarso, Edielson2022-12-02T15:57:55Zoai:ojs.revistas.udesc.br:article/6652Revistahttps://www.revistas.udesc.br/index.php/reavi/indexPUBhttps://www.revistas.udesc.br/index.php/reavi/oairbceg.ceavi@udesc.br || paulo.barth@udesc.br2764-74712764-7471opendoar:2022-12-02T15:57:55Revista Brasileira de Contabilidade e Gestão - Universidade do Estado de Santa Catarina (UDESC)false
