Research on Optimal Investment Portfolio of Enterprise Annuity under Investment Constraints ()
ABSTRACT
Using Markowitz’s
mean-variance model, this article measured the yields and risks of the four
major investment instruments under the premise of different investment
portfolios in the current enterprise-annuity-investment constraints.
Finally, under the existing annuity investment constraints, this paper found
that 1) corporate bonds are better than government bonds from the security and
profitability of the enterprise annuity portfolio, 2) the combination of two or
more investment instruments can more diversify risks, 3) stock investment needs to be selected in the
portfolio, the higher the proportion of stock investment, the greater the yield
of the enterprise annuity portfolio.
