| Tiivistelmä: | This paper investigates the presence of non-linear (hereafter as: n-l.) dependencies (as: n-l-dep./n-l-deps.) in stock returns (here as: rets.) for the Norwegian equity market. There are three n-l. models of asset rets. formulated applying ARMA-GARCH specifications for the conditional mean and variance equations. The paper aims to answer which model has the necessary characteristics, sufficient to account for most of the n-l-dep. In the Norwegian equity market, most of the n-l-dep. seems to be conditional heteroscedasticity. However, the most thinly traded assets still report significant n-l-dep. for all n-l. specifications. The results imply that the independence hypothesis can be rejected for all assets, portfolios and indices. |
