英文摘要:
In the present work, the optimal portfolio minimizing the investment risk with cost is discussed analytically, where this objective function is constructed in terms of two negative aspects of investment, the risk and cost. We note the mathematical similarity between the Hamiltonian in the mean-variance model and the Hamiltonians in the Hopfield model and the Sherrington{Kirkpatrick model and show that we can analyze this portfolio optimization problem by using replica analysis, and derive the minimal investment risk with cost and the investment concentration of the optimal portfolio. Furthermore, we validate our proposed method through numerical simulations.

中文摘要:
在本文中,分析讨论了最小化投资风险和成本的最优投资组合,其中该目标函数是根据投资的两个消极方面,即风险和成本来构造的。我们注意到平均方差模型中的哈密顿量与Hopfield模型和Sherrington模型中的哈密顿量之间的数学相似性{Kirkpatrick模型,表明我们可以用复制分析来分析这个投资组合优化问题,并得出最优投资组合的最小投资风险和投资集中度。此外,我们通过数值模拟验证了我们提出的方法。
