Modeling univariate volatility of stock returns using stochastic GARCH models:Evidence from 4-Asian markets

This paper applies the Generalized Autoregressive Conditional Heteroscedasticity (GARCH) models to the financial time series (stock index returns) in four Asian markets namely; Kuala Lumpur Composite Index (KLCI) of Malaysia, the Straits Times Index (STI) of Singapore, Nikkei Indices (N225) of Japan...
