dc.description.abstract (摘要) | 台灣股票市場一直以來以散戶為主要參與者,隨著上市櫃公司家數的大幅成長,如何從龐大數量的個股裡挑選出獲利標的已非易事,加上散戶蒐集與分析資訊的能力有限,因此低成本且易入手的公開資訊,如券商的推薦報告、機構法人的買賣超動態行為等公開資訊,自然成為散戶投資決策的重要參考指標。 本研究採用事件研究法探討外資及國內法人機構發布公開推薦報告之可信度、資訊內涵的多寡、及三大法人買賣超行為與推薦報告之關聯性,希望能提供市場投資者在採納機構法人報告時,更瞭解其背後的實質意義。 研究結果顯示,在強烈買進評等及加碼評等,不論是外資或國內法人機構的報告,皆存在報告發布前外資投資人即先行買進的動作,外資成為股票市場的最大贏家,散戶則承擔了最多損失。在中立評等裡市場對國內法人發布中立評等的報告較偏向正面解讀,對外資機構的建議則真的採取中立態度。在外資及國內法人機構的減碼報告中,平均異常報酬皆有提前下降且維持相當短暫,且外資投資人對外資機構發布的減碼報告信任度極高,但實證結果此時的股市未必如想像中糟糕,外資投資人有過度賣超的疑慮。最後在強烈賣出評等部份,外資報告確實具有一定的資訊內涵,但可能外資於報告發布前已事先布局,股價已對相關資訊有所調整,等到報告發布後大部分的資訊已反應在股價上,使得散戶等到報告出爐再依建議進行買賣股票動作時將產生虧損。 總而言之,外資及國內法人機構發布之推薦報告通常具有一定之資訊內涵,外資投資者更有在報告發布前提前進行策略性布局的動作,因此散戶在參考推薦報告時勿盡然相信其說,避免成為市場上的輸家。 | zh_TW |
