Additionally, this research aims to investigate the moderating effect of financial literacy on the relationship between these behavioral factors (overconfidence and herding) and investment decisions. This research is quantitative research. The sample of this research is Gen Y and Gen Z stock investors in Batam City, Indonesia.
