Conditional Value-at-Risk Under Reward-Penalty Mechanism with Applications to Robust Portfolio Management
This paper develops robust portfolio selection models using worst-case CVaR with reward-penalty mechanisms and generalized uncertainty sets.
What it examines
The paper develops robust portfolio selection models that incorporate a reward and penalty mechanism to balance portfolio loss and downside risk under uncertain distributions. It uses worst-case CVaR, convex optimization, and mean-covariance uncertainty sets to derive optimal allocations for improved risk management.
What it concludes
The study shows that incorporating downside risk improves portfolio performance. Derived closed-form solutions and convex optimization formulations provide practical tools for robust portfolio management. Applications include finance and insurance risk management, with suggestions to explore additional uncertainty sets and risk measures in future research.
