Market Risk and the Momentum Mystery
Kolari, James W. - 2019

The GJR GARCH(1,1) Process As Regularly Varying : Implications for Efficient Model Estimation and Risk Measurement
Prono, Todd - 2018
Linear GARCH(1,1) and GJR GARCH(1,1) processes are established as regularly varying, meaning their heavy tails follow a Power Law, under conditions that allow the innovations from the, respective, processes to be either symmetrically distributed or skewed. Skewness is considered a stylized fact...

Expected Profitability, the 52-Week High and the Idiosyncratic Volatility Puzzle
Khasawneh, Maher; McMillan, David G.; Kambouroudis, Dimos S - 2021
We investigate the joint ability of fundamental-based and market-based news to explain the anomalous underperformance of the stocks with high idiosyncratic volatility (high IVOL). An out-of-sample prediction of future profitability is adopted as a proxy for the fundamental–based news while...

Assessing portfolio vulnerability to systemic risk : a vine copula and APARCH-DCC approach
Mba, Jules Clement - In: Financial innovation : FIN 10 (2024), pp. 1-36
This study evaluates the sensitivity and robustness of the systemic risk measure, Conditional Value-at-Risk (CoVaR), estimated using the vine copula and APARCH-DCC models. We compute the CoVaR for the two portfolios across fve allocation strategies. The novel vine copula captures the complex...
