Abstract EN

The study aims to estimate the sharp deviations that occur in the international financial markets in a sample of the developed international stock exchanges, in which several shocks and financial crises emerged during the period (2008-05/2021), by measuring the values of fluctuations, and comparing them with the level of actual fluctuations resulting from the events The study concluded that the estimated results do not represent the level of real fluctuations witnessed by the sample of the studied stock exchanges, which contributed to enhancing the levels of instability of financial markets due to misleading estimates and the realization of systemic risk several times during the study period (crisis), which led to the difficulty of controlling macro financial stability when major shocks occur.
