According to the corporate diversification, firms have a tendency to get more market share with diversifying in the local segment or in the international market. Theoretically, a contradictory exists between the profitable strategy and the value reducing strategy in the diversification strategy. In this paper, we measure firm’s efficiency by applying Data Envelopment Analysis (DEA) in manufacturing firms listed in Bursa Malaysia for five years. Meanwhile, a feed forward multilayer perceptron neural network is applied to model the mapping function between the input and output data to the efficiency score. Back propagation (BP) learning algorithm is applied to update network’s weights through minimizing the cost function, and the best topology of the network is conducted. The result of this study shows that there is a negative relationship between total product diversification and efficiency, and international diversification has a non-linear effect on the efficiency.

Changes in the equity value associated with the changes in the asset value and changes in asset risk can be characterized into potentially countervailing direct and indirect effects. The indirect effect of risk on equity value is a function of factors that affect the debt value of including leverage, asset value, and asset risk. This study examines whether the equity value reflects the profits and losses associated with the changes in the debt value consistent with the predictions of Merton [21]. The insurance companies listed in the Stock Exchange during 2010-2015 were selected to test the desired hypotheses. It has been found that the stock returns are negatively related to the increase in credit risk as reflected in the changes of estimated bond ratings. More importantly for the research question, it has been realized that the relationship between risk changes and equity returns is negative when the leverage is higher. Manuscript profile -
