RESUMO

Earnings management is an area that has been studied extensively; there are currently several lines of research. A significant part of these studies has examined the results of smoothing (BUCKMASTER, 2001). Income smoothing is defined as the management of results to reduce the variability of accounting results. If the smoothing leads to more information be reflected in stock price, is likely to improve the allocation of resources, being a critical factor in the portfolios creation. Despite demonstrated in the international literature, there is no empirical evidence in Brazil that a smaller range of variance in accounting results favorably affect the assessment of a firm. Given this gap in accounting research, the purpose of this study aims to build metrics to determine the degree of smoothing of results of opened Brazilian companies, decomposing them into two groups: the group of smoothers companies and group of non smoothers companies, and additionally submit evidence on the long-term relationship between the degree of smoothing and the risk and return stock, size, the industrial sector for the period 1998-2007 and finally break what would be the factors explaining the practice of smoothing results of opened Brazilian companies. The database used for searching of search was the Economática and CVM, the sample of the sample was focused on 145 companies. In the segregation of groups, it was found that Brazilian smoothers companies have a smaller degree of market risk than non smoothers companies. In average terms, the beta of companies in the smoothers group is significantly lower than the group of non smoothers companies. Regarding to the return, it was found that the abnormal return adjusted by the market of smoothers companies, when annualized were significantly higher, in respect to size are significant evidence that smaller companies are more prone to have the practice of smoothing. Differences in the average of groups were confirmed when subjected to non-parametric and parametric tests both in methodology in cross section as time series, indicating there is a statistically significant difference in performance in the Brazilian market from those companies that have a smoother profile for non smoother. The results of this research are particularly important for investors averse to risk and who desire higher returns in the structuring of their portfolios. The financial managers are also scientific evidence justifying the execution of a management with positive results (benefical smoothing).
