dc.description.abstract-translatedVaR and CVaR are effective quantitative measurements of market risk. These measures can quantify the risk of unexpected changes within a given period. In this paper, we examine the market risk of the US stock market index S&P 500 and cryptocurrencies bitcoin and ripple. The returns of these three instruments are approximated using normal inverse Gaussian distribution and alpha stable distribution. For comparison, the normal distribution is also included. Subsequently, the VaR99 and CVaR97.5 values corresponding to four candidate distributions are calculated for these instruments. We also analyze the ability of theoretical distributions to approximate the left tail behavior of stock market index returns. It turns out that the normal distribution is not suitable for this purpose. Furthermore, it appears that CVaR97.5 is higher (in absolute value) for all indices than the corresponding VaR99 which may require higher need for economic capital which banks should allocate.en
