Abstract

Up to now, the effects of diversification of business portfolio has been a controversial topic. Models of the effects of diversification on performance are categorized in three groups: Value Enhancing Models, Inverted-U Models and Value-Destroying Models. Researches on this subject have not achieved maturity because They have not achieved consensus on a single conclusion and These researches have not achieved interpretable and stable results. Specially diversification of Iranian holding companies have not been considered yet. In this survey, we consider the impact of business portfolio diversification on financial performance and risk. 37 LLP conglomerates that are active in The Teheran Stock Market are considered during 1390 to 1394 (5 years). For considering validity of model and coefficients respectively the F test and T test is used. These tests are done by Eviews 9. In the 95% level of confidence, the conclusions shows that there isn’t a linear relationship between diversification with ROE and risk.
