漲跌停前後股價變動行為之實證研究--高頻資料之應用分析 / The empirical study of stock price when it hits price limits --the application of high frequency data

黃麗英, Li-ying Huang Unknown Date (has links)
本篇論文基於市場上所存在的一些交易機制,探討漲跌停前後之股價行為。因為證券市場上存在一些交易規則,例如漲跌停限制、買賣價差、最小升降單位限制、競價制度等,這些交易規則,具有法定的效力,理所當然地會影響投資人的行為。這種以各種交易機制的存在,探討價格形成的過程,就是市場微結構理論之研究範疇。 本篇引用Hausman, Lo, and MacKinlay (1992)所建立之Ordered Probit模型來分析漲跌停前後之股價行為,以個股逐筆交易的價格變動為因變數,而建立因變數為間斷型之分析模型,並以等待撮合時間、交易量、落後期交易價格、買賣價差等經濟變數,來探討個股逐筆交易價格變動的成因。在此同時,鑑於以往研究多假定價量關係為線性,本研究引入非線性的概念,檢定價量之間是否存有非線線性之關係;最後,為使模型更具解釋力,我們引入異質性變異數。 第一章 緒論……………………………………………………………..1 第一節 研究動機……………………………………………..1 第二節 研究目的……………………………………………..7 第三節 研究範圍與限制……………………………………..7 第四節 研究架構與內容……………………………………..8 第二章 文獻回顧……………………………………………………….10 第一節 非同時交易………………………………………….10 第二節 最小升降單位……………………………………….11 第三節 買賣價差…………………………………………….14 第四節 漲跌停限制………………………………………….15 第五節 重要模型回顧…………………………………….…18 2.5.1 Chou(1996)……………………………………..18 2.5.2 Hausman, Lo, and MacKinlay(1992)…………..20 第三章 實證模型設定………………………………………………….25 第一節 資料來源…………………………………………….25 第二節 樣本選取…………………………………………….25 第三節 模型設定…………………………………………….26 3.3.1 價格的變動區間……………………………….26 3.3.2 解釋變數……………………………………….29 3.3.3 條件變異數的型式…………………………….32 3.3.4 價格與成交量之間非線性關係的檢定……….32 第四節 資料處理…………………………………………….33 第四章 實證分析……………………………………………………….36 第一節 模型基本統計分析………………………………….36 第二節 價量非線性關係的檢定…………………………….39 第三節 Ordered Probit模型實證分析……………………….40 第五章 結論與建議……………………………………………………..48 第一節 結論…………………………………………………..48 第二節 建議…………………………………………………..49 參考文獻…………………………………………………………………..50 / This thesis is an application of the market microstructure theory’. In light of some trading mechanisms in our stock market, such as price limit, bid-asked spread, tick size, and auction system, those trading rules would influence the behavior of investors. We want to study the process and outcomes of stock price under those explicit trading rules. We use the Ordered Probit model (Hausman, Lo, and MacKinlay, 1992) to investigate the stock behaviors when it hits price limits. We also use price change as the discrete dependent variable, and time elapsed, trading volume, lag price changes, bid-asked spread as explanatory variables. In order to make the model more explainable, heterogeneity is applied. Moreover, we also want to find out if there is any nonlinear relationship between price change and trading volume.

極端報酬下的交易行為: 三大法人與融資戶 / Trading behavior with extreme return: institutional and individual investors

劉君勇, Liu, Chun Yung Unknown Date (has links)
國內外之研究發現,投資人進行股票交易決策時,存在”關注效果”、”處分效果”、等因素造成投資人產生不理性的投資決策;同時亦有學者指出,台灣市場投資人,不論法人或個體投資人皆存在處分效果,甚至此效果會導致投資造成損失,但鮮少有文章提到面對股價大幅變化時,處分效果是消失還是依然存在。本文主要為探討:極端報酬下,三大法人與融資戶之交易行為差異,是否存在處分效果?又有那些事件會帶來關注效果?本研究使用2001/12/01~2012/3/01之股市交易資料,並透過實證分析發現:(1)極端報酬下,三大法人存在處分效果,融資戶則否(2)股價上漲時,只有外資關注是否有盈餘宣告,而股價下跌時,全體投資人皆會關心盈餘宣告(3)股票觸及漲停價與跌停價,是否造成關注效果,因投資人類型而異(4)儘管三大法人受關注處分效果影響,其交易績效依然優於融資戶。 / Many studies found that “Attention Effect” and “Disposition Effect” will affect investors when they are trading, even make them loss money. In Taiwan stock market, researchers indicate that even institutional investor also affect by disposition effect. But, there is no discussion of when investors trading with extreme return, do they still have the same behavior? This article is going to study how extreme return affect “attention effect” and “disposition effect”. We grab the trading data form 2001/12/01~2012/3/01, by analyzing we find that (1) Only institutional investors affect by “disposition effect”(2) Only foreign investors will pay attention to earning announcement when trading with great appreciation, but all of investors will follow the stock whether it has announce its earning when trading with great depreciation.(3) Whether stock price hit price limit will cause “Attention effect” is depends on which type the investor is.(4) though institutional investors will affect by disposition effect, they still can make access return.
