Abstract

Abstract : This study investigates the impact of oil and gold price volatility on stock market returns in Indonesia during periods of geopolitical instability, specifically the Russia-Ukraine conflict and the Israel-Hamas crisis. Utilizing secondary data, the research analyzes the daily closing prices of West Texas Intermediate (WTI) crude oil, Brent Crude Oil, gold, and the Jakarta Composite Index (JCI). The Generalized Autoregressive Conditional Heteroskedasticity (GARCH) (1,1) model is employed as the primary analytical framework. The findings reveal that oil and gold price volatility exerts a positive and unidirectional influence on Indonesian stock returns during the aforementioned geopolitical crises. This suggests that investors tend to seek safe-haven assets, such as gold, in times of economic uncertainty and geopolitical turmoil. The increased volatility in gold prices is indicative of heightened market instability, particularly during financial crises and geopolitical disruptions. These results corroborate the notion of gold serving as a reliable safe-haven asset during periods of economic and geopolitical uncertainty.Abstrak : Penelitian ini menyelidiki dampak volatilitas harga minyak dan emas terhadap imbal hasil pasar saham di Indonesia selama periode ketidakstabilan geopolitik, khususnya konflik Rusia-Ukraina dan krisis Israel-Hamas. Dengan memanfaatkan data sekunder, penelitian ini menganalisis harga penutupan harian minyak mentah West Texas Intermediate (WTI), Brent Crude Oil, emas, dan Indeks Harga Saham Gabungan (IHSG). Model Generalized Autoregressive Conditional Heteroskedasticity (GARCH) (1,1) digunakan sebagai kerangka analisis utama. Temuan penelitian ini mengungkapkan bahwa volatilitas harga minyak dan emas memberikan pengaruh positif dan searah terhadap imbal hasil saham Indonesia selama krisis geopolitik tersebut. Hal ini menunjukkan bahwa investor cenderung mencari aset safe haven, seperti emas, di saat ketidakpastian ekonomi dan gejolak geopolitik. Meningkatnya volatilitas harga emas merupakan indikasi meningkatnya ketidakstabilan pasar, terutama selama krisis keuangan dan gangguan geopolitik. Hasil ini menguatkan gagasan bahwa emas berfungsi sebagai aset safe haven yang andal selama periode ketidakpastian ekonomi dan geopolitik.

Abstract

The aim of this study is to examine the effect of company performance and corporate governance on the disclosure of carbon emissions of manufacturing companies. This study uses secondary data in the form of financial reports and sustainability reports from manufacturing companies that have been listed on the Indonesia Stock Exchange (IDX) for the period 2015 -2022. The data collection technique used a purposive sampling method with a sample of 93 companies. Data analyzed by using panel regression method. The results of this study show that company performance variables have a significant positive effect on disclosure of carbon emissions, but corporate governance variables do not have a significant negative effect on carbon emissions. The study suggests corporate governance will reduce the company's carbon emission levels. Hence, it is very important to enhance the company’s corporate governance practices beyond the mandatory matters. This study is one among few studies which have been conducted in Indonesia to examine company performance and corporate governance regarding carbon emissions in the manufacturing industry in Indonesia. This study focuses on examining the manufacturing industry in Indonesia and this research has different results and points of view from previous researches.

Abstract

This research was conducted to see if there was any herding behavior in stock trading in Indonesia, especially the LQ45 index constituents, which were affected by the effect of the removal of the broker code by the Indonesian Stock Exchange which began on December 6, 2021. The period used in this study was the period before the removal of the broker code, namely June 15, 2020 to December 5, 2021 and the period after the removal of the broker code, namely December 6, 2021 to June 30, 2023. The method used in this study is the approach method by Chang et al. (2000) namely CSAD (Cross Sectional Absolute Standard Deviation) to detect indications of herding behavior. The results of this study indicate that there was no herding behavior on the LQ45 trading stock index either before or after the removal of the broker code. This means that investors act rationally whether the broker code exists or not

Abstract

This study examines whether government and corporate bonds in Indonesia act as hedging or safe haven assets during the COVID-19 pandemic and the Russia–Ukraine war. This study using data started from March 3, 2020 which is the date of the first Covid-19 case emerged in Indonesia to March 29, 2024 even though the war is not over yet on the time this study being conducted. The cut-off date for the Russia-Ukraine war is February 24, 2022. Generalized Autoregressive Conditional Heteroskedasticity (GARCH) is used in order to test the potential of bonds as hedges, while QREG used in order to test the potential of bond as safe haven. The findings show that during the period of financial and geopolitical crisis, Indonesian government and corporate bonds cannot be an effective safe haven or hedge against the stock market. While they can serve as diversification assets due to their stable volatility, these bonds lack the consistent negative correlation with the Composite Stock Price Index (CSPI) required for safe haven assets. Investors and portfolio managers should be cautious in relying on government bonds and corporate bonds as hedge against stock market declines. The results suggest that bonds may not provide the expected protection against stock market declines, so investors need to consider alternative diversification strategies or other hedging instruments when making investment decisions.

Abstract

This study aims to develop a dynamic portfolio model based on asset class, precious metals, world oil, and dollar index. This study performs a comparative test between the Dynamics Conditional Correlation (DCC) and Asymmetric Dynamics Conditional Correlation (ADCC) to determine the best method in forming a dynamic portfolio. Four big cap companies on the Indonesian stock market (BBCA, BBRI, BMRI, and ASII) are examined in this study. The data used were daily returns for the period of January 2, 1998 – December 31, 2020, analyzed using Dynamics Conditional Correlation (DCC) and Asymmetric Dynamics Conditional Correlation (ADCC). The results of empirical testing suggest that including gold, world oil, and dollar index into the dynamic portfolio might increase the portfolio performance and minimize its risks. The stock-gold portfolios formed by utilizing the DCC and ADCC-GARCH methods outperform those composed of only stock. Gold could act as a financial system stabilizer by mitigating losses in the case of extreme negative market shocks. Stock-WTI portfolios formed by utilizing the DCC and ADCC-GARCH methods also outperform those composed of only stock.

Abstract

This research aims to determine liquidity and volatility conditions and differences in herding behavior during the pre-pandemic, early pandemic, and the new normal period of the COVID-19 pandemic in Indonesia. This research examines the microstructure and proves herding behavior on the Indonesian Stock Exchange (IDX). This research will also look at liquidity and volatility to see market sentiment because investor behavior can be reflected in liquidity and volatility. The population used in this research is the IDX-80 index, with 48 companies as the sample. This study uses CSAD to test herding behavior because it is not sensitive to outliers. This research found that the highest market liquidity and volatility occurred during the early pandemic, and the highest herding behavior occurred during the new normal period. The market response to each event can also determine the direction of stock movements, so investors can take advantage of this period to collect shares and sell them again when prices rise. This research offers a summary of the Indonesian capital market during significant events, which can assist investors in developing investment plans that consider the course of events. Practically, this study offers actionable insights for investors by explaining how market conditions during different phases of the pandemic influence investment strategies.
