As inter-relações envolvendo as principais bolsas de valores mundiais: um enfoque utilizando séries temporais

Abstract

Investing financial resources on the stock exchange undergoes analysis by several stock markets. For this reason, this paper aims primarily to analyze the existing inter-relations between the stock markets of the G7 (the seven most economically-developed countries) and the BRICs (the current four emerging economies). For this purpose, were used time series of the main indexes for surveyed stock exchanges, whose data were collected from January 2003 to September 2008, as well as econometric methods involving Granger’s causality theories and predictability among markets, resulting from the use of the Autoregressive Vector Model. The results show relations between several stock markets. They also show that: the indexes of the G7 countries help predict BRIC index values; that there is an open exchange between the Chinese market and others markets; and that the German market, represented by the Frankfurt stock exchange through DAX30 index, has significant influence in other stock exchanges.
