摘要


總體經濟環境的變動,會讓投資人心理恐慌,影響投資人的行為,本研究以2008年金融海嘯為分界點,探討金融海嘯前後,投資人情緒是否會對股票報酬造成影響,而在股票類型方面,選擇投機型股票為研究標的,因其報酬起伏明顯,比其他類型股票較能看出差異,以股票報酬波動性及投機特徵判斷投機程度,而在投資人情緒方面,則使用9個單一情緒指標及多變數複合情緒指標,而後9個指標再分成三族群。實證結果,三個族群的情緒指標與股票報酬波動性,在金融海嘯前皆顯示無影響,而在金融海嘯後,三項指標對報酬有顯著的影響;投資人情緒與投機特徵之報酬方面,個別指標有符合假設之情況,以族群來看,金融海嘯前,皆至少有一指標有影響,而金融海嘯後,大型投資人卻無明顯影響。另外,多變數複合情緒指標與報酬波動性、投機特徵之報酬,不論在金融海嘯前後,均無顯著影響。
