We introduce a new hybrid approach to joint estimation of Value at Risk (VaR) and Expected Shortfall (ES) for high quantiles of return distributions. We investigate the relative performance of VaR and ES models using daily returns for sixteen stock market indices (eight from developed and eight...

An inherent problem with comparing and ranking competing Value at Risk (VaR) and Expected shortfall (ES) models is that they measure only a single realization of the underlying data generation process. The question is whether there is any significant statistical difference in the performance of...

The policy towards foreign direct investments in the EU countries is an integral part of their macroeconomic policy, with clearly defined development priorities, and the floats of the direct investments. These counties successfully implemented foreign direct investments into their long-term...

We investigate the performance of Value at Risk (VaR) models at measuring risk for WTI oil one-month futures returns. VaR models are used to calculate commodity market risk at extreme quantiles: 0.95, 0.99, 0.995 and 0.999 for both long and short trading positions. Widespread VaR models do not...

We propose an optimisation approach to determine the optimal decay factor in time weighted (BRW) simulation. The backtesting of the BRW simulation involving different decay factors together with a broad range of competing VaR models has been performed on a sample of seven stock indexes and two...

The author in this paper points out the reason behind calculating and using optimal trading quantity in conjunction with Markowitz's Modern portfolio theory. In the opening part the author presents an example of calculating optimal weights using Markowitz's Mean-Variance approach, followed by an...
