摘要

我发现Fama-French规模和价值因素中大约30%的价格波动是由相关资金流驱动的非基本面价格压力，这导致价格波动随着时间的推移而恢复。这真的是基于需求的价格压力吗?我表明，价格效应只发生在共同基金进行交易的时期，这一事实很难用传统机制(如未观察到的投资者偏好变化)来解释。估计的价格弹性也与其他研究一致。总的来说，我的研究结果表明，相当一部分规模和价值因素的变动并不代表经济风险。

What Drives the Size and Value Factors?

I find that approximately 30% of price fluctuations in the Fama-French size and value factors are nonfundamental price pressures driven by correlated fund flows, which generate price movements that revert over time. Is this really demand-based price pressure? I show that the price effects happen exclusively in periods when mutual funds place trades, a fact that is difficult to explain using traditional mechanisms such as unobserved investor preference changes. The estimated price elasticity is also consistent with other studies. Overall, my findings show that a sizable fraction of size and value factor movements do not represent economic risk.

期刊介绍： The Review of Asset Pricing Studies (RAPS) is a journal that aims to publish high-quality research in asset pricing. It evaluates papers based on their original contribution to the understanding of asset pricing. The topics covered in RAPS include theoretical and empirical models of asset prices and returns, empirical methodology, macro-finance, financial institutions and asset prices, information and liquidity in asset markets, behavioral investment studies, asset market structure and microstructure, risk analysis, hedge funds, mutual funds, alternative investments, and other related topics. Manuscripts submitted to RAPS must be exclusive to the journal and should not have been previously published. Starting in 2020, RAPS will publish three issues per year, owing to an increasing number of high-quality submissions. The journal is indexed in EconLit, Emerging Sources Citation IndexTM, RePEc (Research Papers in Economics), and Scopus.
