Representativeness Bias, Perilaku Herding-Effect, Teori Heuristic.Abstract
Penelitian ini bertujuan untuk menganalisa pengaruh representativeness bias dan herding behavior terhadap pengambilan keputusan investasi yang rasional yang dideteksi dengan menggunakan perspektif Teori Heuristik pada komunitas Investor Saham Pemula (ISP) di Jawa Timur. Penelitian ini menggunakan metode campuran dilengkapi dengan strategi penjelas berurutan. Studi penelitian ini menggunakan data primer yang diperoleh dengan menyebarkan kuesioner online di 10 kota di Jawa Timur dan wawancara dengan praktisi ahli. Sampel penelitian ini adalah 111 investor aktif yang berdagang secara mandiri. Dalam kaitannya, analisis data dilakukan melalui regresi linier ganda. Penelitian ini berhasil membuktikan bahwa perilaku representativeness bias berpengaruh negatif terhadap pengambilan keputusan atas investasi rasional. Di sisi lain, tidak ada bukti yang menunjukkan pengaruh herding behavior mempengaruhi pengambilan keputusan investasi. Fenomena tersebut mengindikasikan bahwa investor lebih mengandalkan informasi yang diperoleh melalui hasil nalar pribadi dibandingkan mengikuti keputusan investor lain.
