Abstract

This research focuses on the impact of credit and market risk, capital, and liquidity factors on the efficiency of Islamic banks operating under Government-Linked Companies (GLCs) in Malaysia. Based on Bank Islam Berhad, CIMB Islamic Berhad, and Maybank Islamic Berhad, the study examines how these variables influence profitability, measured by Return on Assets (ROA). Upon dealing with the quantitative approach, the findings contrast the literature in that risk constituents while varied in their significance have an equal significance on overall profitability. This study contributes to the literature on Islamic finance by providing practical recommendations for enhancing risk management and ensuring financial sustainability in the Islamic banking sector.

Abstract

This study evaluates the benefits of portfolio diversification by examining the relationship between the returns of Sido Muncul Tbk (SIDO) and Indofood CBP Sukses Makmur Tbk (ICBP) using Modern Portfolio Theory (MPT). Daily closing prices from October 1, 2023, to September 30, 2024, were analyzed. Daily returns were calculated and assessed using descriptive statistics, Pearson correlation, and mean–variance optimization to construct the efficient frontier and identify the optimal allocation. The results show ICBP offers a lower return (6.25%) and lower risk (1.92), while SIDO provides a higher return (7.35%) with slightly higher risk (1.97). Portfolio optimization suggests a 50/50 allocation yields the most balanced outcome, minimizing risk (1.46) while maintaining a solid return (6.80%). The low correlation (0.13) between the two stocks highlights significant diversification benefits. Practical implications include providing Shariah-compliant investors with empirical guidance to build efficient portfolios that balance return and risk. The study is limited by its use of only two stocks and a one-year observation period, which may affect the generalizability of results to broader market conditions.

Abstract

This study aims to analyze the feasibility assessment of gold pawn financing products and the implementation of Sharia-based Good Corporate Governance (GCG) at Bank Syariah Indonesia, KCP Surabaya Manukan. A descriptive qualitative approach was employed, with data collected through observation, interviews, and documentation. Data analysis involved reduction, presentation, and conclusion drawing. The findings reveal that the bank applies three feasibility indicators: character, capacity, and collateral (assessed through physical testing, chemical testing, and specific gravity testing), while capital and condition of economy are not applied. The implementation of Sharia-based GCG covers transparency, accountability in accordance with relevant laws and DSN-MUI fatwas, and fairness in customer service. However, accountability and professionalism aspects remain suboptimal due to the lack of specialized gold pawn training for staff, despite formal appointment. This condition may pose operational risks to the bank.
