台灣證券市場之限價單的研究

詹宜潔, Chain, Yi-Chen Unknown Date (has links)
本研究的研究主題是探討影響台灣投資人使用限價單投資策略的影響因素為何。與歷史文獻不同的是,本研究直接以限價單量的變化來作為應變數,且使用86年台灣證券交易所之市場微資料中之台灣積體電路之資料作為實證來源。 根據文獻間接指出,影響投資人之獲利狀況而可能導致其偏好使用限價單的影響因素有買賣價差之大小,成交量之多寡,投資人士是否具有資訊,與股價波動率大小等等。而根據本研究之實證顯示,限價單量之變化隨著委託時間而呈現遞減的現象,尤其在開盤前的三十分鐘之內達到最大。且本研究發現資料顯示一月份的限價單量相對較大,這可能是由於當年一月份之成交量相對較低的緣故。 至於影響投資人使用限價單之因素方面,實證顯示買賣價差,成交量之大小以及股價波動率與限價單的變化關係密切,且在本研究的模型中,對於限價單量之變化之解釋力高達60%。而在第二部分之實證中顯示,市場上幾乎有90%的限價單量來自散戶,但法人(不包含自營商)的下單行為中卻以限價單居多。不論是法人或散戶皆有出現限價單量隨委託時間而遞減的狀況,而一月份限價單量較多的現象再法人中卻不明顯。 最後,本研究之模型可解釋散戶限價單量變化之情形,但是對於法人之限價單量變化之解釋力卻非常低,這或許是由於法人受到法規的限制無法完全以獲利大小出發點來進行下單行為。

台灣期貨市場快速刪單之研究 —從投資者身分別探討 / A Study of Fleeting Orders in Taiwan’s Futures Markets Across Investor Types

張庭鈞, Zhang,Ting Jun Unknown Date (has links)
本篇論文主要探討台灣期貨市場於2005年至2008年的快速抽單(Fleeting orders)現象。文章將市場交易者區分為機構法人、散戶、自營商以及外資共四類族群,研究抽單背後的動機是否與各族群中交易者的下單積極程度、追價動作,或是降低成交成本有關。實證結果顯示,機構法人在快速抽單動作上無顯著動機;在散戶部分,僅部分散戶具有能力進行快速抽單,而其主要動機是為了降低交易成本。自營商的進場動機,主要是以造市為考量,因此測試市場上是否存在更激進的交易對手單是快速抽單的原因之一。此外,自營商亦會因要降低成交成本而進行快速抽單的動作。由於外資的主要策略是使用波段操作獲取大額利潤,無顯著證據證明外資進行快速抽單的動機是涵蓋於上述三種假設。 本文亦透過實證分析,探討快速抽單與合約報酬的關係,並以研究觀察有較高的快速抽單率是否會帶來較佳報酬,實證結果顯示各族群皆無顯著正相關,但散戶有顯著負相關。四類族群各自有不同的交易型態,故不能將他們概一而論,本篇論文的貢獻即是透過快速抽單,證明四個交易族群在程式交易上,具有不同的策略方向以及對於市場有不同的熟悉程度。 / This paper focuses on the phenomenon of fleeting orders in Taiwan’s futures markets from 2005 to 2008. Traders who in the markets will be divided into local institutional investors, individual, Dealer, and foreign institutional investors. Our study will find the motivation behind fleeting orders under the three hypotheses: attractive, chasing, and the cost-of-immediacy. The empirical results show that local institutional investors have no significant motivation. Only part of individual investors have the ability to use fleeting orders, and their main motivation is to reduce transaction costs. Dealers act as a market maker, so the main motivation for dealers is to raise liquidity. So to test whether a more aggressive limit orders exists in the market is one of the reasons for them to submit fleeting orders. In addition, dealers will also cancel limit orders in order to reduce the transaction costs. Because the main strategy for foreign institutional investors is to obtain a large profit during a period, they have no significant evidence to explain any motivation under the three assumptions. This article also analysis the relationship between fleeting orders and performance, and investigate whether the high fleeting ratio could bring much better profits. The empirical result show that all of four type investors have no significant positive correlation of fleeting orders and performance, but individual investors have significant negative correlation of fleeting orders and performance. Each of four type investors has different trading patterns, so that we should treat them case by case. The contribution of this paper is to prove that the four type investors have different strategies when they use trading program, and they also have different experience in Taiwan’s futures markets.
