| dc.description.abstract | Volatilitas pasar modal menuntut pendekatan matematis dalam pengambilan keputusan investasi. Penelitian ini menganalisis pembentukan portofolio saham syariah optimal menggunakan model Markowitz pada indeks IDX-MES BUMN 17 periode 2025 berdasarkan harga penutupan mingguan yang dioptimasi secara kuadratik dengan matriks varians-kovarians. Dari 17 emiten populasi, empat saham dieksklusi karena mencatatkan expected return negatif. Hasil komputasi menunjukkan global minimum variance portfolio menekan risiko hingga 12,70% dengan expected return 37,96%, didominasi saham JRPT (52,27%). Kinerja paling efisien dicapai oleh tangency portfolio dengan expected return 58,00%, risiko 15,64%, dan Sharpe ratio 3,371, yang dibentuk oleh JRPT (40,00%), IPCC (26,73%), ANTM (20,74%), TLKM (8,44%), dan PGAS (4,09%). Portofolio Markowitz ini terbukti 2,9 kali lebih efisien dibandingkan diversifikasi naif (1/N). Temuan ini mengarahkan pengelola dana untuk mengadopsi penapisan risiko kuantitatif guna merealisasikan prinsip tawazun (keseimbangan) dan hifdzul mal (perlindungan harta) dalam investasi syariah. | |
| dc.description.abstract | Capital market volatility requires mathematical approaches in investment decision-making. This study analyzed the formation of an optimal Islamic stock portfolio using the Markowitz model on the IDX-MES BUMN 17 Index for the 2025 period, based on weekly closing prices optimized through a variance-covariance matrix. This study excluded four of the 17 population issuers due to negative expected returns. The global minimum variance portfolio (MVP) minimized risk to 12.70% with a 37.96% expected return, dominated by JRPT stock (52.27%). The most efficient performance was achieved by the tangency portfolio, with a 58.00% expected return, 15.64% risk, and a Sharpe ratio of 3.371, composed of JRPT (40.00%), IPCC (26.73%), ANTM (20.74%), TLKM (8.44%), and PGAS (4.09%). This Markowitz portfolio proved 2.9 times more efficient than naive (1/N) diversification. These findings direct fund managers to adopt quantitative risk screening to realize the principles of tawazun (balance) and hifdzul mal (wealth protection) in Islamic investment. | |
