Academic literature on the topic 'Jegadeesh and Titman'

Since the late 1980’s academicians have confirmed the presence of various forms of return regularities in stock returns. Two most well-known return regularities are contrarian and momentum profits. This paper – using monthly data for the period 2000 through 2016 – examines the presence of both contrarian profits and their sources in the Jordan stock market. The paper uses the methodology of Lo and MacKinlay (1990) and Jegadeesh and Titman (1995) to examine the presence of contrarian returns as well as the sources of such returns. Unlike other emerging markets where strong contrarian profits are found, Jordan market shows relatively weaker presence of contrarian profits. Moreover, time-series pattern – which is related to specific factors, is considered the main source of contrarian profits.

This paper tests the effectiveness of the momentum strategy for different time horizons between April 2013 and March 2020 and its sources in the Tunisian stock market. The findings display that, employing the methodology of Jegadeesh and Titman (1993), momentum strategy for all time horizons are positive and statistically significant. In the explanation section of the momentum effect, it is found that the momentum is not an illustration of the January effect and that both models (Capital Asset Pricing Model and the model of Fama and French (1993)) are unable to fully capture the profit of momentum strategy. However, we find that trading costs in the form of quoted spread eliminate the statistical significance of the momentum return. Therefore, an investor can’t make a profit by exploiting the momentum strategy in the Tunisian context.

This paper examines the behavioral bias in Tunisia, a country with a small stock market in terms of capital, but surprisingly dynamic in comparison to other emerging markets. Our study is consistent with Jegadeesh & Titman (1993)’ approach as presented to highlight an analysis of such reversal phenomena of portfolio returns, and provides explanatory factors to the so-called market trends reversal. The empirical investigation is based on a weekly database for a period from January 2002 to January 2013 related to stock prices and index values of market capitalization (TUNINDEX). The empirical test demonstrates the existence of winner-loser phenomenon in accordance with over-reaction hypothesis stating that portfolios with the worst past performance outperform, during the subsequent periods, those having produced best past performance and vice versa.

Purpose – The purpose of this paper is to investigate the momentum phenomenon in two market segments of the Chinese stock market – the Class A share market and Class B share market over time period spanning from January 1996 to December 2010. Design/methodology/approach – The authors largely follow Jegadeesh and Titman (1993) paper; the authors decompose the momentum returns following the procedure first proposed by Jegadeesh and Titman (1995). In addition, a liquidity factor (Pastor and Stambaugh, 2003) and a share ownership factor (Wang and Xu, 2004) are incorporated in the procedure to gauge the contribution of liquidity and the dynamics of share ownership towards the momentum returns, respectively in the two segments of the Chinese stock market. Findings – The authors find compelling evidence showing distinctively different momentum phenomena exist in the two market segments of the Chinese stock market. Specifically, the momentum phenomenon is more pronounced in the Chinese Class A share market compared to those found in the Chinese Class B share market. Through decomposing the momentum returns, the authors find evidence showing the dismal momentum returns observed in the Class B share market can be attributed to markedly weakened contributions of the liquidity factor and the share ownership factor. Research limitations/implications – Relatively short sample time horizon compared to the most of major financial markets such as USA and UK. The number of B shares has been rather limited. Practical implications – Subsequent to the opening of the Chinese Class B share market to domestic investors in 2001 and the opening of the Chinese Class A share market to qualified foreign institutional investors (QFII) in 2003, the empirical evidence found in this study provides a crucial reference point for domestic and foreign portfolio strategists in guiding them to form suitable portfolio strategies concerning investments in a nascent financial market such as the Chinese stock market, fraught with volatility and speculative trading behaviour. Social implications – It offers a comprehensive view of the momentum phenomenon in the Chinese Class A and B share markets over the sample period from January 1996 to December 2010. Second, the reasons behind the dichotomy of the momentum returns found in the two market segments were investigated through decomposing the momentum returns based on Jegdeesh and Titman’s (1995) method while incorporating three new explanatory factors – the liquidity factor, share ownership factor and the under reaction towards firm-specific news factor. Originality/value – A couple of extant papers have visited the topic before. yet this paper offers more comprehensive view on the existence of momentum premium in both Chinese Class A and B share markets and investigates the driving forces behind the subdued momentum returns observed in the B share market.
