The iid property of the model’s residuals is a crucial criterion for assessing the fit of the model to the data. GARCH-class models are the most commonly used nonlinear models in financial econometrics. In this paper various uni- and multivariate GARCH-class models were applied to selected...

The purpose of this study is to test the weak form efficiency within framework of the random walk model by using price movements of BIST-100 Index and to evaluate forecasting performance of investors in Turkish stock market. Whether investors can earn excess returns or not has been decided with...

The study examines the weak form efficiency in stock returns for the economies of Brazil, Russia, India and China (BRIC), from January 2000 to December 2010. The study uses LM unit root test with one and two structural breaks as given by Lee and Strazicich (2003, 2004), along with the recently...

This paper suggests a systematic approach to studying predictability and nonlinear dependence in the context of the Indian stock market, one of the most important emerging stock markets in the world. The proposed approach considers nonlinear dependence in returns and envisages appropriate...

This article validates the chaotic behavior in the Argentinean, Brazilian, Canadian, Chilean, American, Peruvian and Mexican Stock Markets using the MERVAL, BOVESPA, S&P TSX COMPOSITE, IPSA, IGPA, S&P 500, DOW JONES INDUSTRIALS, NASDAQ, IGBVL and IPC Stock Indexes respectively. The results of...

Using the UK as the base country, this study investigates the nature of the inherent non-stationarity of the major bilateral real exchange rates for the post Bretton Woods era. Non-linearity is shown to be pervasive in both the changes in the real exchange rates and the residuals of the ADF...

The aim of the study is nonlinearity test of ISE – 100 returns. The most usedly nonlinearity test of BDS test is applied. Data is obtained from the Central Bank of Turkey. Return data is calculated by the difference of natural logarthim of daily closing value. The data has 4352 observations,...

Capital market efficiency of emerging markets has been investigated widely in recent years. But to-date the empirical results remain inconclusive because most empirical studies use empirical tests, which are designed to detect linear structure in financial time series. However, recent...
