الملخص EN

Abushammala, (2011) states that the most studies consider small capitalization stocks are less efficient, while large capitalization markets are efficient.

In last the two decades most of the previous studies depended on the hypotheses of normality and random walk (Irfan, Irfan & Awais, 2010; Gimba, 2010; Riaz, Hassa & Nadim, 2012; Zahid, Ramazan & Ramazan,2012; Patel, Radadia & Dhawan, 2012; Kumar & Singh, 2013) in order to understand the behavior of stock prices.

Also, trading strategies have to beplanned by individual or institutional investors taking into account the case in which the prices are characterized by random walks.

In addition, when the stock market is not efficient, this means investors can predict the future prices and generate abnormal profits based on historical prices and technical analysis (Haroon, 2012; Jethwani & Achuthan, 2013; Kumer & Singh, 2013).
