    Abstract: 股票市場睽違已久之『當日沖銷』制度,在證券業者不斷要求下,經證管會、證交所及證券業者多次討論研議後,終於自民國八十三年股市開紅盤日(一月五日)再度實施,惟自實施以來,市場上盛傳對股票之價格機能產生相當之影響,如所謂之『拉尾盤』、『殺尾盤』現象以及當日沖銷將使股價之『震盪幅度』加劇等等。 本研究針對市場上之傳言,以開放當沖前後各一年為研究期間,就大盤、多空頭區間內之震盪幅度採F檢定及並對大小型股之當日高低價差作均數差檢定分析,以驗證當日沖銷之開放,對股票市場價格機能之影響。首先,我們發現開放當日沖銷後,股市當日區間報酬型態與開放當沖前均呈「U」字型態,並發現:『信用交易資券相抵交割』新版當日沖銷制度實施後, 一、股價加權指數之震盪幅度大於實施前。 二、就空頭區間而言,股價加權指數之震盪幅度顯著大於實施前。 三、小型股股價指數之當日高低價差顯著小於實施前。 四、大型股股價指數之當日高低價差幅度顯著大於實施前。
