Standard approach in internationally diversified investment is the combination of asset allocation and index tracking. When the computation power and data availability was limited, this strategy was virtually the only workable approach to handle a large scale internationally diversified investment.Our approach, on the other hand is based upon stock-bond integrated model whose universe consist of individual stocks and bonds of many countries. We solve a large scale linear programming problem to determine an optimal portfolio and demonstrated that this approach perfectly outperforms the asset allocation/index tracking approach using the historical data of 3,400 asset of over 40 countries.The success depends upon (i)use of mean-absolute deviation model (instead of mean variance model), (ii)use of stock-bond integrated model and, (iii)availability of large scale data base.We are now convinced through three years effort that our approach can generate a stable and superior ex-post results by extending the model in such a way to cover assets of many other countries and risky bonds in addition to risk-free bonds.

国际多元化投资的标准方法是资产配置和指数跟踪相结合。在计算能力和数据可用性有限的情况下，这种策略实际上是处理大规模国际多元化投资的唯一可行方法。另一方面，我们的方法是基于股票-债券集成模型，其宇宙由许多国家的单个股票和债券组成。我们通过求解一个大规模线性规划问题来确定最优投资组合，并利用40多个国家3,400种资产的历史数据证明了该方法的性能优于资产配置/指数跟踪方法（而不是平均方差模型），（ii）使用股票债券一体化模型，（iii）大规模数据库的可用性。经过三年的努力，我们确信我们的方法可以产生一个稳定和上级的前-通过扩展模型，以这种方式来覆盖许多其他国家的资产和风险债券，以及无风险债券。
