Financial performance indicators are the most sought-after diagnostic methods by enterprise's stakeholders, such as profitability, payable capacity and capital management, however, a growing interest has been redirected to the social reflexes of business activities, beyond the economic result. One of the contemporary ways of evaluating social indicators is by analyzing quotients from the Value Added Statement (VAS). After selecting economic and social performance variables, the present paper aimed to investigate the possible correlation between such constructs in the non-cyclical market segment of the Brazilian stock market. Data collected by analyzing the individual financial statements of the entities selected revealed a strong canonical correlation between social performance and economic performance, with highlights to the correlated power between return on equity (ROE), indebtedness and the potential of the entity's net equity to generate added value.

Asset pricing models represent one of the most discussed and researched areas in finance. They are widely used in a theoretical and practical manner to model and predict risk and return to price securities and portfolios as well as in corporate finance to estimate the cost of capital and rank investment projects. They provide a usable measure of risk that helps managers and investors determine what return they deserve for putting their money at risk. The objective of this paper is to analyze the performance of the learning-augmented conditional CAPM model of Adrian and Franzoni (2009) when applied to the returns of the most liquid stocks transactioned in the Brazilian stock market from 1987 to 2010. Adrian and Franzoni (2009), in their paper, complemented the conditional CAPM literature by modeling a new type of time-variation in conditional betas. In this environment, investors form expectations about the long run level of factor loadings from the observation of realized returns of exogenous variables. As a direct consequence of this assumption, conditional betas are modeled using the Kalman filter. Using data of 25 portfolios sorted by size and book-to-market ratio, the authors concluded that the learning-augmented conditional CAPM is able to substantially reduce the pricing errors when compared to the original version of CAPM. Thus, we contribute to the pricing asset literature, as we evaluate whether this model is able to reduce pricing errors in relation to its original version when applied to Brazilian individual asset data. The results of this article showed a decreasing in the pricing errors of learning-augmented conditional CAPM in relation to CAPM in its original version. Our empirical results suggests that the learning about betas should be taken into account when estimating both conditional and unconditional CAPM. [ABSTRACT FROM AUTHOR]

O Modelo de Valor Presente (MVP) -- conceito de que os preços correntes dos títulos dependem do valor presente de dividendos futuros descontados, em que a taxa de desconto é equivalente à taxa requerida de retorno--é um dos conceitos da Teoria Financeira. O objetivo deste artigo é analisar a validade do MVP entre preços e dividendos ao nível da firma a partir de técnicas em painel aplicadas a processos não estacionários e potencialmente cointegrados para o mercado acionário brasileiro. Considerando-se o Modelo de Valor Presente com Retornos Constantes e Variantes no Tempo, a evidência de que (log de) preços reais e (log de) dividendos reais são não estacionários I(1) e que (log da) razão preço-dividendo é I(0) não pode ser rejeitada. Em relação aos estimadores FMOLS e DOLS para modelos cointegrados em painel, verificam-se que os preços das ações encontram-se sobreavaliados sob ambas as hipóteses de retornos constantes ou variantes no tempo.

Fama and French (1993) verified that the asset returns of the U.S. economy can be explained by factors linked to characteristics of companies. The Brazilian literature on the subject corroborates this claim. Our work examines whether the Fama-French model, applied to investment portfolios with variable weightings, still explains the returns, in view of the structural break in the Brazilian stock market in terms of its liquidity. We used the most liquid stocks, both individually and in portfolios. We found that the factors 'size' and 'book-to-market' no longer explain the returns on the Brazilian stock market.

Neste artigo, a teoria de cópulas é utilizada para analisar os co-movimentos entre os mercados de capitais do Brasil e dos EUA. Na finalidade de implementação de uma estratégia de alocação de ativos é importante entender os eventos extremos - tanto os positivos (boom) como os negativos (crashes) - e seus efeitos sobre os mercados. Os índices de mercado usados são o IBOVESPA e o S&P 500 cobrindo o período de 03/2001 a 04/2007. A aderência aos log-retornos das principais cópulas encontradas na literatura financeira é avaliada. Os seguintes critérios foram escolhidos: o Log-likelihod, o critério de informação de Akaike e o critério de informação bayesiano. Os resultados mostram que a cópula de Joe-Clayton simetrizada é a mais adequada para modelar a estrutura de dependência entre os log-retornos do IBOVESPA e os do S&P500. Este trabalho difere de alguns estudos já realizados [e.g. Mendes e Moretti(2005) e Canela e Collazo(2005)], pois leva em consideração a modelagem de cópulas dinâmicas introduzida por Patton (2006). Finalmente, através dos índices de dependência caudal ao longo do tempo, pode-se concluir que a ocorrência de eventos extremos negativos (crashes) no mercado norte-americano tende a afetar mais o mercado brasileiro quando da comparação da ocorrência dos eventos extremos positivos (booms).

This paper investigates the relation between the ratios resulting from the two different possibilities of ROE decomposition (known in literature as DuPont and modified DuPont analysis) and Brazilian firms' stock returns. Differently from traditional DuPont analysis, the modified DuPont analysis explicitly splits operating and financial performance. To put in practice our analysis, we consider Brazilian firms listed from 1995 to 2008. Our results suggest that ROA (derived from traditional DuPont analysis) has higher explanatory power than operational ROA (derived from modified DuPont analysis) regarding stock returns. Further results show that operating components better explain stock returns than financial components. [ABSTRACT FROM AUTHOR]

Stock market indices' rate of return distributions is a recurrent theme in financial literature, especially because some models require the normality assumption as premise. Following the works of Ingersoll Jr. (1987) and Hamada & Valdez (2004), the empirical distribution of the Ibovespa and S&P500 rates of returns from 1986 to 2006 was analyzed. As reported by some others authors, for both indices, the results evidenced that the normality assumption can be highly questionable, because other theoretical distributions from the elliptical family fitted the data better. The rates of return for the Brazilian and American indices showed leptokurtosis, and, in the Brazilian case, asymmetric shape, so that only distributions that deal with these parameters in a less restrictive way, as the Logistic or Log-logistic distributions, can show a better fit to the observed data.

This paper examines the performance of a general dynamic equity indexing strategy based on cointegration, from a market efficiency perspective, observing the different levels of risk and regimes. This new portfolio will be compared with Markowitz portfolio model. The identification of these autoregressive regimes in the process of generating returns in the Brazilian Market, especially in Bovespa, for the Plano Real period (January of 1995 to September of 2004), will be elaborated trough a Markov Switching Model. With this model, is possible to identify the nonlinear structure of the data and it is relation to the conditional mean and conditional variance. As result the dynamics of the data generation process, the returns can be described as function of the growth cycle ("bull markets") and decrease ("bear markets"). [ABSTRACT FROM AUTHOR]
