The result of this research indicates that diversification gives negative effect to ROA and Tobin’s Q, while for higher level of diversification, the effect on Tobin’s Q is relatively high. The negative effect of diversification on ROA is higher in the group of companies with higher ROA. The different results show that when using Tobin’s Q as a measure of companies’ performances, diversification gives negative impact to companies’ performance in the intermediate level.
