Compare the Influence of the Shanghai Stock Index and Shenzhen Component Index on Stock Returns of Ningde Times

Abstract

Since the establishment of the Shanghai Stock Exchange and Shenzhen Stock, stock investment in China has gradually flourished in the past 20 years. When the figure of the stock market rises or falls, it has always affected the state of mind of every investor. For the Chinese stock market, the Shanghai Composite Index and the Shenzhen Component Index are equally important, which is helpful for us to understand the trend of the stock market in depth. However, most studies nowadays only focus on the influence of one index and ignore the essentials of the other, which could lead to a misjudgment by investors. because both indexes have a close correlation with the stock return. so it is necessary to compare the influence of the two indexes on stock returns at the same time. and base on this, I will compare the degree of correlation between the Shanghai index as well as the Shenzhen index on Ningde Times stock returns.
