Abstract

This paper examines the forecasting ability of the non-linear specifications of the market model. We propose a conditional Two-moment market model with a time-varying systematic covariance (beta) risk in the form of a mean reverting process of the state space model via Kalman Filter algorithm. In addition, we account for the systematic component of co-skewness and co-kurtosis by considering higher moments. The analysis is implemented using data from the stock indices of several developed and emerging stock markets. The empirical findings favour the time-varying market model approaches which outperform linear model specifications, both in terms of model fit and predictability. Precisely, higher moments are necessary for datasets which involve structural changes and/or market inefficiencies which are common in most of the emerging stock markets.
