Stock markets stand as an important element within the financial system. Financial crises of 2008 showed that stock market crash influence the real economy. On the other hand, economic and financial globalization has created interdependency within national economies. The current research tends to measure risk exposure of the Visegrad stock markets (Czech Republic, Hungary, Poland and Slovakia). One of the indicators of the risk exposer of a financial assets is value at risk. In this study, value at risk is estimated using GARCH model in a dataset of almost three thousand working days per each stock markets. White noise process and ARIMA (1, 1) were applied to get more robust results. The worse stock index among Visegrad countries was identified SAX (Bratislava index, Slovakia) and the most promising one was BUX (Budapest index, Hungary). Value at risk is a useful tool that investors can use to analyze the performance of a share or market index in terms of risk exposure. Furthermore, it can be used even as an instrument to forecast the level of risk exposure an investor could face in the future.Internal Grant Agency of Univerzita Tomase Bati ve Zline [IGA/FaME/2019/002
