Abstract: This study investigates weak form efficiency for 4 stock and 6 bond market return under the Johannesburg Stock Exchange (JSE) using monthly data spanning from 2002 to 2016. Our empirical strategy consists of using both individual and panel based unit root testing procedures. Moreover, we split our empirical data into two sub-samples corresponding to periods before and periods subsequent to the global financial crisis. Our empirical results point to an overwhelming evidence of weak form efficiency as the integration test fail to produce convincing evidence of unit root behaviour amongst the observed time series. The study thus confirms the efficiency of equities and debt markets in South Africa in light of the global financial crisis.
