| 摘 要： | 将上海证券交易所上市交易的股票分成十组,选取其中的极大和极小市值组合,采用向量自回归模型(VAR)分析收益、波动及日内买卖不平衡对大盘股和小盘股流动性的动态影响以及两类股票流动性的相互影响。实证结果表明,大盘股和小盘股的流动性存在着显著的正相关关系,且在同期都受到收益和波动的影响。两个组合的流动性不存在显著的领先——滞后关系,它们对前期的收益、波动和买卖不平衡变化存在不同的反应模式。

| Abstract: | This article creates 10 portfolios based on market capitalization of all stocks listed on the Shanghai Stock Exchange(SSE) and explores the dynamic reactions of liquidities of the two extreme portfolios,the largest cap portfolio and the smallest cap portfolio,to return,volatility and daily order imbalance in a Vector Autoregressive(VAR) framework.The empirical results show that there is significant positive correlation between liquidities of large cap stocks and small cap stocks,which are both affected by r... |
