最佳五檔資訊內涵

陳筑音 Unknown Date (has links)
台灣證券集中市場自民國92年1月2日開始實施最佳五檔買賣價量資訊的揭露,提高了市場的透明度,而盤中五檔資訊的揭露,投資人得以從中觀察到委託單的分布狀態,降低了資訊不對稱的情形;倘能藉由分析流動性投資人在每盤撮合後,觀察行情揭示的最高五檔買進與最低五檔賣出價量資訊,並將決策行為反映於市場時,其投資行為是否具有預測未來價格的功能,並探討流動性投資人是否存在一窩蜂行為,以及某一支股票的行為是否會受到對其他股票感染,期能藉由五檔資訊的分析與驗證,以供投資大眾之參考。 本文利用台灣證券集中市場上市公司進行實證研究,結果發現,經由五檔資訊所獲得之市價買單、市價賣單及前一盤報酬資訊,對於未來報酬具有預測能力,且流動性投資人具有一窩蜂出現的情形;此外,市價買、賣單會受到前一盤市價買、賣單影響,因而具有持續性現象;股票間的流動性買壓是否互具感染性則未獲有力支持;最後發現,揭露最佳五檔政策實施後,使股票市場的波動性減小,顯示由於資訊透明化,有助市場的交易效率的提升與減少資訊不對稱現象,該政策的實施有正面的意義。 / Since January 2nd, 2003, the Taiwan Stock Exchange Corporation (TSEC) started to disclose the information of the best five bids/asks and volumes. The disclosure of the best five bids/asks and volumes enhances the pre-trade transparency. With the disclosure , investors will get more information to help the decision making. This paper employs the intraday five asks/bids and volumes of the Taiwan stock exchange to analysis the liquidity traders’ investments. According to the experiments, we first find the predictive power of the market orders and lag return. However, we don’t demonstrate that the liquidity buying pressure can predict the future return. Besides, we also find that liquidity traders are likely to arrive at the market together (commonality) .
