Bank characteristics effect on capital structure : evidence from PMG and CS-ARDL
Erülgen, Ahmet; Rjoub, Husam; Adalıer, Ahmet - In: Journal of risk and financial management : JRFM 13 (2020) 12/310, pp. 1-13
The main aim of this paper was to investigate the impact of bank characteristics on capital structure empirically. The study employed a panel data analysis, Pooled Mean Group (PMG) and Cross-Sectionally Augmented Autoregressive Distributed Lag (CS-ARDL) estimators were utilized, for the period...

Capital structure and bank profitability in Vietnam : a quantile regression approach
Le, Tu D. Q.; Nguyen, Dat T. - In: Journal of risk and financial management : JRFM 13 (2020) 8/168, pp. 1-17
We empirically investigate the impact of capital structure on bank profitability using a quantile regression method in … and bank profitability is only significant at the 90th quantile. This is the first study to conclude that the turning … point of capital ratio increases throughout the profitability distribution. Our findings thus suggest that a continuous …

Portfolios dominating indices : optimization with second-order stochastic dominance constraints vs. minimum and mean variance portfolios
Keçeci, Neslihan Fidan; Kuzmenko, Viktor; Uryasev, Stan - In: Journal of risk and financial management : JRFM 9 (2016) 4, pp. 1-14
The paper compares portfolio optimization with the Second-Order Stochastic Dominance (SSD) constraints with mean-variance and minimum variance portfolio optimization. As a distribution-free decision rule, stochastic dominance takes into account the entire distribution of return rather than some...

Best-arm identification using extreme value theory estimates of the CVaR
Troop, Dylan; Godin, Frédéric; Yu, Jia Yuan - In: Journal of risk and financial management : JRFM 15 (2022) 4, pp. 1-15
We consider a risk-aware multi-armed bandit framework with the goal of avoiding catastrophic risk. Such a framework has multiple applications in financial risk management. We introduce a new conditional value-at-risk (CVaR) estimation procedure combining extreme value theory with automated...

Portfolio optimization on multivariate regime-switching garch model with normal tempered stable innovation
Peng, Cheng; Kim, Young Shin; Mittnik, Stefan - In: Journal of risk and financial management : JRFM 15 (2022) 5, pp. 1-23
This paper uses simulation-based portfolio optimization to mitigate the left tail risk of the portfolio. The contribution is twofold. (i) We propose the Markov regime-switching GARCH model with multivariate normal tempered stable innovation (MRS-MNTS-GARCH) to accommodate fat tails, volatility...

CVaR regression based on the relation between CVaR and mixed-quantile quadrangles
Golodnikov, Alex; Kuzmenko, Viktor; Uryasev, Stan - In: Journal of risk and financial management : JRFM 12 (2019) 3/107, pp. 1-22
A popular risk measure, conditional value-at-risk (CVaR), is called expected shortfall (ES) in financial applications. The research presented involved developing algorithms for the implementation of linear regression for estimating CVaR as a function of some factors. Such regression is called...

CoCDaR and mCoCDaR : new approach for measurement of systemic risk contributions
Ding, Rui; Uryasev, Stan - In: Journal of risk and financial management : JRFM 13 (2020) 11/270, pp. 1-18
Systemic risk is the risk that the distress of one or more institutions trigger a collapse of the entire financial system. We extend CoVaR (value-at-risk conditioned on an institution) and CoCVaR (conditional value-at-risk conditioned on an institution) systemic risk contribution measures and...

Uncertainty and risk in the cryptocurrency market
Almeida, Dora; Dionísio, Andreia Teixeira Marques; … - In: Journal of risk and financial management : JRFM 15 (2022) 11, pp. 1-17
Cryptocurrency investments are often perceived as uncertain and risky. In this study, we assessed if this is indeed the case, using a sample of seven cryptocurrencies and considered a period that encompassed the first real global shock in the life of these relatively new financial assets, the...
