Risk Management under Omega Measure
نویسندگان
چکیده
We prove that the Omega measure, which considers all moments when assessing portfolio performance, is equivalent to the widely used Sharpe ratio under jointly elliptic distributions of returns. Portfolio optimization of the Sharpe ratio is then explored, with an active-set algorithm presented for markets prohibiting short sales. When asymmetric returns are considered, we show that the Omega measure and Sharpe ratio lead to different optimal portfolios.

Modifications of the Omega ratio for decision making under uncertainty
The Omega ratio (Ω-ratio) was proposed by Shadwick and Keating in 2002 as a performance measure applied to rankings of assets, portfolios or funds. It involves partitioning returns into loss and gain below and above a given threshold. The original version was designed for decision making under risk (probabilities completely known), but recent research has shown that this measure can be adapted ...
متن کاملRisk Management and Portfolio Selection Using α-Stable Regime Switching Models
This article tries to enhance traditional distribution paradigms for modelling asset returns by considering an α-stable regime-switching model. Our approach is to perform an empirical test of the α-stable regimeswitching model against other common methods in two settings: in risk management and in portfolio selection. Our empirical study will show that the model is better suited than Gaussian a...

Design of a logistics network in proper way provides a proper platform for efficient and effective supply chain management. This paper studies a multi-period, multi echelon and multi-product integrated forward-reverse logistics network under uncertainty. First, an efficient complex mixed-integer linear programming (MILP) model by considering some real-world assumptions is developed for the inte...
متن کاملRelationship between Corporate Governance and Risk Management
Corporate governance of banks is one of the most important structures required by banks to maintain the health and stability of banks, which can play an important role in managing banks' risk. This paper examines the effect of corporate governance on liquidity risk management, credit risk management, and total bank risk management. We used board structure effectiveness, transparency, and respon...
متن کاملRisk measurement and Implied volatility under Minimal Entropy Martingale Measure for Levy process
This paper focuses on two main issues that are based on two important concepts: exponential Levy process and minimal entropy martingale measure. First, we intend to obtain risk measurement such as value-at-risk (VaR) and conditional value-at-risk (CvaR) using Monte-Carlo methodunder minimal entropy martingale measure (MEMM) for exponential Levy process. This Martingale measure is used for the...
