Cost-Sensitive Online Window Size Selection for Portfolio Management
Yi-Chen Liu, Chung-Han Hsieh
This paper investigates cost-sensitive online window size selection for portfolio management under changing market conditions. Specifically, we propose a two-level framework that c…
On Control of Drawdown: Robust Invariance and Optimality
Chung-Han Hsieh
Mitigating \emph{drawdown}, the decline in wealth from its running peak, presents a canonical problem in path-dependent risk control. In this paper, we develop a finite-horizon con…
Certified High-Dimensional Wasserstein Robust Portfolio Optimization
Chung-Han Hsieh, Rong Gan
We develop a certified, scalable approximation for high-dimensional Wasserstein distributionally robust portfolio optimization. For expected-utility maximization under order-one Wa…
Dynamic Weight Optimization for Double Linear Policy: A Stochastic Model Predictive Control Approach
Tan Chin Hong, Chung-Han Hsieh
The Double Linear Policy (DLP) framework guarantees a Robust Positive Expectation (RPE) under optimized constant-weight designs or admissible prespecified time-varying policies. Ho…
Sampled-Data Wasserstein Distributionally Robust Control of Multiplicative Systems: A Convex Relaxation with Performance Guarantees
Chung-Han Hsieh
This paper investigates the robust optimal control of sampled-data stochastic systems with multiplicative noise and distributional ambiguity. We consider a class of discrete-time o…
