Application of vine copulas to credit portfolio risk modeling
Geidosch, Marco; Fischer, Matthias - In: Journal of risk and financial management : JRFM 9 (2016) 2, pp. 1-15
In this paper, we demonstrate the superiority of vine copulas over conventional copulas when modeling the dependence structure of a credit portfolio. We show statistical and economic implications of replacing conventional copulas by vine copulas for a subportfolio of the Euro Stoxx 50 and the...

Does the assumption on innovation process play an important role for filtered historical simulation model?
Altun, Emrah; Tatlidil, Huseyin; Ozel, Gamze; … - In: Journal of risk and financial management : JRFM 11 (2018) 1, pp. 1-13
Most of the financial institutions compute the Value-at-Risk (VaR) of their trading portfolios using historical simulation-based methods. In this paper, we examine the Filtered Historical Simulation (FHS) model introduced by Barone-Adesi et al. (1999) theoretically and empirically. The main goal...

On setting day-ahead equity trading risk limits
Fuertes, Ana María; Olmo, Jose - In: Journal of risk and financial management : JRFM 9 (2016) 3, pp. 1-20
This paper investigates the information content of the ex post overnight return for one-day-ahead equity Value-at-Risk (VaR) forecasting. To do so, we deploy a univariate VaR modeling approach that constructs the forecast at market open and, accordingly, exploits the available overnight...

Quantification of VaR : a note on VaR valuation in the South African equity market
Mabitsela, Lesedi; Maré, E.; Kufakunesu, Rodwell - In: Journal of risk and financial management : JRFM 8 (2015) 1, pp. 103-126
The statistical distribution of financial returns plays a key role in evaluating Value-at-Risk using parametric methods. Traditionally, when evaluating parametric Value-at-Risk, the statistical distribution of the financial returns is assumed to be normally distributed. However, though simple to...

Predictors of excess return in a green energy equity portfolio : market risk, market return, value-at-risk and or expected shortfall?
Abraham, Rebecca; El-Chaarani, Hani; Tao, Zhi - In: Journal of risk and financial management : JRFM 15 (2022) 2, pp. 1-31
The rapid growth of electric vehicles, solar roofs, and wind power suggests that the potential growth in green equity investments is an emerging trend. Accordingly, this study measured the predictors of excess equity returns in a portfolio of global green energy producers, from 2010 to 2019....
