Ying Deng · Journal of Hefei University of Technology · 2003
Based on the MV portfolio selection theory,a research into the MV portfolio efficient frontier is carried out as the security number decreases or increases on condition that there exits a nonrisk yield security and the market is permitting short sale. The position variation of the tangent point is discussed with the TwoFund Separation Principle,and the benefit of the securities is analyzed and compared with the benefit which can be brought under the condition that there is a risk yield security and the market is permitting short sale. Then some practical results are obtained.
