【摘要】:羊群效應(yīng)是指人們經(jīng)常受到多數(shù)人影響,,而跟從大眾的思想或行為,也被稱為“從眾效應(yīng)”。人們會(huì)追隨大眾所同意的,自己并不會(huì)思考事件的意義。該效應(yīng)最早應(yīng)用于證券市場(chǎng),最早是股票投資中的一個(gè)術(shù)語,主要是指投資者在交易過程中存在學(xué)習(xí)與模仿現(xiàn)象,“有樣學(xué)樣”,盲目效仿別人,從而導(dǎo)致他們?cè)谀扯螘r(shí)期內(nèi)買賣相同的股票。 羊群效應(yīng)作為行為金融學(xué)研究的一個(gè)重點(diǎn)領(lǐng)域,結(jié)合大量心理學(xué)(Psychologics)和行為學(xué)(Human Ethologics)等學(xué)科的前沿理論成果,修正并調(diào)整對(duì)于“理性人”假設(shè),成功解釋了市場(chǎng)間投資趨同性的市場(chǎng)異象并衍生出特定的實(shí)證模型。 本文結(jié)合行為金融學(xué)中對(duì)于羊群效應(yīng)的相關(guān)理論知識(shí)與分析模型。重點(diǎn)討論羊群效應(yīng)理論并運(yùn)用LSV模型對(duì)我國A股市場(chǎng)上開放式基金在高聚集性股票群體的羊群效應(yīng)進(jìn)行實(shí)證檢驗(yàn)。檢驗(yàn)機(jī)構(gòu)投資者高聚集性股票間市場(chǎng)間羊群效應(yīng)的程度,并分析和解釋成因。最后對(duì)給出相應(yīng)的政策啟示與建議。
[Abstract]:Herding is often influenced by the majority, and following the masses is also called the "herd effect". People follow what the masses agree, and they don't think about the meaning of events. This effect was first applied in the stock market, and it was originally a term in stock investment. It mainly refers to the phenomenon of investors learning and imitating in the course of trading. This leads them to buy and sell the same shares for a certain period of time. Herding, as an important field of behavioral finance research, combines the advanced theoretical achievements of psychology and behavioral science, and so on, to revise and adjust the hypothesis of "rational man". It successfully explains the market anomalies of intermarket investment convergence and derives a specific empirical model. This paper combines the relevant theoretical knowledge and analytical model of herding effect in behavioral finance. This paper focuses on the herding theory and uses LSV model to test the herding effect of open-end funds in high aggregate stock market in China's A-share market. To test the degree of herding effect in the high concentration stock market of institutional investors, and to analyze and explain the cause of the herding effect. Finally, the corresponding policy implications and suggestions are given.
