Abstract
Volatility is the measure of how far the current price of an asset deviates from its average past prices. Greater the deviation, greater the volatility. It indicates the strength or conviction behind a price movement. Stock market volatility is the function of the arrival of positive and negative market information. Pricing of securities is supposed to be dependent on the volatility of each asset. Matured / developed markets continue to provide over long period of time high returns with low volatility. Emerging markets, except India and China exhibit low returns. The exponential growth in the Asian derivatives markets necessitated the need to test whether the Asian market indices are more volatile or not. The study finds an evidence of time varying volatility, which exhibits clustering, high persistence and predictability for almost all the Asian market indices in the sample. With this background the present paper investigates the dynamic behavior of stock returns of ten market indices from Asian countries, using symmetric GARCH (1,1) model for a period of one year from January 2006 to December 2006.
