1、電子科技大學(xué)博士學(xué)位論文基于因素模型的組合投資決策方法研究姓名:馬永開申請學(xué)位級別:博士專業(yè):管理科學(xué)與工程指導(dǎo)教師:唐小我20050620電子科技大學(xué)博士學(xué)位論文策模型(Roll(1992)、馬永開和唐小我(2001)),建立基于基準(zhǔn)組合的多因素證券組合投資決策模型,研究了模型的解和模型控制參數(shù)值的選取問題。在上述研究基礎(chǔ)上,本文嘗試將因素模型引入到組合投資管理決策全過程,即同時將因素模型引入戰(zhàn)略投資決策階段、戰(zhàn)術(shù)投資決策階段和風(fēng)險控制階段,結(jié)合目前發(fā)達(dá)國家金融界興起的一種組合投資風(fēng)險管理新技術(shù)—風(fēng)險預(yù)算技術(shù),建立基于多因素模型的風(fēng)險預(yù)算方法體系。最后
2、,本文對Shefrin和Statman建立的行為證券組合理論從實用性角度進行了拓展性研究,建立了實用的行為證券組合投資決策模型,并將因素模型引入到行為證券組合投資決策模型中,建立了一種只需建立一個價值空間的行為證券組合投資決策模型。關(guān)鍵詞:組合投資管理,單因素模型,多因素模型,基準(zhǔn)組合,風(fēng)險預(yù)算,行為證券組合投資理論摘要AbstractAnewtrendindevelopingmodernportfoliomanagementtheoryistoimprovethetransparenceofriskallocation,whichisalsotheco
