Dynamic mean-variance portfolio selection with no-shorting constraints and unknown investment opportunity sets
Xun Li, Yutian Wang, Xun Yu Zhou
We study continuous-time mean-variance portfolio selection with no-shorting constraints and unknown investment opportunity sets from a reinforcement learning (RL) perspective. The…

Solving Coupled Nonlinear Forward-backward Stochastic Differential Equations: An Optimization Perspective with Backward Measurability Loss
Yutian Wang, Yuan-Hua Ni, Xun Li
This paper aims to extend the BML method proposed in Wang et al. [22] to make it applicable to more general coupled nonlinear FBSDEs. We interpret BML from the fixed-point iteratio…
