【摘要】:隨著經(jīng)濟(jì)的全球化發(fā)展,各國(guó)的金融市場(chǎng)也進(jìn)入全球化時(shí)代,實(shí)體經(jīng)濟(jì)與金融市場(chǎng)的相互作用也越來(lái)越明顯,金融市場(chǎng)的波動(dòng)對(duì)實(shí)體經(jīng)濟(jì)的影響非常大。無(wú)論是歷史上的荷蘭郁金香危機(jī),英國(guó)南海危機(jī)和1929年美國(guó)股市大崩盤,還是2008年由美國(guó)次貸危機(jī)引發(fā)的全球金融危機(jī)都對(duì)全球的實(shí)體經(jīng)濟(jì)產(chǎn)生了巨大影響。美國(guó)的次貸危機(jī)使得全球經(jīng)濟(jì)到現(xiàn)在都沒有完全恢復(fù),各國(guó)現(xiàn)在依然面臨著高失業(yè)率、低經(jīng)濟(jì)增長(zhǎng)、貨幣緊縮,有的國(guó)家還面臨著嚴(yán)重債務(wù)危機(jī)。金融市場(chǎng)的泡沫嚴(yán)重干擾了實(shí)體經(jīng)濟(jì)的正常運(yùn)行,也影響了金融市場(chǎng)的平穩(wěn)發(fā)展。因此,維持金融市場(chǎng)穩(wěn)定,減少金融市場(chǎng)泡沫,監(jiān)督投資者行為對(duì)我國(guó)經(jīng)濟(jì)的平穩(wěn)快速發(fā)展有著重要意義。 金融泡沫和市場(chǎng)上出現(xiàn)的許多其他異象使得以“有效市場(chǎng)假設(shè)”為主導(dǎo)的傳統(tǒng)金融理論受到了越來(lái)越多的質(zhì)疑和挑戰(zhàn)。傳統(tǒng)金融理論無(wú)法解釋這些異象,在錯(cuò)綜復(fù)雜的社會(huì)環(huán)境中,信息的傳遞會(huì)受到影響,同時(shí)投資者也很難一直保持理性人的狀態(tài),其做出的決策會(huì)受到很多因素的影響。行為金融理論把社會(huì)學(xué)和心理學(xué)與金融理論結(jié)合在一起受到了許多學(xué)者的追捧,也得到了迅速發(fā)展。噪聲交易作為行為金融理論的熱點(diǎn)之一,也是許多學(xué)者研究的重點(diǎn)。股票市場(chǎng)上是否存在噪聲交易,噪聲交易是否能夠長(zhǎng)期生存以及市場(chǎng)上噪聲交易的大小,對(duì)這些疑問(wèn)進(jìn)行研究,將對(duì)減少我國(guó)股票市場(chǎng)上噪聲交易的程度、化解噪聲交易風(fēng)險(xiǎn)、維持股票市場(chǎng)穩(wěn)定、保持市場(chǎng)效率有重要的理論意義和現(xiàn)實(shí)意義。 本文首先通過(guò)行為金融理論對(duì)市場(chǎng)異象的解釋,引出噪聲交易,充分解釋了噪聲交易產(chǎn)生的原因;其次通過(guò)DSSW模型證實(shí)了噪聲交易可以長(zhǎng)期存在于股票市場(chǎng)中,然后通過(guò)全面分析我國(guó)股票市場(chǎng)噪聲交易存在的情況和噪聲交易風(fēng)險(xiǎn)值;最后得出研究結(jié)論。各章的內(nèi)容如下: 第一章,引言。闡述本文的研究背景和選題意義,并指出本文的結(jié)構(gòu)安排、主要工作和不足之處。 第二章,文獻(xiàn)綜述。通過(guò)對(duì)國(guó)內(nèi)外相關(guān)文獻(xiàn)進(jìn)行回顧和梳理,將相關(guān)文獻(xiàn)按寫作的目的分成了三類,全面闡述了噪聲交易的研究成果和研究現(xiàn)狀,為本文寫作奠定了基礎(chǔ)。 第三章,噪聲交易成因及生存機(jī)制分析。本章從傳統(tǒng)金融理論的不足,引出行為金融理論,再?gòu)男袨榻鹑诶碚摰慕嵌?從理論上詳細(xì)地分析了噪聲交易產(chǎn)生的原因;然后通過(guò)DSSW模型證實(shí)噪聲交易者在與理性交易者進(jìn)行交易時(shí)能夠?yàn)樽约簞?chuàng)造生存空間,從而長(zhǎng)期存在于市場(chǎng)之中。這為本文研究奠定了理論基礎(chǔ)。 第四章,中國(guó)股市噪聲交易的描述性分析。本章主要將滬深兩市的市盈率、換手率和噪聲系數(shù)指標(biāo)與西方成熟金融市場(chǎng)的相應(yīng)指標(biāo)進(jìn)行對(duì)比,分析我國(guó)股票市場(chǎng)上噪聲交易的整體情況。 第五章,中國(guó)股票市場(chǎng)噪聲交易存在性的實(shí)證研究。本章依據(jù)隨機(jī)游走模型,檢驗(yàn)滬深兩市日收益率序列是否符合分布情況,從實(shí)證研究中國(guó)股票市場(chǎng)噪聲交易的存在狀況。 第六章,中國(guó)股票市場(chǎng)噪聲交易風(fēng)險(xiǎn)大小的實(shí)證分析。本章通過(guò)BAPM模型和CAPM模型計(jì)算出每只股票的噪聲交易風(fēng)險(xiǎn)值,從微觀角度考查噪聲交易風(fēng)險(xiǎn)的狀況。同時(shí),說(shuō)明BAPM模型比CAPM模型在計(jì)算資產(chǎn)風(fēng)險(xiǎn)溢價(jià)系數(shù)時(shí)更合理。 第七章,結(jié)論及政策建議。根據(jù)理論論證和實(shí)證結(jié)果分析得出本文的結(jié)論并提出相應(yīng)的政策建議。 本文的結(jié)論有:噪聲交易可以在股票市場(chǎng)中長(zhǎng)期生存;我國(guó)股票市場(chǎng)與西方成熟國(guó)家的股票市場(chǎng)相比,存在著比較嚴(yán)重的噪聲交易;牛市期間的噪聲交易比熊市期間的噪聲交易更為明顯;我國(guó)個(gè)股普遍存在著大小不一,不容忽視的噪聲交易風(fēng)險(xiǎn)。
[Abstract]:With the globalization of the economy, the financial markets of all countries have also entered the era of globalization. The interaction between the real economy and the financial market is becoming more and more obvious. The volatility of the financial market has a great impact on the real economy. Whether it is the historical Holland tulip crisis, the British South Sea crisis and the 1929 US stock market crash, or 2008 The global financial crisis caused by the American subprime crisis has greatly affected the global real economy. The subprime crisis in the United States has not fully recovered the global economy. Countries are still facing high unemployment, low economic growth, monetary tightening, and some countries facing a serious debt crisis. Financial market bubbles. The foam seriously interferes the normal operation of the real economy and affects the steady development of the financial market. Therefore, it is of great significance to maintain the stability of the financial market, reduce the bubble of the financial market, and supervise the behavior of investors for the smooth and rapid development of our country's economy.
The financial bubble and many other anomalies in the market have made the traditional financial theory dominated by the "effective market hypothesis" more and more questioned and challenged. The traditional financial theory can not explain these anomalies. In the complex social environment, the transmission of information will be affected, and it is difficult for investors to keep it at the same time. The decision of the rational person is influenced by many factors. The behavioral finance theory, which combines sociology and psychology with financial theory, has been pursued by many scholars and has developed rapidly. Noise trading is one of the hotspots of behavioral finance theory and also the focus of many scholars. Whether there is a noise transaction, whether the noise transaction can survive for a long time and the size of the noise trading on the market, the study of these questions will be of great theoretical and practical significance to reducing the degree of noise trading in the stock market, reducing the risk of noise trading, maintaining the stability of the stock market and maintaining the efficiency of the market.
This paper firstly explains the market anomalies through the behavioral finance theory, leads to the noise transaction, and fully explains the cause of the noise transaction. Secondly, it proves that the noise transaction can exist in the stock market for a long time through the DSSW model, and then through the comprehensive analysis of the situation of the noise trading and the value of the noise transaction risk in the stock market of our country. Finally, the conclusion is drawn. The contents of each chapter are as follows:
The first chapter, introduction, elaborates the research background and the significance of the topic, and points out the structure, main work and shortcomings of this article.
The second chapter, literature review. Through the review and combing of relevant literature at home and abroad, the relevant literature is divided into three categories according to the purpose of writing, and the research results and research status of noise trading are expounded comprehensively, which lays the foundation for the writing of this article.
In the third chapter, the causes of noise trading and the survival mechanism are analyzed. From the shortcomings of the traditional financial theory, this chapter leads to the behavioral finance theory, and then analyses the cause of the noise transaction in a detailed way from the perspective of behavioral finance theory, and then proves that the noise trader can be self - trading with the rational trader through the DSSW model. We have created the living space and thus exist in the market for a long time. This lays a theoretical foundation for this study.
The fourth chapter is a descriptive analysis of the noise trading in China's stock market. This chapter compares the price earnings ratio, turnover rate and noise factor of the Shanghai and Shenzhen two cities with the corresponding indexes of the western mature financial market, and analyzes the overall situation of the noise trading on the stock market in China.
The fifth chapter is an empirical study on the existence of noise trading in China's stock market. Based on the random walk model, this chapter tests whether the daily return sequence of the Shanghai and Shenzhen two cities conforms to the distribution, and studies the existence of the noise trading in the Chinese stock market.
The sixth chapter, the empirical analysis of the size of the noise trading risk in China's stock market. This chapter calculates the value of the noise transaction risk of each stock through the BAPM model and the CAPM model, and examines the situation of the noise transaction risk from the micro point of view. At the same time, it shows that the BAPM model is more reasonable than the CAPM model in calculating the asset risk premium coefficient.
The seventh chapter, conclusions and policy recommendations. Based on theoretical analysis and empirical results, the conclusions of this paper are obtained and corresponding policy recommendations are put forward.
The conclusion of this paper is that noise trading can survive in the stock market for a long time. Compared with the stock market in mature western countries, there is a relatively serious noise transaction in China's stock market; noise trading during the bull market is more obvious than that during the bear market; there are many different sizes in China's stock market, which can not be ignored. Noise trading risk.
