Momentum and Price Momentum Components: Evidence from 23 Jordanian indices

Article January 26, 2017

The aim of this paper is to investigate whether there is the momentum effect across 23 indices-level anomaly in Amman Stock Exchange (ASE). This study also compares and contrasts the momentum strategy with both early-stage and late-stage momentum strategies. By using a sample of 23 Jordanian indices for the period from 2005 to 2015, this paper provide economically large momentum profits over the past 6, 9 and 12 months tend to outperform in the future. In addition, this study provides convincing evidence that late-stage momentum strategy consistently generates stronger profits than does the traditional momentum strategy. Although the CAPM model can explain the momentum profits, late-stage momentum strategy cannot completely explained by the CAPM model.

The Firm Value Effect: Evidence from Egypt

Article August 17, 2016

This paper investigates for a value effect in Egyptian firm returns using three different ways to determine value by sorting firms based on their past long-term returns (long-term contrarian), the book-to-market ratios (BE/ME), and the percentage changes in their BE/ME ratios (change). These three strategies are approaches commonly used to measure for value effect. Using sample period from January 1997 to April 2014, this study provides a strong evidence of an inter-firm value effect with three measures. The long-term return contrarian and BE/ME, produce significant abnormal raw returns of 2.18% and 2.01%, respectively. On the other hand, the percentage changes in their BE/ME provides weakly significant profits of 1.08% per month. This paper also shows that the value profits generated by all three alternative value strategies in Egyptian stock market can be explained by three-factor model.
