标题[问题] 为何是负相关?
时间Tue Jan 22 16:41:29 2008
最近在看一篇财务的实证文章
里面有一小段说道:
Several researchers have argued that institutional investors are informed
investors. This implies a negative correlation between the level of
informational asymmetry and the level of institutional ownership.
我想请问
为什麽可以由"法人拥有内线"
推论到"法人持股比列越高(低)的个股,资讯不对称程度越低(高)"
看不出个所以然来?
感谢指教~~~
