英文摘要:
The question addressed in this paper is the performance of the optimal strategy, and the impact of partial information. The setting we consider is that of a stochastic asset price model where the trend follows an unobservable Ornstein-Uhlenbeck process. We focus on the optimal strategy with a logarithmic utility function under full or partial information. For both cases, we provide the asymptotic expectation and variance of the logarithmic return as functions of the signal-to-noise ratio and of the trend mean reversion speed. Finally, we compare the asymptotic Sharpe ratios of these strategies in order to quantify the loss of performance due to partial information.

中文摘要:
本文讨论的问题是最优策略的性能,以及部分信息的影响。我们考虑的背景是随机资产价格模型,其中趋势遵循不可观察的Ornstein-Uhlenbeck过程。我们主要研究在完全或部分信息下具有对数效用函数的最优策略。对于这两种情况,我们都提供了对数回报的渐近期望和方差,作为信噪比和趋势均值回归速度的函数。最后,我们比较了这些策略的渐近夏普比率,以量化由于部分信息而导致的性能损失。
