Abstract

Investasi merupakan upaya investor dalam mengorbankan konsumsi pada masa kini demi mendapatkan tingkat konsumsi lebih baik di masa depan. Untuk dapat memilih instrument investasi yang bagus yang dapat memenuhi ekspektasi para investor, diperlukanlah sebuah model seleksi saham terbaik. Saham-saham terbaik yang diseleksi menggunakan model indeks tunggal dan dikumpulkan dalam suatu wadah disebut dengan istilah portofolio optimal. Jakarta Islamic Index (JII) menjadi objek penelitian pada periode Januari 2020 hingga November 2023. Penelitian ini bertujuan untuk: Pertama, memberi gambaran dan saran mengenai pembentukan portofolio optimal berbasis model indeks tunggal setelah pandemi covid 19 pada indeks saham syariah di Indonesia khususnya JII. Kedua, mengetahui besaran bobot dana investasi pada masing-masing saham. Ketiga, mengetahui besaran return harapan dan risiko dari portofolio optimal saham. Hasil penelitian menunjukkan bahwa saham dengan kode ANTM dan TPIA merupakan saham terbaik dan layak masuk portofolio optimal. Besaran proporsi dana yang perlu dialokasikan dalam investasi adalah 93% pada ANTM dan 7% pada TPIA. Dengan proporsi dana tersebut investor akan mendapatkan return sebesar 2,77% dan risiko sebesar 2,71% yang mana return dan risiko ini lebih baik dari return dan risiko indeks saham gabungan.

Abstract

Introduction: This study explores a relatively under-researched area in Indonesia, namely the influence of women board members on bank performance and risk. This study fills a crucial gap in the literature on the influence of board characteristics on bank risk-taking and performance in Indonesia, a country in Asia with characteristics distinct from those of European countries. We investigate the impact of board characteristics on bank risk and performance. Methods: We used unbalanced panel data comprising 594 bank-year observations from Bank Indonesia for 2003-2022 and tested the model using a fixed-effects model, controlling for bank and year effects  Results: This study found that women board members have a positive effect on bank performance and a negative impact on bank risk. On the other hand, we find robust results related to women directors have a positive impact on bank performance and a negative impact on bank risk, even though examined with different models and proxies. On the other hand, Board size positively affects bank stability but shows no consistent impact on credit risk or performance during crises. In contrast, board independence is negatively associated with stability and weakens bank performance during crisis periods. Conclusion and suggestion: This research can contribute to the government’s attention to the importance of gender diversity on boards of directors. These study results can also guide other developing countries with similar legal systems.
