During the study period, selected indices’ daily returns have shown non-normality, homogeneity of mean and variance. Runs test for randomness, Auto-Correlation Function (ACF) and Augmented Dickey-Fuller (ADF) Unit root test have indicated statistically significant results and accentuates that the selected broad based market indices remained weak-form inefficient during the study period.
