dc.description.abstract使用PCd模型,通过引入买卖价差、交易量、交易规模、委托指令流等交易信息变量探讨交易信息对投资者行为的影响。实证研究表明,买卖价差与期望交易持续期显著正相关,不支持EASlEy和O’HArA(1992)的观点。同时大规模的交易能够显著地延长交易持续期,而中等规模的交易能够减小交易持续期,证实了知情交易者的隐藏交易假说。指令流信息中的买卖申报数量也对交易持续期有显著的影响,上期买卖申报数量与本期交易持续期正相关。
dc.description.abstractThis paper studies the impact of trading information such as bid-ask spread,trading volume,transaction size,and order flow information on investor behavior.Empirical result of the PCD model shows that the bid-ask spread was significantly correlated with the expected duration,which is not consistent with Easley and O'Hara(1992).While large-scale trading is significantly correlated with longer duration,but medium-size transactions is often with shorter durations.It confirms the Stealth Trading Hypothesis of the informed traders.Order flow information such as the amount of trading quotes is positively correlated with duration.
