The Relationship between Ownership Structure and Accuracy of Future Earnings Forecast in Firms Listed in Tehran's Stock Exchange

This study aims to investigate and compare the ownership structure and the accuracy of future earnings forecast in firms listed in Tehran's Stock Exchange. This is a descriptive-applied study which has been analyzed by using cross-sectional data of 103 listed firms from 2009 to 2013. Multivariate regression has been used to examine the impact of each of the factors of ownership structure on earnings forecast accuracy. The results of testing the hypotheses show that three independent variables of ownership structure, institutional ownership, and ownership concentration have a significant relationship with earnings forecast accuracy, but individual ownership does not have a significant relationship with earnings forecast accuracy due to the short-term viewpoint of their shareholders. Also, among control variables, firm size has a significant effect on the dependent variable.
