Dalam penelitian ini, penulis membandingkan portofolio saham yang dibuat dengan metodologi Dow Jones dan Markowitz, yang mengandalkan rekomendasi saham dari Benjamin Graham. Tujuannya adalah untuk memeriksa apakah portofolio yang mengikuti metode ini dapat berkinerja lebih baik daripada indeks pasar saham utama Indonesia, IHSG (Indeks Harga Saham Gabungan) dan IDX30, dalam periode 2018 hingga 2023. Proses pemilihan saham menggunakan aturan Graham dengan menargetkan perusahaan yang rasio laba dibagi harga dua kali lipat dari imbal hasil obligasi berperingkat AAA (dalam penelitian ini menggunakan rate Bank Indonesia (BI) yang dirata-ratakan selama 5 tahun dari tahun 2018 hingga 2023) dan yang utangnya kurang dari nilai bukunya. Portofolio Dow Jones terdiri dari 30 saham berbobot sama yang dipilih dari emiten yang memenuhi syarat, dan portofolio Markowitz dibangun dengan mengikuti pendekatan mean-variance dan fungsi Lagrangian sehingga mendapatkan 14 saham. Penelitian ini melihat kedua portofolio menggunakan pengembalian mingguan, deviasi standar, dan Rasio Sharpe dan memeriksa apakah kinerjanya lebih baik daripada IHSG dan IDX30. Terlihat bahwa kedua portofolio tersebut berkinerja lebih baik daripada indeks dalam hal pengembalian yang disesuaikan dengan risiko, yaitu 0,32% per minggu untuk portfolio Dow Jones dan 0,42% per minggu untuk portfolio Markowitz jika dibandingkan dengan IHSG sebesar 0,07% per minggu dan IDX30 sebesar -0,01% per minggu.
