文档介绍：1 Value and Momentum Everywhere Clifford S. Asness, Tobias J. Moskowitz, and Lasse H. Pedersen ? First Version: March 2008 This Version: February, 2009 Abstract Value and momentum ubiquitously generate abnormal returns for individual stocks within several countries, across country e quity indices, government bonds, currencies, modities. We study jointly the globa l returns to value and momentum and explore mon factor stru cture. We find that value (momentum) in one asset class is positively correlated with value (momentum) in other asset classes, and value and momentum are negatively correlated within and across asset classes. Liquidity risk is positively related to value and negatively to momentum, and its importance increases over time, particularly following the liquidity crisis of 1998. These patterns emerge from the power of examining value and momentum everywhere simultaneously and are not easily detectable when examining each asset class in isolation. ?

Introduction Two of the most studied capital market phe nomena are the relation between an asset’s return and the ratio of its “long-run”(or book) value relative to its current market value, termed the “value” effect, and the
