Abstract

The stock market in Brazil had a great evolution in the participation of small investors from the currency stabilization and the ease of access to information of public companies using home brokers and the internet . The ease of access and interest by retail investors brought a need for better preparation and understanding of the mechanisms involved in these investments . The preparation of this public suggests the need for a greater amount of technical information in order to assist them in making decisions . These new investors without a proper preparation and a high level of good technical information possibly present weakness in facing financial crises like the 2008 . Moreover , the Bovespa index is comprised largely of commodity companies , there is seen a strong influence of performance concentrated in a few very large companies that are Petrobras , Vale and some banks . For the best view of the market , BM & FBovespa own set of comparative indicators such as: Bovespa Index , the IBrX50 the large Mid Cap , Small Cap , sector indices among others . In general , the indexes are formed having as a criterion only its liquidity and turnover , balance sheet does not include criteria or shareholder return . This methodology led Dow to rethink their criteria for inclusion of companies in such indices . She has revised its classification criteria , including for example, the value of the shares that will be in effect in 2014 , yet no performance criterion in firms' balance sheets was considered . This work , in turn , evaluates asset portfolios formed by companies participating Indexes IBrX50 , large Mid Cap and Small Cap and have higher ROE - Return on Equity . Thus , it can be seen what would be the performance of these portfolios , whereas a given investor had applied its resources to such criteria between September 2008 and September 2013 , ie , exactly five years after the onset of the global financial crisis . The results suggest that the portfolio of companies participating in the Small Cap Index , and higher ROE showed better performance measured by the Treynor Index in relation to a portfolio that had a return in accordance with the Bovespa index . This result has its relevance to the extent that the investor could benefit you had to use a strategy of investing in smaller companies , but the ROE as a selection criterion
