Abstract:
|
Modeling the realized variance and covariance is an important component of understanding stock markets. We develop a multivariate stochastic covariance model based on the realized covariance estimated from higher frequency pricing data. Our model includes realized estimates of beta, thereby capturing the individual contribution to our optimal portfolio when considering a basket of stocks. Our methods will take into account the potential for extreme values across markets. We will apply our methods to the natural gas futures market of North America.
