The influence of the tag-along rights in the value of companies: an event study of the effects on the market and service companies

The aim of this work is to check the effect of granting tag-along rights to stockholders by analyzing the behavior of the return of the stock. To do so we carried out event studies for a group of 21 company stocks, divided into service provider companies and others, who granted this right to their stockholders after Law 10,303 was passed in October, 2001. In the test we used two models for estimating abnormal returns: adjusted to the market and adjusted to the risk and market. The results of the tests we carried out based on these models did not capture abnormal returns (surpluses), telling us that the tag-along rights did not affect the pattern of daily returns of the stocks of companies traded on BOVESPA (The Sao Paulo Stock Exchange). We did not expect this result because of the new corporate governance practices adopted by companies in Brazil.

The Sao Paulo stock exchange and the economic stabilization

The inflationary stabilization recently observed in Brazil brings a lot of changes in all aspects of the country’s economic life. In this work we look at the impacts on the stock market, specifically at Bovespa - the São Paulo Stock Exchange. We analyze the leading variables and statistics that describe Bovespa’s behavior, such as volatility and systematic risk, comparing the four years preceding and the four years after 1994, when the Real Plan was implemented. In order to eliminate exogenous influences, we use control series made with international Stock Exchanges Indexes. The results show that after 1994 there was reduced volatility, increased trade volume, reduced efficiency of the Bovespa Index and no changes in systematic risk.

Does active management add value?: the Brazilian mutual fund market

Does active management add or destroy value? With a sample of 699 with four different main categories: stocks, fixed income, hedge and exchange rate mutual funds we conclude that the active management add value to investors in stocks and hedge funds. But in fixed income mutual funds the evidence is against the active management. We also analyze the determinants of significant alphas. For stocks and hedge funds the evidence suggests that old, big and active funds generate biggest alphas. In fixed income funds the evidence is not clear, only a positive relationship between size and alphas could be found.

Exchange rate management techniques

This briefing note addresses the question: What revisions of financial regulation and financial governance in Brazil are necessary to support Brazilian development? What’s in place and what’s missing? The focus here is a dimension of financial regulation and governance: the regulation of capital flows and of exchange rate operations. The arguments are organized in the following manner. In the next section, we summarize the impacts of th crisis on the emerging-market economies and on the regulation of the international monetary and financial system. The third section discusses the post-crisis dilemmas faced by these economies. Finally, the fourth section presents some policy recommendations for Brazil.
