Abstract

With the further improvement of the financial system and the arrival of the era of big data, the application of new technologies in the financial field is deepening. Based on Markowitz portfolio theory, this paper using “Mean – Variance Model” select three funds and T-bills as risk-free rate in the market for portfolio investment analysis. Through empirical analysis, we obtain the optimal portfolio with the largest Sharpe ratio and the optimal portfolio with the smallest variance and conduct comparative analysis on their expected return rate, standard deviation and Sharpe ratio. The obtained results further explain that Markowitz theory plays an important role in selecting optimal portfolio in financial risk management. At the same time, this paper lays a foundation for the practice and development of R software in the field of financial analysis.
