论文题目：Betting Against Beta versus Betting Against Correlation: What Is the Difference?
论文摘要：We provide a decomposition framework to understand the difference between the betting against beta (BAB) strategy and the betting against correlation (BAC) strategy. The superior performance of BAB is driven by the market timing component, while the outperformance of BAC stems mainly from the cross-sectional components. However, contrary to the reasoning of a low-risk anomaly, low-correlation stocks are of small and illiquid firms with high volatility. Moreover, the BAC factor is fully subsumed by its betting against size (BAS) counterpart at each volatility quintile, signalling a size story. Therefore, BAC represents more of a high-risk investment strategy that is consistent with the implications of the funding liquidity theory. We then reconcile the seemingly contradictory fact that BAC is immune from investor sentiment while the low-correlation effect is a size story. Finally, we explore the portfolio implications of the decomposed market timing component.
