Observation of the disconnection between real and financial spheres: the case of the Tunisian stock exchange market during the period 1969-2008

The strong volatility that characterized financial markets all over the word, these last years, leaves to think the existence of a disparity between stock prices and their fundamental values, which gives us the presumption of a disconnection between the real sphere and the financial one (Binswanger ( 1999, 2000, 2004 )). The purpose of this paper, is to focus on this possible disconnection by using the cointegration tests, to detect a possible equilibrium relation between the stock exchange returns and the real economic activity growth (measured by the GDP). The period of study lies between 1969 and 2008, according to an annual frequency of two series: the real yields (Stock Market Index return) and of GDP growth rates (real economic sphere indicator). To settle on the dynamics of short and long term between the stock exchange returns and the GDP growth, we used the Vector Errors Correction Model (VECM). Our results corroborate the existence of the disconnection between the two financial and economic series.
