Stochastic GARCH dynamics describing correlations between stocks
journal contribution
posted on 2015-08-19, 15:36 authored by G. Prat-Ortega, Sergey SavelievSergey SavelievThe ARCH and GARCH processes have been successfully used for modelling price dynamics such as stock returns or foreign exchange rates. Analysing the long range correlations between stocks, we propose a model, based on the GARCH process, which is able to describe the main characteristics of the stock price correlations, including the mean, variance, probability density distribution and the noise spectrum.
