我国股票市场行为及其影响因素分析 总被引:2,自引:1,他引:2
文章以2000年1月4日至2001年1月2日间在上海证券交易所A股市场交易的股票为样本,借鉴Debondt和Thaler(1985)的研究方法,发现我国股票市场存在明显的“反转趋势”,同时采用多元回归模型,分析影响反转趋势的主要因素,发现影响我国赢家组合和输家组合CAR反转的主要因素有形成期的CAR、换手率和公司资产规模。最后,作者从心理学和我国股票市场的制度背景探讨这种反转趋势的心理成因和制度成因。 相似文献

We investigate the role of international trade and proximity to war in international stock markets during the invasion of Ukraine by employing DiD designs and panel data comprising 70 stock markets. We find that differences in trade exposure to warring countries (trade effect) have a substantial and negative impact on non-European equity markets but are irrelevant for European markets. In contrast, differences in the distance to warring countries (proximity effect) have a significant and negative impact on European markets but have no bearing on non-European markets. We find that the relevance of rent from mineral, natural gas, and oil resources and the relevance of metals, ores, and fuels in exports operate as mitigators of the trade effect. Our paper provides valuable empirical evidence regarding the importance of mitigating the vulnerability of financial markets to international trade when a major war breaks out. 相似文献

2004年至今中国股票市场出现非理性的剧烈波动,原因之一就是政府调控股市的低效率。在建设市场经济过程中,政府适当的干预是维护股票市场正常发展的必要条件,而股市平准基金作为一种有效的政府宏观调控工具,将对我国股票市场的健康发展发挥作用。 相似文献

审计费用的决定因素一直是国外会计审计学界关注的热点问题之一。基于我国B股上市公司数据,以2001年~2003年我国B股的上市公司为样本,对境外审计师的审计收费展开研究可发现:2001年度审计费用的决定因素并不明显,且与事务所规模的关系不显性;在2002年和2003年,审计费用与总资产和事务所规模成显性相关。究其原因,主要是声誉机制、信息披露制度和我国审计市场竞争激烈等因素所致。 相似文献

This study presents analysis of the impact of “official product” sports sponsorships with the National Football League (NFL),
Major League Baseball (MLB), the National Hockey League (NHL), the National Basketball Association (NBA), and the Professional
Golfers Association (PGA) on the stock prices of sponsoring firms. The primary finding of the study is that, in the main,
announcements were accompanied by increases in shareholder wealth. The 53 sponsors analyzed experienced mean increases in
stock valuations of about $257 million. A multiple regression analysis of firm-specific stock price changes and selected corporate
and sponsorship attributes indicates that official product sponsorships with the NBA, NHL, and PGA and those with smaller
market shares were associated with the largest gains in share prices. Although corporate cashflow (a proxy for agency conflicts)
is statistically unrelated to shareholder approval, sponsorships by high-technology companies were associated with stronger
stock price reactions than otherwise. Finally, product congruence with the sponsored sport was positively related to changes
in stock prices.
