投资者情绪与创业板收益关系的实证研究

摘要2009年10月，深圳证券交易所创业板开板，为具有高成长性和高风险性的企业提供了重要融资途径，也为风险投资和私募投资提供了更为灵活的退出机制。然而创业板开板三年以来却饱受“三高”现象的困扰，专家学者对其进行的实证研究也大多局限于标准金融理论。本文受行为金融学的启发，从投资者情绪方面入手，使用主成分分析法构造出综合情绪指数，再通过VAR模型和格兰杰因果检验，揭示投资者情绪与我国创业板市场收益率之间的互动关系，并试图发掘导致创业板金融异象的重要原因，同时给出相应的政策建议。65952

Title : Empirical Study on Investor sentiment and Stock Return Of China GEM

Abstract

In 2009 October，the GEM(Growth Enterprise Market) of Mainland China was opened in Shenzhen Stock Exchange. It provides important financing channels for those enterprises with both high growth speed and high risk，as well as a more flexible exit mechanism for venture capital and private investment. However, not long before its third anniversary, the GEM has been confused by the phenomenon known as “three high” , namely: the high issue price, high price-earnings ratio, superb raise funds, and most of the studies on “three high” are restricted to the traditional finance theory. Inspired by the behavior finance theory, this paper starts with the investor sentiment, using principal component factor analysis to construct a composite index. Then we analyze the relationship between investor sentiment and stock market return rate through VAR model and Granger causality Tests. Based on the empirical study, we try to find the reasons of the anomalies and suggestions will be made to improve the China GEM.
