This paper studies a robust portfolio choice problem with return predictability and price impacts in continuous time. Asset returns are modeled by some stochastic factors and trades incur both transient and permanent price impacts. Assuming ambiguity aversions toward asset returns and...

In this paper, we solve a continuous-time portfolio choice problem of an investor under a Markov jump linear system that effectively captures stochasticity in asset returns, price impacts, and market resilience. Specifically, the investor chooses his portfolio to maximize the expected excess...
