摘要

This paper demonstrates that the cross-sectional variation of liquidity commonality has increased over the period 1963-2005. The divergence of systematic liquidity can be explained by patterns in institutional ownership over the sample period. We document that our findings are associated with similar patterns in systematic risk. Our analysis also indicates that the ability to diversify systematic risk and aggregate liquidity shocks by holding large-cap stocks has declined. The evidence suggests that the fragility of the US equity market to unanticipated events has increased over the past few decades. (C) 2008 Elsevier B.V. All rights reserved.
