In this paper, we study the Value-at-Risk estimation using bootstrap. Specifically, VaR was estimated by using bootstrap return data based on CCC-GARCH model. In real data analysis, we constructed a portfolio using KOSPI 200 and S&P500 stock price index and compared VaR with the bootstrap method and the exponentially weighted moving average (EWMA) method on the assumption of normal distribution. The backtesting results show that VaR estimation using bootstrap method is more efficient than VaR estimation using EWMA method.
