Abstract

This study aims to examine the differences in stock prices before and after the Palestine-Israel ceasefire event in fast-food restaurant companies,  Pizza Hut and KFC. International-scale events may influence investor perceptions, as reflected in stock price movements in the capital market. This study employs a comparative quantitative approach using stock price data collected over 30 days before and 30 days after the ceasefire event. The analyzed data consist of secondary data processed through descriptive statistics, normality tests, and hypothesis testing. The findings indicate that the average stock price of PZZA increased after the event, whereas FAST experienced a decline in its average stock price. These results reveal differences in stock prices between the periods before and after the ceasefire event in both companies. The findings further suggest that geopolitical events are associated with changes in stock prices in the fast-food restaurant industry, although market responses differ across companies. Therefore, future studies are recommended to expand the scope of research objects and extend the observation period to obtain a more comprehensive understanding of market responses to international events.

Abstract

This study examines the influence of macroeconomic variables on banking stock returns in Indonesia, with a comparative focus on state-owned and private banks. The macroeconomic variables analyzed include inflation, the BI Rate, and the rupiah exchange rate against the US dollar. This research applies a quantitative explanatory approach using monthly panel data from 2015 to 2025. The sample consists of six banking companies listed on the Indonesia Stock Exchange, namely three state-owned banks and three private banks, with a total of 792 observations. The data were analyzed using panel data regression through the Common Effect Model estimated by Ordinary Least Squares. The findings indicate that inflation, interest rates, exchange rates, and bank ownership simultaneously have a significant effect on banking stock returns. Partially, the BI Rate and exchange rate have a negative and significant effect on stock returns, while inflation has no significant effect. The ownership dummy shows no significant difference between the stock returns of state-owned and private banks. These results suggest that macroeconomic conditions, particularly interest rates and exchange rate movements, play a more dominant role in influencing banking stock returns than bank ownership characteristics. The study contributes to investment decision-making by highlighting the importance of monitoring monetary policy and exchange rate stability in assessing banking sector stock performance.

Abstract

This study aims to analyze the effect of Dividend Payout Ratio (DPR) and Firm Size on Company Value (PBV) with Profitability (ROE) as a mediating variable in energy sector companies on the Indonesia Stock Exchange for the 2018–2024 period. The method used is Partial Least Squares–Structural Equation Modeling (PLS-SEM). The results showed that DPR and Firm Size did not have a significant effect on ROE or PBV, and ROE also did not have a significant effect on PBV. Thus, ROE does not mediate the relationship between these variables. The insignificance of this influence reflects the characteristics of the energy sector which is volatile, capital-intensive, and facing a new and renewable energy transition. Investors pay more attention to asset efficiency, sustainable profitability, and capital structure than dividend policies or company scale.
