jì)算。3.B)0.80解析：根據(jù)資本資產(chǎn)定價(jià)模型（CAPM），預(yù)期收益率=無(wú)風(fēng)險(xiǎn)利率+Beta*（市場(chǎng)風(fēng)險(xiǎn)溢價(jià)）。將公式rearrange得到Beta=(預(yù)期收益率-無(wú)風(fēng)險(xiǎn)利率)/市場(chǎng)風(fēng)險(xiǎn)溢價(jià)。Beta=(0.12-0.02)/0.05=0.10/0.05=2.0。然后，使用Beta和客戶的風(fēng)險(xiǎn)偏好（風(fēng)險(xiǎn)容忍度=(預(yù)期收益率-無(wú)風(fēng)險(xiǎn)利率)/Beta）來(lái)計(jì)算投資組合的Beta?？蛻舻娘L(fēng)險(xiǎn)容忍度=0.10/2.0=0.05。投資組合Beta=客戶風(fēng)險(xiǎn)容忍度/(市場(chǎng)預(yù)期收益率-無(wú)風(fēng)險(xiǎn)利率)=0.05/(0.12-0.02)=0.05/0.10=0.80。4.C)1.18解析：信息比率（InformationRatio,IR）衡量的是風(fēng)險(xiǎn)調(diào)整后的超額收益率，即超額收益率除以跟蹤誤差。超額收益率=投資組合回報(bào)率-基準(zhǔn)回報(bào)率=0.12-0.10=0.02。跟蹤誤差（TrackingError,TE）=1%。IR=超額收益率/跟蹤誤差=0.02/0.01=2.0。注意：題目中的計(jì)算(0.12-0.10)/0.01=1.18實(shí)際上計(jì)算的是夏普比率（SharpeRatio）。信息比率應(yīng)使用跟蹤誤差。若題目意圖確實(shí)是計(jì)算夏普比率，則答案應(yīng)為1.16((0.12-0.02)/0.12)。假設(shè)題目意圖是信息比率，但使用了夏普比率的計(jì)算方法，得到的結(jié)果是1.18。如果嚴(yán)格按信息比率定義，IR=2.0。此處按題目給出的計(jì)算過(guò)程結(jié)果標(biāo)注。修正：根據(jù)定義IR=(PortfolioReturn-BenchmarkReturn)/TrackingError=(0.12-0.10)/0.01=2.0。選項(xiàng)中沒(méi)有2.0，最接近的是C)1.18。可能是題目或選項(xiàng)設(shè)置有誤，或使用了不同的定義/計(jì)算基準(zhǔn)。若嚴(yán)格按照定義IR=2.0，則此題無(wú)正確選項(xiàng)。但根據(jù)常見計(jì)算，夏普比率=1.16。此處按題目給出的計(jì)算過(guò)程結(jié)果標(biāo)注為1.18，并指出其與標(biāo)準(zhǔn)定義的差異。5.C)Itassumesthatallinvestorshavehomogeneousbeliefsaboutfuturereturns,risks,andcorrelations.解析：CAPM的一個(gè)核心假設(shè)是所有投資者對(duì)未來(lái)的預(yù)期收益、風(fēng)險(xiǎn)和相關(guān)性具有相同（同質(zhì)）的信念。這是為了推導(dǎo)出市場(chǎng)組合和風(fēng)險(xiǎn)定價(jià)。現(xiàn)實(shí)世界中，投資者的信念是不同的。6.A)Changesintheoverallmarket.解析：市場(chǎng)因子（MarketFactor）是解釋資產(chǎn)收益波動(dòng)最重要的因子。如果投資組合對(duì)市場(chǎng)因子的敞口（loading）很高，說(shuō)明其收益主要受整體市場(chǎng)行情的影響。高敞口通常與高貝塔系數(shù)相關(guān)。7.C)0.0475解析：投資組合方差=w1^2*σ1^2+w2^2*σ2^2+2*w1*w2*σ1*σ2*ρ12。其中w1=0.50,w2=0.50,σ1=0.20,σ2=0.05,ρ12=0.10。方差=(0.50^2*0.20^2)+(0.50^2*0.05^2)+(2*0.50*0.50*0.20*0.05*0.10)=0.01+0.00125+0.0010=0.01125。標(biāo)準(zhǔn)差=sqrt(0.01125)≈0.1061。方差精確值為0.01125。選項(xiàng)C(0.0475)計(jì)算結(jié)果為0.50^2*(0.20^2+0.05^2)+2*0.50*0.50*0.20*0.05*0.10=0.01225+0.0010=0.01325。選項(xiàng)C的解析有誤，正確方差應(yīng)為0.01125。重新計(jì)算題目給定參數(shù)的方差：0.01125。選項(xiàng)有誤。若按選項(xiàng)C的公式計(jì)算，結(jié)果為0.01325。若題目參數(shù)或選項(xiàng)有誤，此題無(wú)法給出標(biāo)準(zhǔn)答案。假設(shè)題目參數(shù)或選項(xiàng)有誤，但按標(biāo)準(zhǔn)公式計(jì)算結(jié)果應(yīng)為0.01125。8.B)Increasingtheportfolio'sallocationtofloating-ratebonds.解析：浮動(dòng)利率債券的票面利率或收益率會(huì)隨市場(chǎng)利率的變化而調(diào)整，因此其價(jià)格對(duì)利率變化的敏感性（久期）較低，可以有效對(duì)沖利率風(fēng)險(xiǎn)。增加這類債券的配置有助于降低組合的利率風(fēng)險(xiǎn)暴露。9.B)Increasetheexpectedreturnanddecreasethestandarddeviationoftheportfolio.解析：新資產(chǎn)與現(xiàn)有組合呈負(fù)相關(guān)（ρ=-0.50），且其標(biāo)準(zhǔn)差（0.15）小于現(xiàn)有組合（0.10）。根據(jù)投資組合理論，加入一個(gè)與現(xiàn)有組合負(fù)相關(guān)且風(fēng)險(xiǎn)較低的資產(chǎn)，可以降低組合的整體標(biāo)準(zhǔn)差（波動(dòng)性），同時(shí)可能提高預(yù)期回報(bào)（因?yàn)樨?fù)相關(guān)有助于平滑回報(bào)）。具體影響取決于權(quán)重，但加入負(fù)相關(guān)低風(fēng)險(xiǎn)資產(chǎn)通常能降低整體風(fēng)險(xiǎn)。10.B)1.08解析：Sharpe比率=(投資組合回報(bào)率-無(wú)風(fēng)險(xiǎn)利率)/投資組合標(biāo)準(zhǔn)差。Sharpe(PortfolioA)=(0.15-0.02)/0.12=0.13/0.12=1.0833。選項(xiàng)B最接近。PartII:EssayQuestions11.DevelopinganInvestmentPolicyStatement(IPS)isasystematicprocessfordefiningtheparametersofaninvestmentportfoliomanagementrelationship.Thekeystepsinclude:First,conductingathoroughclientassessmenttounderstandtheirfinancialsituation,includingassets,liabilities,andcashflowneeds.Second,definingtheclient'sinvestmentobjectives,whicharetypicallystatedintermsofgoals(e.g.,accumulation,preservation,income)andtimehorizon.Third,identifyingtheclient'srisktolerance,whichreflectstheirwillingnessandabilitytoacceptinvestmentrisk.Fourth,documentingallpolicyconstraints,suchaslegalandregulatoryrestrictions,ethicalconsiderations,liquidityrequirements,andtaximplications.Fifth,establishingthetargetassetallocation,whichspecifiesthedesiredmixofassetclasses(e.g.,equities,fixedincome,realestate)basedontheclient'sobjectives,risktolerance,andconstraints.Sixth,outliningtheinvestmentstrategiestobeemployed,includingthe
