【摘要】:券商集合理財(cái)產(chǎn)品已經(jīng)成為我國(guó)金融理財(cái)市場(chǎng)中不可忽視的重要力量,本文運(yùn)用效用無(wú)差別原理對(duì)券商集合理財(cái)產(chǎn)品進(jìn)行定價(jià)研究。在非完備市場(chǎng)和投資者風(fēng)險(xiǎn)厭惡假設(shè)下,結(jié)合最優(yōu)投資策略,利用隨機(jī)控制原理,得出HJB方程,再根據(jù)效用無(wú)差別原理,推導(dǎo)出產(chǎn)品價(jià)格滿足的偏微分方程,并用差分法對(duì)價(jià)格方程進(jìn)行數(shù)值求解。結(jié)果表明:當(dāng)風(fēng)險(xiǎn)厭惡系數(shù)足夠大時(shí),產(chǎn)品效用無(wú)差別價(jià)格隨著封閉期延長(zhǎng)反而降低且;風(fēng)險(xiǎn)態(tài)度僅通過(guò)產(chǎn)品的非系統(tǒng)風(fēng)險(xiǎn)影響產(chǎn)品價(jià)格,若產(chǎn)品與市場(chǎng)相關(guān)性越弱,非系統(tǒng)風(fēng)險(xiǎn)越大,風(fēng)險(xiǎn)態(tài)度對(duì)價(jià)格影響越大,反之亦然,若完全相關(guān),非系統(tǒng)風(fēng)險(xiǎn)為零,風(fēng)險(xiǎn)態(tài)度不對(duì)價(jià)格產(chǎn)生影響;產(chǎn)品價(jià)格與固定管理費(fèi)率和超額收費(fèi)率呈非線性關(guān)系。本文還精確地求解出了產(chǎn)品的系統(tǒng)風(fēng)險(xiǎn)溢價(jià)和非系統(tǒng)風(fēng)險(xiǎn)溢價(jià),并從風(fēng)險(xiǎn)溢價(jià)的角度解釋了價(jià)格隨著產(chǎn)品價(jià)格隨著產(chǎn)品波動(dòng)率增大反而降低這一與B-S公式反常的結(jié)論,最后,根據(jù)固定管理費(fèi)和超額收費(fèi)之間的權(quán)衡關(guān)系,從效用無(wú)差別的角度討論了產(chǎn)品的契約設(shè)計(jì)問(wèn)題。文章的主要內(nèi)容包括以下幾個(gè)方面: 首先,先討論了券商集合理財(cái)產(chǎn)品的契約特性,得出了投資者的收益公式,在完備市場(chǎng)假設(shè)下,投資者根據(jù)金融市場(chǎng)中三種資產(chǎn)進(jìn)行財(cái)富配置,投資者以終止時(shí)刻財(cái)富期望最大化為目標(biāo),選擇最優(yōu)投資策略,,根據(jù)效用無(wú)差別原理,運(yùn)用隨機(jī)控制方法,推導(dǎo)出了產(chǎn)品效用無(wú)差別滿足的偏微分方程,并根據(jù)券商集合產(chǎn)品的契約,得出相應(yīng)的邊界條件。 其次,討論了非完備市場(chǎng)下券商集合理財(cái)產(chǎn)品的定價(jià)問(wèn)題,因?yàn)槿碳侠碡?cái)產(chǎn)品是不可交易的資產(chǎn)且產(chǎn)品管理者必須持有一部分基金份額,致使產(chǎn)品有不可對(duì)沖的非系統(tǒng)風(fēng)險(xiǎn);同樣地,根據(jù)效用無(wú)差別原理,推導(dǎo)出了產(chǎn)品效用無(wú)差別價(jià)格滿足的偏微分方程。 最后,根據(jù)價(jià)值方程,運(yùn)用有限差分方法,進(jìn)行相關(guān)經(jīng)濟(jì)分析,并從效用無(wú)差別的角度討論了產(chǎn)品的契約設(shè)計(jì)問(wèn)題。
[Abstract]:Based on the principle of non - complete market and investor ' s risk aversion , it is concluded that the price of product is less than that of B - S formula . Firstly , the paper discusses the contract characteristics of the wealth management products of the securities trader , and obtains the investors ' income formula . Under the assumption of complete market , the investor chooses the optimal investment strategy according to the three kinds of assets in the financial market , and chooses the optimal investment strategy . According to the principle of non - difference of utility , the partial differential equation satisfying the difference of product utility is derived , and the corresponding boundary condition is obtained according to the contract of the product of the securities trader . Secondly , we discuss the pricing problem of the financial products of the securities traders under the imperfect market , because the financial products of the securities firms are non - tradable assets and the product managers have to hold a part of the fund shares , so that the products have non - systematic risks which are not hedged . Similarly , according to the principle of utility indifference , the partial differential equations which are satisfied by the difference price of the utility of the products are derived . Finally , according to the value equation , the related economic analysis is carried out by using the finite difference method , and the contract design of the product is discussed from the point of difference of utility .
