This study aims to analyze and evaluate the impact of the implementation of PSAK No. 69 (Biological Assets) on market performance, with company performance acting as a mediating variable, in agricultural sector companies listed in Indonesia. PSAK No. 69 was adopted to improve transparency and reliability in the financial reporting of biological assets, which are a significant component in the agricultural industry. The research adopts a quantitative approach, utilizing secondary data derived from the annual financial reports of companies and stock price information accessed via the Indonesia Stock Exchange (IDX) and the official websites of relevant companies for the period of 2018–2023.The study investigates the relationship between the intensity of biological assets and company performance, as measured by Return on Equity (ROE), as well as the relationship between company performance and market performance, as measured by Stock Return. The analysis results indicate that the intensity of biological assets has a significant positive impact on ROE. However, the direct effect of biological asset intensity on Stock Return is not statistically significant. Nevertheless, the mediation test reveals that ROE has a significant positive effect on Stock Return, thereby confirming the mediating role of ROE in the relationship between biological asset intensity and Stock Return.These findings imply that the implementation of PSAK No. 69 indirectly affects market performance through its influence on company performance. This highlights the importance of financial performance as a transmission channel in understanding the market implications of accounting regulation changes. The study provides useful insights for investors, regulators, and other stakeholders in evaluating the financial and market consequences of biological asset accounting standards in the agricultural sector.

The purpose of this study is to determine partially or simultaneously with the variable profitability (which is proxied by ROE), investment decisions (which are proxied by PER), and funding decisions (which are proxied by DER) on firm value (which is proxied by PBV). The population in this study are mining companies in the oil and gas sub-sector which are listed on the Indonesia Stock Exchange for the 2017-2021 period either partially or simultaneously. The sampling technique uses saturated sampling method. From this method, all companies became the research sample during the five-year observation period. The total sample is 11 companies. The analytical method in this test uses multiple regression analysis using the SPSS version 25 test tool. The results show that partially profitability (which is proxied by ROE) has no effect on firm value (which is proxied by PBV, investment decisions (which are proxied by PER) has partially affected on firm value (which is proxied by PBV), and funding decisions (which are proxied by DER) partially have no effect on firm value (which is proxied by PBV), Profitability (which is proxied by ROE), investment decisions (which are proxied by PER), and funding decisions (which are proxied by DER) simultaneously affect firm value (which is proxied by PBV). The Fcount value is greater than the Ftable value (7.338>2.00758) with a significant value of 0.000 which means less than 0.05.

This study examines the relationship between corporate financial disclosure and investment decisions by shareholders and investors in capital markets. Using a comprehensive dataset of 486 publicly listed companies from multiple stock exchanges over a five-year period (2018-2022), we investigate how the quality, scope, and timing of financial disclosures influence investment behaviors, pricing efficiency, and capital allocation. Through multiple regression analysis, structural equation modeling, and panel data techniques, we find that higher disclosure quality is significantly associated with increased trading volumes (β=0.42, p<0.01), lower bid-ask spreads (β=-0.38, p<0.01), and reduced stock price volatility (β=-0.31, p<0.01). Our analysis reveals that voluntary disclosures beyond regulatory requirements have a stronger impact on institutional investor decisions compared to retail investors. Additionally, the study documents that forward-looking financial information and segment reporting have particularly strong effects on investment decisions during periods of market uncertainty. The findings contribute to disclosure theory and provide empirical evidence for regulators considering disclosure policy reforms, corporate executives formulating communication strategies, and investors developing investment frameworks that incorporate disclosure quality assessment. The study addresses the causality challenge through instrumental variable estimation and difference-in-differences analysis of regulatory changes, enhancing the robustness of the identified relationships.

This study examines the presence of the Monday effect in companies listed in the IDX30 index on the Indonesia Stock Exchange (IDX) from February 2018 to January 2023. The Monday effect is a market anomaly where stock returns on Mondays tend to be systematically different from other trading days. This phenomenon, if proven, challenges the efficient market hypothesis. The main research problem is whether the Monday effect exists in IDX30 stocks during the specified period. The study aims to provide empirical evidence regarding this anomaly in the Indonesian stock market. The research employs a quantitative approach, utilizing secondary data in the form of daily stock closing prices. The sample consists of 15 companies that were consistently listed in the IDX30 index throughout the study period, selected through a purposive sampling method. The analysis is conducted using the One-Way ANOVA test with SPSS 27 statistical software to compare stock returns across different trading days. The findings confirm the presence of the Monday effect in IDX30-listed stocks, indicating that stock returns on Mondays exhibit statistically significant differences compared to other days. These results suggest that behavioral factors and market inefficiencies may influence stock price movements in the IDX30 index. This study contributes to the literature on stock market anomalies and provides insights for investors and policymakers regarding trading strategies and market efficiency in Indonesia.

Determining the price of option contracts is a crucial aspect of financial markets, particularly for investors aiming to manage risk and make informed investment decisions. In this study, the price of an Asian call option is calculated using the Monte Carlo Stratified Sampling method based on the stock price data of Tesla, Inc. (TSLA) from January 2021 to December 2023. This method has been proven to reduce variance compared to the Standard Monte Carlo simulation, leading to faster price convergence and more efficient results. The parameters used in the simulation include the initial stock price  (S_0), number of simulations (N), maturity time  (T)dividend = 0, risk-free rate (r), strike price ( K), and volatility

Indonesia, which previously traded carbon through a voluntary market mechanism, has switched its carbon trading implementation through a carbon exchange (IDX Carbon) since September 26, 2023. This means that carbon trading in Indonesia is carried out through the Indonesia Stock Exchange (IDX), and all carbon units are traded as securities or securities, whereas previously carbon transactions in Indonesia were voluntary. The implementation of carbon trading is a form of Indonesia's commitment to implementing the Paris Agreement and the Kyoto Protocol in reducing Greenhouse Gas emissions by 29% in 2030 with its own capabilities and up to 41% with international support. In the implementation of carbon trading in Indonesia, it is carried out through a mandatory market and the Indonesia Stock Exchange has been appointed as the institution organizing carbon trading, but the regulations that form the basis for the implementation of carbon trading do not clearly regulate how to determine carbon prices, the institution authorized to issue Technical Approval for Upper Emission Limits for Business Actors (PTBAE-PU) and Greenhouse Gas Emission Reduction Certificates as units traded on the Carbon Exchange.

This literature review examines the impact of Corporate Social Responsibility (CSR) disclosure on mergers and acquisitions (M&A), focusing on market reactions, post-merger integration, and long-term performance. The review reveals that CSR disclosure often leads to positive market reactions, fostering investor confidence and increasing stock prices during M&A announcements. Furthermore, CSR practices contribute to smoother post-merger integration by aligning organizational cultures and fostering trust. Over the long term, companies that integrate CSR into their strategies generally experience enhanced brand value, customer loyalty, and competitive advantage. However, the effectiveness of CSR disclosure depends on its authenticity and strategic alignment with corporate goals. The review also highlights the need for further research in emerging markets and the exploration of qualitative approaches to deepen understanding of CSR’s role in M&A.

Political events often affect investors' decisions in taking wise steps. This paper analyses the impact of the political event "Emergency Alert" on the abnormal returns of IDX-listed infrastructure stocks using an event study methodology. Using a sample of 55 infrastructure stocks,the secondary data used are stock prices observed during the observation period. The difference in average returns before and after the event was assessed by analysing the estimated average abnormal return (AAR) and comparing the sample t-test statistics. The results of the analysis showed that a one-sample t-test (p < 0.05) indicated that abnormal returns were significant both before and after the event. However, a paired sample t-test showed that the difference between the average abnormal return rates of the two periods was not statistically significant (p > 0.05). This result suggests that although the "extraordinary alert" event has a significant impact on each period, its impact is not strong enough to cause a significant difference between periods. This study provides insights into stock market reactions to political uncertainty and serves as a reference for investors to address similar effects in the future.
