Risk model validation for BRICS countries: a value-at-risk, expected shortfall and extreme value theory approach
The authors of this paper employ value-at-risk (VaR) and expected shortfall (ES) as risk measures to assess the competency of several volatility models, based on the stock indexes of the BRICS countries (Brazil, Russia, India, China and South Africa)…
