This paper we backtest the FHS VaR model on three types of portfolios invested over a period of two years. The first set of backtests consists of LIFFE financial futures and options contracts traded on LIFFE. In the second ...
VaR Modelling on Long Run Horizons
(Kluwer Academic Publishers-Plenum Publishers, 2003-07)
The Value-at-Risk (VaR) criterion as a measure of portfolio's risk on long run horizons is considered. The method which makes possible to generate VaR estimates on longer horizons is suggested. The VaR estimation is based ...
Backtesting Derivative Portfolios with Filtered Historical Simulation (FHS)
(European Financial Management, 2002)
Filtered historical simulation provides the general framework to our backtests of portfolios of derivative securities held by a large sample of financial institutions. We allow for stochastic volatility and exchange rates. ...
Non parametric VaR Techniques. Myths and Realities
(Wiley Online Library, 2003-12-03)
VaR (value-at-risk) estimates are currently based on two main techniques: the variance-covariance approach or simulation. Statistical and computational problems affect the reliability of these techniques. We illustrate a ...
