  本文選題:內(nèi)幕交易 + 超額收益; 參考:《上海交通大學(xué)》2014年碩士論文


【摘要】:本文首先研究了內(nèi)幕交易的監(jiān)管有效性,以A股市場(chǎng)發(fā)生重大事項(xiàng)并且未被證監(jiān)會(huì)處罰的上市公司為樣本,對(duì)事件中的超額收益進(jìn)行分析。研究發(fā)現(xiàn),,相比于因內(nèi)幕交易被證監(jiān)會(huì)處罰的企業(yè),未被處罰的企業(yè)在首次公告日前的超額收益波動(dòng)率明顯偏低。研究發(fā)現(xiàn)在2012年《司法解釋》出臺(tái)后,內(nèi)幕交易的監(jiān)管有效性大幅提升,對(duì)重大內(nèi)幕交易行為起到了一定的震懾作用。其次,本文研究了內(nèi)幕交易的影響因素,本文認(rèn)為上市公司治理結(jié)構(gòu)的缺陷、信息透明度較低、投資者之間的信息不對(duì)稱以及法律制度環(huán)境不佳是影響內(nèi)幕交易行為的主要因素。在第二部分,本文研究了內(nèi)幕交易的市場(chǎng)反應(yīng)。通過對(duì)1996年至2013年期間內(nèi)被證監(jiān)會(huì)處罰及被法院判決的內(nèi)幕交易公司的事后期市場(chǎng)表現(xiàn)進(jìn)行分析。研究發(fā)現(xiàn),進(jìn)行了內(nèi)幕交易的上市公司相對(duì)于未進(jìn)行內(nèi)幕交易的上市公司,事后的股票超額收益并未明顯偏低。。內(nèi)幕交易并未給上市公司帶來很嚴(yán)重的市場(chǎng)和經(jīng)濟(jì)后果。
[Abstract]:This paper first studies the effectiveness of the regulation of insider trading, taking the listed companies which have not been punished by the CSRC as the sample to analyze the excess returns in the A share market. The study found that the volatility of excess returns of unpunished enterprises was significantly lower than that of those punished by the CSRC for insider trading before the first announcement day. It is found that after the introduction of Judicial explanation in 2012, the effectiveness of insider trading has been greatly improved, which has a certain deterrent effect on the major insider trading behavior. Secondly, this paper studies the influencing factors of insider trading. Asymmetric information among investors and poor legal system are the main factors affecting insider trading. In the second part, this paper studies the market reaction of insider trading. This paper analyzes the late market performance of insider trading companies that were penalized by the CSRC and adjudicated by the court during the period from 1996 to 2013. The study found that the stock excess return of the listed company with insider trading was not significantly lower than that of the listed company without insider trading. Insider trading does not have serious market and economic consequences for listed companies.
