Abstract

The purpose of our study is to investigate the application of Modern portfolio Theory in the stock markets and design an investment strategy for risk-averse investors. The principle of the Modern portfolio theory is mean-variance analysis, that is we use mean and variance to measure the expected return and risk of portfolios respectively, and select an optimal portfolio based on it. The core idea is diversification of investments, which means to divide the investment into a combination of different financial assets or shares of different companies, such as stocks and securities. We investigate the adjusted closing stock price of five companies: Facebook, Amazon, Apple, Netflix and Google, from 2011 to 2021. Our results show that the minimum risk (annualized volatility at 23%) can be obtained when the expected annualized return is at level of 28%. A higher expected annualized return (at the level of 33%) might be achieved if the investors are willing to take more risk (annualized volatility at 25%).
