The Kuwait stock exchange index is examined for evidence of a day-of-the-week effect. A nonlinear GARCH(1,1) model provides a good explanation of the data and allows identification and modelling of the day-of-the-week effect.

The validity of the weak form of the efficient markets hypothesis (EMH) is tested for the FTSE 30 share index during a period when government economic policy towards the financial markets was relatively unchanging. The EMH would suggest random walk behaviour but this does not occur; instead the data series has significant heteroscedasticity. The series is successfully explained by a GARCH M(1, 1) model. We use the BDS test to show that the residuals from this model are IID.
