One of the capital market anomalies and exceptions in finance are momentum. Momentum strategies are applied to use serial correlation available in market and securities returns. In these strategies investors can earn excess return as follow: buying winner stocks in the past and selling loser stocks in the past. In this study, we are going to explore the profitability of price and earning momentum strategies in Tehran Stock Exchange. Also, the impact of factors such as abnormal return, standardized unexpected earnings, price to earnings per share ratio, book value to market value ratio and company’s size on return of these strategies are investigated 1383 to 1387. This research based on four hypothesizes which most important of these hypothesizes is: by using price and earning momentum strategies in Tehran Stock Exchange, an investor can earn excess return. Results indicate that price momentum strategy in 3-month, 6-month and one-year time periods in Tehran stock exchange is profitable. However, earnings momentum strategy only in 3-month and 6-month time horizons is profitable. Testing third hypothesis show that in 3-month and 6-month time horizons, the model’s independent variables justify the excess return of price momentum strategy but in one-year time period, except for independent variables, other factors affect the excess return. In forth hypothesis, significant relationship between price and earnings momentum strategies in 3-month and 6-month time horizons is accepted but in one-year period, there is no significant relation between them.
