中文摘要 在股票市場中,「價先行量」與「量先行價」的議題,一直廣為實務界與學術界探討。股票價格的上漲或下跌,會受到成交量增加或減少所影響,而成交量來自於機構投資人與散戶的買賣行為。機構投資人買超或賣超與融資或融劵可視為全體法人與散戶投資行為的指標。本研究針對上述資訊連續發生,採用事件研究法(event study)與台灣50成份股作樣本探討之。研究結果如下:
(一)本研究探討的十四類連續事件,均有特定人士在連續事件前買賣股票,為資訊外溢。
(二)機構投資人方面,所有機構投資人連續三天買超,事件日(連續買超的第三天)當天,股價會有正的報酬。當機構投資人連續三天賣超,事件日(連續賣超的第三天)當天,股價會有負的報酬。
(三)成交量方面,成交量連續三天增加,事件日(成交量連續增加的第三天)當天,產生股價向上的趨勢,推動股價上漲。當成交量連續三天減少,事件日(成交量連續減少的第三天)當天,會有股價下跌的現象。
(四)融資與融劵方面,融資連續三天增加或融劵連續三天減少,事件日(連續事件的第三
天)當天,會有股價下跌的現象,而融資連續三天減少與融劵連續三天增加,事件日(連
續事件的第三天)當天,會有股價上漲的現象。
(五)在十四類事件中,在連續事件發生後,只有投信連續三天賣超與融劵連續三天減少兩事件,在事件發生時,不考慮交易成本的前提下買進股票,可以獲利,具有投資價值。
