Judul: Analisis Faktor Internal dan Eksternal yang Memengaruhi Return Investasi Reksadana Syariah Pendapatan Tetap di Indonesia
Abstrak: Indonesia sebagai negara mayoritas muslim memiliki instrumen keuangan syariah yang dijalankan berdasarkan prinsip islam, salah satunya adalah reksadana syariah. Reksadana syariah merupakan alternatif dalam investasi syariah yang memberikan kemudahan bagi investor yang memiliki kekurangan dana, waktu dan pengetahuan dalam pengelolaan dana investasi. Pertumbuhan reksadana syariah yang terus berkembang setiap tahunnya ternyata belum mampu bersaing dengan reksadana konvensional. Hal ini dapat dilihat dari Nilai Aktiva Bersih (NAB) yang lebih kecil dibandingkan dengan reksadana konvensional sehingga berdampak pada return investasi yang didapatkan investor. Penelitian ini bertujuan untuk menganalisis faktor internal dan eksternal yang memengaruhi return investasi reksadana syariah pendapatan tetap. Return diukur dengan perhitungan NAB tahun berlaku dibandingkan dengan NAB tahun sebelumnya. Metode yang digunakan adalah metode regresi data panel dengan periode observasi dari tahun 2018 sampai 2020 dan sampel yang digunakan berjumlah delapan produk reksadana syariah pendapatan tetap. Hasil penelitian menunjukkan bahwa variabel ukuran produk yang dilihat dari volume perdagangan berpengaruh positif dan signifikan terhadap return investasi reksadana syariah pendapatan tetap, sedangkan variabel IHSG, Inflasi, kurs, JUB, exchange rate dan portfolio turnover tidak berpengaruh signifikan terhadap return., Indonesia as a Muslim-majority country has Islamic financial instruments that are run based on Islamic principles, one of which is Islamic mutual funds. Islamic mutual funds are an alternative in Islamic investment that provides convenience for investors who have a shortage of funds, time and knowledge in managing investment funds. The growth of Islamic mutual funds which continues to grow every year has not been able to compete with conventional mutual funds. This can be seen from the Net Asset Value (NAV) which is smaller than conventional mutual funds so that it has an impact on investment returns that investors get. This study aims to analyze the internal and external factors that affect investment returns on fixed income Islamic mutual funds. Return is measured by calculating the current year's NAV compared to the previous year's NAV. The method used is the panel data regression method with an observation period from 2018 to 2020 and the sample used is eight fixed income sharia mutual fund products. The results showed that the product size variable as seen from trading volume had a positive and significant effect on investment returns on fixed income sharia mutual funds, while the IHSG, inflation, exchange rate, JUB, exchange rate and portfolio turnover variables had no significant effect on return.
