    Evidencia de volatilidad agrupada en el mercado accionario Ecuatoriano: aplicación de un modelo Igarch para el índice Ecuindex
    (Universidad de Cuenca, 2017-01) Covri Rivera, Daniele
    The present research tries to develop a variant of the GARCH model for the Ecuadorian index stock market Ecuindex. The data are taken daily and cover a time horizon of more than 13 years. Because the sum of the parameters in the variance equation turns out to be exactly 1, therefore, an IGARCH model (1,1) is implemented. The aim is to understand if volatility is clustered and, secondly, the purpose is to measure the risk of the Ecuadorian stock market. These results may be relevant for further research looking at predictions using financial derivative instruments or for measuring the market risk of portfolios.
