dc.description.abstract | 本文以2006年至2011年之外資分析師報告為研究樣本,並以事件研究法做為主要之研究方法。主要目的是探討外資評等報告是否具有資訊內涵,以及外資評等報告發佈前,是否存在資訊交易之現象。實證結果發現,無論是買進評等或賣出評等,在報告宣佈當天及前幾天對股價都有相對較大的影響,代表分析師報告存在資訊內涵。在事件日的前一個營業日也可觀察到外資買賣的顯著程度明顯高於除了事件日的其他時間。此外,相對於重申買進和重申賣出,無論是調升買進評等或調降賣出評等對外資買賣都有相對較大的影響,代表外資機構投資人在事件日前幾日之股票買賣與分析師報告內容有關。綜合以上結果,本文認為外資分析師報告存在提前揭露給特定外資機構投資人的現象,而且這些特定外資機構投資人也會根據分析師報告的內容調整股票部位。 | zh_TW |
dc.description.abstract | This paper studies the trading of foreign institutions immediately before the release of analysts’ buy and sell recommendations. We document abnormally high foreign institutional trading volume beginning two days before recommendations are publicly released. Abnormal trading is related to recommendation characteristics that would require knowledge of the content of the report – such as whether the recommendation is upgrade or downgrade. Our results are consistent with institutional traders receiving tips regarding the contents of forthcoming analysts’ reports. | en_US |
