Robust portfolio models help manage investments in uncertain markets. The WOmega model outperformed two CVaR-related models in controlling downside risk and generating higher market values. It considers transaction costs and short-selling, making it a strong choice for a wide range of assets. In a study using daily returns over 10 years, the WOmega model consistently showed better performance in balancing return and risk compared to the other models. This means it can help investors protect their investments better while aiming for higher returns.
