Abstract

Shares is one of investment with moderate to high level of risk profile and return rate, and is a legal ownership proof of a company (Ltd). To obtain an optimum return with possible low risk, price of shares can be predicted or analyzed via fundamental or technical analysis. One of the most popular technical analysis is by employing computer algorithms as a device to help making decision. Long short term memory (LSTM), as a deep improvement of recurrent neural networks (RNN), is a commonly used method to predict shares price. BUMI, as one of shares in the energy sector, is the most concerned shares due to the geopolitical conflict in Europe. This research aims to predict BUMI shares price using LSTM by considering three parameters, i.e. number of hidden layers, epoch, and learning rate. Linear regression is used to obtained optimum values of each parameter whichs further combined to yield the best performance of the algorithm. Based on the analysis, the combination of minimum and optimum parameters results in the best performance by RMSE value.

Abstract

This study examines the relationship between CEO nationality, capital structure, and firm activity on firm value, both directly and indirectly through financial performance. The sample consists of primary consumer goods companies listed on the Indonesia Stock Exchange during 2018–2024, resulting in 406 observations analyzed using Stata 17. The results show that CEO nationality, firm activity, and financial performance positively affect firm value, while capital structure has no direct effect. These findings suggest that the presence of foreign CEOs, effective firm activities, and strong financial performance enhance investors’ perceptions of firm value. Further results indicate that CEO nationality and firm activity do not affect financial performance, whereas capital structure negatively affects financial performance, implying that higher debt usage may increase financial burdens and reduce financial performance. Moreover, financial performance fully mediates the relationship between capital structure and firm value but does not mediate the influence of CEO nationality or firm activity on firm value. Overall, this study contributes to the literature by emphasizing the important role of financial performance in explaining firm value.
