Based on Markowitz's portfolio theory, the risks and returns of stocks can be obtained from calculating the historical data, ensuring effective returns with low risk by decentralized investment, which has a considerable degree of practical significance to China's public investment under the current situation. In recent years, the total market capitalization of the new energy industry and the attainable gains from it are growing rapidly, in which case investors need to analyze and evaluate the volatility to determine how to invest. This paper extracts the historical closing price of new energy automobile related industry 7 stocks from June 2018 to March 2024 through the SuperMind database and establishes the mean-variance model, showing the optimal portfolio of new energy industry in the market with short-selling and the market without short-selling and giving a practical investment proposal on weights allocation.
