Um século de tradição: a banda de música do Colégio Salesiano de Santa Rosa (1888-1988)

A música nos colégios salesianos sempre ocupou um lugar de destaque, pois na pedagogiade Dom Bosco é considerada importante fator educativo, devido a seu grande poder deinfluência no espírito dos jovens. Para Dom Bosco, uma escola sem música é um corposem alma , afirmação que explicita o valor pedagógico da música. Ainda segundo ele, aalegria é o elemento básico da educação, e a música expressa esse estado da alma. Estetrabalho visa valorizar a Banda de Música do Colégio Salesiano Santa Rosa, de Niterói,RJ, em sua trajetória de mais de 100 anos de atividade ininterrupta, e resgatar umamemória que tende a se perder. A banda sempre esteve à frente das festas cívicas,contagiando o público com marchas e hinos patrióticos, comandando desfiles escolares,impondo sua cadência e expressando através da música o sentimento de sua comunidade.Esta pesquisa surgiu da observação de que os trabalhos sobre bandas tinham como pontoprincipal a questão do ensino musical, mas não o valor pedagógico da música. Tambémnada havia sido escrito sobre a Banda de Música do Colégio Salesiano Santa Rosa. Assim,por meio da documentação histórica e da memória como suportes de reconstrução dahistória dessa banda secular, este trabalho lança um novo olhar sobre o tema.

Modeling and predicting the CBOE market volatility index

This paper performs a thorough statistical examination of the time-series properties of the daily market volatility index (VIX) from the Chicago Board Options Exchange (CBOE). The motivation lies not only on the widespread consensus that the VIX is a barometer of the overall market sentiment as to what concerns investors' risk appetite, but also on the fact that there are many trading strategies that rely on the VIX index for hedging and speculative purposes. Preliminary analysis suggests that the VIX index displays long-range dependence. This is well in line with the strong empirical evidence in the literature supporting long memory in both options-implied and realized variances. We thus resort to both parametric and semiparametric heterogeneous autoregressive (HAR) processes for modeling and forecasting purposes. Our main ndings are as follows. First, we con rm the evidence in the literature that there is a negative relationship between the VIX index and the S&P 500 index return as well as a positive contemporaneous link with the volume of the S&P 500 index. Second, the term spread has a slightly negative long-run impact in the VIX index, when possible multicollinearity and endogeneity are controlled for. Finally, we cannot reject the linearity of the above relationships, neither in sample nor out of sample. As for the latter, we actually show that it is pretty hard to beat the pure HAR process because of the very persistent nature of the VIX index.

Brazilian equity mutual funds: A general outlook based on performance

This dissertation main goal is to overview the Brazilian equity mutual funds returns. We find that active management is not effective for Ibovespa index, since Ibovespa active funds do not outperform the Ibovespa referenced funds. However, for IBrX index, active management do outperform the passive strategy. We found that Sustainable funds returns do not outperform the market, Endowment funds show poor performance, which could indicate strong regulation imposition over endowment funds portfolios. The size of a fund shows positive correlation to mean average returns and alphas. A fund’s lifetime is positively correlated to returns and to alphas, which could be related to more risk-taking by younger managers in order to pursue higher expected returns and, consequently, bigger inflows. Younger funds tend to have lower performance probably because, in taking more risks, they do not perform as expected. In addition, we find that the decreasing trend of the alpha evolution along the time is a sign of the industry decreasing returns of scale, which entails that managers have more difficulties to beat the market portfolio. Top 10s rankings show that funds appear more than once on the top 10s, which shows persistence of funds’ performance. Finally, concerning the deciles and quartiles rankings, the frequency of appearances changes among performance measures. There are measures which, when compared to others, strongly change the top and bottom for the decile and quartile members.

Analysts’ recommendations in Brazil: do they add value?

This paper examines the value of analysts’ recommendations in Brazilian Stock Market. We studied a sample of 294 weeks of recommendations make public by the best seller newspaper in Brazil with six different investment strategies and time horizons. The main conclusion is that it is possible to beat the Brazilian market indexes Ibovespa and IBrX following the analysts’ stock recommendations. The best strategies are buying only the recommended stocks, buying the recommended stocks whose target and market prices difference is bigger than 25% and lesser or equal than 50%. The performance of the six strategies is analyzed through the use of bootstrap and Monte Carlo techniques.
