This study examines the characteristics of asymmetric volatility by industry in the Korean Stock Market. Also, we analyze the changes of the asymmetric volatility before and after the IMF financial crisis. Because accurate estimation and forecasting of volatility is essential for risk management, it is also important to understand the industrial characteristics of the asymmetric volatility. The main results of the empirical analysis with GARCH and GJR-GARCH model are as follow. At first, it exists the asymmetric volatility on both KOSPI and industrial stock indexes through the whole analytic period. Also, we find the GJR-GARCH is more suitable one than GARCH model forecasting volatility. Second, the asymmetric volatility in most of industrial stock indexes except financial industry is lower after IMF than before. And then the cause of this result is showed by that the asymmetric volatility of banking industry rises highly after the financial crisis.
