英文摘要:
  We prove that the Omega measure, which considers all moments when assessing portfolio performance, is equivalent to the widely used Sharpe ratio under jointly elliptic distributions of returns. Portfolio optimization of the Sharpe ratio is then explored, with an active-set algorithm presented for markets prohibiting short sales. When asymmetric returns are considered we show that the Omega measure and Sharpe ratio lead to different optimal portfolios.

中文摘要:
我们证明了在评估投资组合绩效时考虑所有时刻的Omega测度等价于联合椭圆收益分布下广泛使用的Sharpe比率。然后探讨了夏普比率的投资组合优化,并针对禁止卖空的市场提出了一种主动集算法。当考虑非对称收益时,我们证明了欧米茄测度和夏普比率会导致不同的最优投资组合。
