第五章 結論與建議
第二節 對後續研究者的建議
本研究對後續研究者提供下列的研究建議：
一、 本研究以公司在證交所公開資訊觀測站正式宣告財測調整資訊的 時點向前追溯三個月內首次報載的財測相關報導為最有可能的未知 資訊；然而，由於有些公司的第一次媒體報導事件日是發生在此公 開資訊觀測站正式宣告日前三個月更早的期間，所以後續研究者可 以延長前述的追溯期間。
二、 建議後續的研究者深入探討投資人產生認知失調的原因。
三、 由於本研究的實證結果指出，投資人對財測更新相關資訊有處份效 果，所以建議後續的研究者可以進一步結合處份效果與認知失調進 行深入的探討。
四、 建議後續的研究者依據調升與調降財測的幅度高低，調查股價、交 易量與波動性效果的差異。
五、 由於本研究發現部分公司的正式宣告調整財測前三個月內無相關 的媒體報導，因此建議後續的研究者可以進一步比較正式宣告前有 相關媒體報導與無相關媒體報導的股價、交易量與波動性效果差 異。
