英文摘要:
In this paper, we study the mean-variance portfolio selection problem under partial information with drift uncertainty. First we show that the market model is complete even in this case while the information is not complete and the drift is uncertain. Then, the optimal strategy based on partial information is derived, which reduces to solving a related backward stochastic differential equation (BSDE). Finally, we propose an efficient numerical scheme to approximate the optimal portfolio that is the solution of the BSDE mentioned above. Malliavin calculus and the particle representation play important roles in this scheme.

中文摘要:
本文研究了具有漂移不确定性的部分信息下的均值-方差投资组合选择问题。首先,我们证明了即使在这种情况下,当信息不完整且漂移不确定时,市场模型也是完整的。然后,导出了基于部分信息的最优策略,该策略归结为求解相关的倒向随机微分方程(BSDE)。最后,我们提出了一种有效的数值格式来逼近最优投资组合,即上述BSDE的解。Malliavin微积分和粒子表示在该方案中起着重要作用。
