Abstract

Investors have the opportunity to allocate their funds within the basic materials sector to achieve future profits, influenced by various macroeconomic factors such as the global index, macroeconomic conditions, world oil prices, China’s index, Arabia’s index, and competitiveness. This study seeks to analyze the impact of these factors during the leadership periods of Susilo Bambang Yudhoyono and Joko Widodo, categorized into high and low returns. Employing a descriptive and verification-based approach, the research utilizes secondary data and incorporates regression model selection, classical assumption testing, hypothesis testing, coefficient of determination, and differential effect testing through a dummy variable technique. The findings reveal that under both leaderships, the global index, macroeconomic conditions, world oil prices, China’s index, Arabia’s index, and competitive resources collectively influenced each return category. Additionally, differential effect testing results indicate that during Susilo Bambang Yudhoyono’s leadership, macroeconomic conditions, world oil prices, Arabia’s index, and competitiveness did not exhibit distinct effects within the high-return group with low returns. Conversely, under Joko Widodo’s leadership, the global index, macroeconomic conditions, world oil prices, China’s index, and competitiveness showed no distinct effects within the same group. In comparing high-return groups across both leaderships, the global index, world oil prices, China’s index, and competitiveness demonstrated no differential effects, while in the low-return group, only China’s index showed no variation.
