分析師發佈的報告具資訊意涵,本研究欲探討分析師報告中,目標價相對於預測發佈時市價的折溢價比率是否和推薦有著正向的關係,並進一步研究分析師是否會因為個股所屬產業不同,存在不同的推薦門檻,以及分析師報告對於市場是否具有影響力。本研究實證樣本為 2008至2017年的台灣上市櫃企業,發現分析師所發佈的目標價之折溢價比率和推薦為顯著正向關係,易言之,當分析師提供的目標價高於目前市價越多,其於同一時間對該企業出具的推薦報告亦越正向。分析師推薦水準值存在產業差異,平均而言,傳統產業的水準值高於電子產業,電子產業的水準值又高於金融產業,換句話說,金融比電子業獲得較多的推薦,電子又比傳統產業獲得較多的推薦。分析師會因為個股所屬產業不同,存在不同的推薦門檻,門檻高低依序為傳產、電子、金融,給定相同的推薦水準值,傳產須有較高的目標價相對市價之折溢價比率。由分析師出具目標價與推薦報告後的三天累積異常報酬,顯示市場存在過度反應。;There is informative content in analyst’ report. The purpose of this research discuss whether there is a positive relationship between the ratio of target price to market price and the recommendations, and also discuss if there are different thresholds of recommendations when the industry is different, and analysts’ reports are influential.

The level of traditional industry is higher than electronic industry. The level of electronic industry is higher than financial industry.
