- Description
- The study is an examination of weak form market efficiency (EMH) in BRICS equity markets using weekly data spanning from 2005 to 2018. The study makes use linear as well as nonlinear unit rot tests, that is, the ADF and KSS tests respectively. For more robust results, the study uses the Integer Flexible Fourier Function (IFFF) and the Fractional Frequency Flexible Fourier Function (FFFFF) to account for smooth structural breaks. The study investigates the full sample period and splits the empirical data into three sub-samples corresponding to the period succeeding the global financial crisis, the BRICS summits and the BRICS Development Bank (BDB). This study, to the best of our knowledge, is the first to investigate the efficiency in the BRICS stock markets using a combination of the specified series of unit root tests. Moreover, there are no prior studies that have examined these markets for the sub-samples mentioned above. Our empirical results point us to convincing evidence of weak form inefficiency as the majority of the results reject the null hypothesis of a unit root.
