The paper investigates the predictive content of semi-annually published\nearnings for the listed companies in the ASE over the period 1988-1997.\nBy observing correlation matrices between semi-annual and annual earnings we are\nconcerned to see if any regularities can be discovered. The degree of deviation between them\nis measured by calculating changes of semi-annual and yearly earnings. Different forecast errors\nmeasures such as the Mean Absolute Error, the Mean Square Error and the Average Error\nare used to provide evidence of the disparities of the forecast errors.\nThe results, indicate that interim reports as currently prepared cannot predict accurately\nthe annual earnings.
