【摘要】:本文以中國(guó)創(chuàng)業(yè)板上市公司的高管減持事件為研究對(duì)象,采用事件研究法分析2010年11月1日至2013年12月31日創(chuàng)業(yè)板高管減持的市場(chǎng)反應(yīng),并從交易特征、高管特征、公司特征等角度分析其對(duì)市場(chǎng)反應(yīng)的影響。研究結(jié)果表明:創(chuàng)業(yè)板高管的減持行為有明顯的市場(chǎng)反應(yīng),在高管減持交易日前公司股票的累計(jì)超額收益處于上升趨勢(shì),在減持交易日達(dá)到最大值,而在減持后的第一個(gè)交易日立即轉(zhuǎn)為下降趨勢(shì),并于減持公告日達(dá)到最低值,呈現(xiàn)出明顯的倒V形變化趨勢(shì)。通過(guò)進(jìn)一步地分組研究發(fā)現(xiàn),減持規(guī)模越大,對(duì)市場(chǎng)的負(fù)面沖擊越強(qiáng)烈;高管職位的不同對(duì)于減持交易日的超額收益并沒(méi)有顯著影響,但與減持后的累計(jì)超額收益呈正相關(guān);業(yè)績(jī)表現(xiàn)越好、成長(zhǎng)性水平越高的公司,其高管減持的負(fù)向反應(yīng)越小。另外,本文通過(guò)對(duì)比創(chuàng)業(yè)板與中小板上市公司高管減持的市場(chǎng)反應(yīng),發(fā)現(xiàn)二者并無(wú)顯著差異,高管減持前后的市場(chǎng)波動(dòng)幾近一致。 與主板市場(chǎng)不同,創(chuàng)業(yè)板市場(chǎng)存在更大的不確定性,,創(chuàng)業(yè)板高管的大量減持對(duì)公司未來(lái)的發(fā)展具有顯著的預(yù)警作用。本文的研究結(jié)論,期望能為投資者決策提供參考,為監(jiān)管機(jī)構(gòu)對(duì)當(dāng)前中國(guó)創(chuàng)業(yè)板市場(chǎng)高管減持的監(jiān)管提供經(jīng)驗(yàn)證據(jù)。
[Abstract]:This paper analyzes the market reaction of gem executives reduction from November 1st 2010 to December 31st 2013 by using the event study method with the listed companies of China growth Enterprise Market as the research object. And from the transaction characteristics, executive characteristics, corporate characteristics and other aspects of the analysis of its impact on the market response. The results show that: the gem executive reduction behavior has a clear market response. The cumulative excess returns of the company's stocks were on the rise before the trading day of senior management reduction, reached the maximum value in the trading day of reduction, and turned to the downward trend immediately after the first trading day after the reduction. And reached the lowest value on the day of the announcement of reduction, showing an obvious trend of inverted V-shape change. Through further grouping research, the larger the scale of the reduction, the stronger the negative impact on the market. The difference of executive position has no significant influence on the excess return of the trading day, but it has positive correlation with the accumulated excess return after the reduction. The better the performance, the higher the growth level, the smaller the negative response to the reduction. In addition, this paper compares the market reaction between gem and small and medium-sized listed companies. It is found that there is no significant difference between the two, and the market volatility is almost the same before and after senior management reduction. Different from the main board market, there is greater uncertainty in the gem market, and the reduction of gem executives has a significant early warning effect on the future development of the company. It is expected to serve as a reference for investors to make decisions and provide empirical evidence for regulators to regulate the current reduction of senior executives in China's gem market.
