ADRs under momentum and contrarian strategies

Given the recent growth in the American Depositary Receipts (ADRs) and the current general climate of globalization in world equity exchanges, this paper investigates the ADRs as a distinct group of stocks within the framework of momentum and contrarian strategies. It considers the entire body of the level III ADRs from January 1982 to December 2005 and provides an analysis of their performance under various momentum and contrarian strategies. The methodology that is employed draws upon and is an extension of Lo and Mackinlay [Lo, Andrew W. and A. Craig MacKinlay, 1990. When are contrarian profits due to stock market overreaction? Review of Financial Studies, v3 (2), 175-206.] and Jegadeesh and Titman [Jegadeesh, Narasimhan and Sheridan Titman, 2001. Profitability of momentum strategies: An evaluation of alternative explanations, Journal of Finance, v56 (2, Apr), 699-720.]. The results indicate considerable support for the presence of the momentum and contrarian strategies in the ADRs market. The profitability of such strategies obviously runs counter to the efficient market hypothesis. These issues are elaborated upon and suggestions for further research are offered.
