The Comparison of Technology Stocks between America and China in Portfolio Management

Abstract

The difference in technology stocks between different countries has been a topic that has been well thought out. This paper analyzes six representative stocks in the US and China, such as APPL, META, GOOG, and NTES, BIDU, and BABA in the US, and the paper analyzes them in depth by CAPM model and FF3F model. The paper calculated the expected return for the CAPM model and FF3F model and balanced the risk and expected return by the Sharpe ratio to find the technology stocks with the least risk and the most benefit. The results show that the CAPM model and FF3F model can balance the risk and expected return very well. Second, on balance, U.S. technology stocks generally perform better than Chinese technology stocks, with APPL and GOOD being two of the best performing U.S. technology stocks, as seen in both previous data and current expected return, beta and weights. These findings should be useful for investors interested in China and the US technology stocks.
