近些年来,股票市场愈加火热,许多投资者纷纷看好股市行情。股票市场迅速扩张,投资者在初期进入股票市场中时,最先关注股票名称这一最明显的信息,同时也出现了许多相似的股票名称,使得投资者更加容易混淆不同的股票。因此可以股票名称这一方面对于A股市场中股票价格间的“非理性联动”存在一定的影响。本文试图从股票名称对于这方面的“非理性联动”做出一定的分析与理解。本文的研究思路如下:首先,通过查阅一些资料文献,阅读之前的许多有关股票名称对于联动性影响的研究,本文将从三个方面对于股票联动性进行探究。本文通过实证分析发现:除了名称相似,没有其他相关性的配对股票价格变动之间存在很高的正相关性。
In recent years, the stock market has become increasingly hot, and many investors are optimistic about the stock market. Stock markets expanded rapidly. When investors first entered the stock market, they first focused on the most obvious information on stock names, and many similar stock names appeared, making it easier for investors to confuse different stocks. Therefore, the name of the stock can exert some influence on the “irrational linkage” between the stock prices in the A-share market. This article attempts to make a certain analysis and understanding of the “irrational linkage” of stock names in this respect. The research idea of this paper is as follows: Firstly, by referring to some information and literature and reading many previous studies on the influence of stock name on the linkage, this article will explore the stock linkage from three aspects. Empirical analysis shows that there is a high positive correlation between price changes of matched stocks with no other correlation except for similar names.
