在读<The Intelligent Investor>,第七章<Portfolio Policy for the Enterprising Investor:The Positive Side>结尾处有一句话没读懂,还请高手指点:It is a basic characteristic of a primary or leading company that a single detached share is ordinarily worth as much as a share in a controlling block.In secondary companies the average market value of a detached share is substantially less than its worth to a controlling owner.非常感谢~
