Evaluation of Usefulness of Bl_Garch Models in Estimation of Value at Risk for the Index Wig20
Języki publikacji
Abstrakty
Wartość zagrożona (Value at Risk, AaR) jest obecnie standardowąmiarą, zapomocą której analitycy finansowikwalifikują ryzyko rynkowe. W niniejszym artykule prognozowany jest VaR dla indeksu WIG20, przy wykorzystaniu oszacowań zmienności uzyskanych za pomocą modeli AR-GARCH oraz modeli dwuliniowych BL-GARCH. (fragment tekstu)
Value at risk (VaR) is a standard measure used to quantify financial market risk. Precise forecasts of VaR are a very important element of risk management process. Calculations of VaR for the stock index WIG20 presented in this paper are based on the volatility estimates provided by BL-GARCH and AR-GARCH models. Our finding is that in the case under scrutiny the volatility forecasts obtained by more complicated BL-GARCH models did not result in significantly more accurate VaR estimates. (original abstract)
