Information Release and Institutional Investment Behaviors
Based on H-S model,we compare,by expanding condition of information release,news watchersprofit with momentum and contrarian traders,and explain momentum trade behaviors under the condition of the reality in China.We build a theoretical model to prove: 1) When the speed of information transmitted to the price declines,the more dispersed information is,the weaker the impact of information on the total yield of the stock market is.And this weakened speed is rapidly accelerating with the spread of information;2) Because the institutions may not possess all information and the period in possession of information may not be too early,the deceleration spread of information makes information tradersand arbitrageursprofit space become very limited.
