Abstract

Trading shares of a country has the same or different characteristics as other countries. The characteristics of the market are a reflection of the character of investors who play a role in trading on the stock exchange. Although there are differences or similarities in character on a country's stock exchange, there is something experienced by all stock exchanges in various countries, namely the movement of stock price values and volumes in stock trading dynamically known as volatility. Volatility as a risk thatĀ  an investor must face in investing requires theĀ  ability to predict volatility so that the risk of loss borne by investors can be reduced. The volatility forecasting model with the Garch and E Garch methods is expected to be one of the investors' considerations in making rational investment decisions.
