“…Other two models satisfied this test in all of the markets for both confidence levels. Theoretically speaking, the extreme losses, that occurre prior to and during the backtesting period, can cause high VaR estimates and this way unconditional risk coverage is automatically achieved without taking into consideration the actual market risk (Radivojevic et al 2016a). This is why, for those markets in which the models passed the Kupiec's test, it is necessary to employ the Christofferson's test of conditional coverage, noting that because of the imperfections of this test, it is possible that the model which did not satisfy the unconditional coverage test, passed the test of conditional coverage, which does not mean that the VaR estimate is valid.…”

“…Although there is a widespread agreement about the use of VaR as the general measure of market risk and the economic loss that banks and other financial institutions may suffer due to exposure to the market risk (Radivojevic et al 2016a), there is no agreement on the best model to estimate VaR. All VaR models are based on assumptions which represent a compromise between the efficiency of implementation, on the one hand, and the statistical precision of market risk estimates on the other.…”
