So being, we firstly selected shares trading in PSI-Geral, from 1999 to 2011, and then an initial\/historical period were defined, where eight portfolios were established one for each period, and a follow-up period considering one, two and three years holding. By conducting a descriptive analysis to each portfolio individually considering all periods, and a statistical analysis only to follow-up periods, we compare profitabilities and Sharpe¿s index means calculated to ELECTRE III, CAPM, and PSI-20 TR. In the specific case of statistical analysis, we conducted parametric (t-student and ANOVA one-way tests) and nonparametric tests (Kruskal-Wallis and Mann-Whitney tests), subdivided into two analysis: a unit sample analysis from 2005 to 2011; and a two sample analysis, one from 2005 to 2007, and another one from 2008 to 2011.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786202062701\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786202062701","offer_id":39459920117853,"sku":"9786202062701","price":36.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/0e39a66f-74ff-40cd-886f-cd955df80460.jpg?v=1775195915","url":"https:\/\/shop.autorenwelt.de\/products\/financial-theory-applied-to-portfolios-selection-von-antonieta-lima-vasco-salazar","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
