Abstract

This study aims to address the issue of portfolio theory, which has been a topic of debate in financial. The main objective of this study is to investigate if the portfolio theory is useful in practical application. This study determines the feasibility of applying portfolio theory in real life through comparison and case studies. The findings of the study indicate that its assumptions about investor behavior often conflict with reality. The study provides insights into financial, which may contribute to future research and practice.
