To test the market efficiency, the study considers the daily closing prices of 13 and 10 sectoral indices of Bombay Stock Exchange (BSE) and National Stock Exchange (NSE), respectively, along with the BSE SENSEX and CNX NIFTY. The empirical results provide evidences for the absence of the weak-form efficiency and random walk hypothesis in the case of all sectoral indices of NSE and BSE along with the CNX NIFTY and BSE SENSEX. Thus, trading strategies can be formulated by investors to gain abnormal returns in the Indian stock markets. And it can be inferred that there is a possibility of earning extra income on account of inefficiency in these market portfolios ER -
