If stock market is efficient, one cannot generate abnormal profit. The objective of the present study is to test the weak market efficiency of Indian Stock Market. The stock indices are Sensex and Nifty. The daily adjusted closing price of these two companies is collected from October 8, 2012 to October 5, 2018. The variance ratio test was employed to test the weak market efficiency. The result revealed that Indian market is not efficient. It is found that technical analysts can generate excess return in Indian Stock Market both in Sensex and Nifty.
Keywords: variance ratio test; market efficiency; unit root test; random walk model.
