收益率，即超额收益率除以跟踪误差。超额收益率=投资组合回报率-基准回报率=0.12-0.10=0.02。跟踪误差（TrackingError,TE）=1%。IR=超额收益率/跟踪误差=0.02/0.01=2.0。注意：题目中的计算(0.12-0.10)/0.01=1.18实际上计算的是夏普比率（SharpeRatio）。信息比率应使用跟踪误差。若题目意图确实是计算夏普比率，则答案应为1.16((0.12-0.02)/0.12)。假设题目意图是信息比率，但使用了夏普比率的计算方法，得到的结果是1.18。如果严格按信息比率定义，IR=2.0。此处按题目给出的计算过程结果标注。修正：根据定义IR=(PortfolioReturn-BenchmarkReturn)/TrackingError=(0.12-0.10)/0.01=2.0。选项中没有2.0，最接近的是C)1.18。可能是题目或选项设置有误，或使用了不同的定义/计算基准。若严格按照定义IR=2.0，则此题无正确选项。但根据常见计算，夏普比率=1.16。此处按题目给出的计算过程结果标注为1.18，并指出其与标准定义的差异。5.C)Itassumesthatallinvestorshavehomogeneousbeliefsaboutfuturereturns,risks,andcorrelations.解析：CAPM的一个核心假设是所有投资者对未来的预期收益、风险和相关性具有相同（同质）的信念。这是为了推导出市场组合和风险定价。现实世界中，投资者的信念是不同的。6.A)Changesintheoverallmarket.解析：市场因子（MarketFactor）是解释资产收益波动最重要的因子。如果投资组合对市场因子的敞口（loading）很高，说明其收益主要受整体市场行情的影响。高敞口通常与高贝塔系数相关。7.C)0.0475解析：投资组合方差=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。标准差=sqrt(0.01125)≈0.1061。方差精确值为0.01125。选项C(0.0475)计算结果为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。选项C的解析有误，正确方差应为0.01125。重新计算题目给定参数的方差：0.01125。选项有误。若按选项C的公式计算，结果为0.01325。若题目参数或选项有误，此题无法给出标准答案。假设题目参数或选项有误，但按标准公式计算结果应为0.01125。8.B)Increasingtheportfolio'sallocationtofloating-ratebonds.解析：浮动利率债券的票面利率或收益率会随市场利率的变化而调整，因此其价格对利率变化的敏感性（久期）较低，可以有效对冲利率风险。增加这类债券的配置有助于降低组合的利率风险暴露。9.B)Increasetheexpectedreturnanddecreasethestandarddeviationoftheportfolio.解析：新资产与现有组合呈负相关（ρ=-0.50），且其标准差（0.15）小于现有组合（0.10）。根据投资组合理论，加入一个与现有组合负相关且风险较低的资产，可以降低组合的整体标准差（波动性），同时可能提高预期回报（因为负相关有助于平滑回报）。具体影响取决于权重，但加入负相关低风险资产通常能降低整体风险。10.B)1.08解析：Sharpe比率=(投资组合回报率-无风险利率)/投资组合标准差。Sharpe(PortfolioA)=(0.15-0.02)/0.12=0.13/0.12=1.0833。选项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
