適當(dāng)?shù)淖龇ㄊ蔷芙^這次旅行。2.a解析思路：道德準(zhǔn)則要求會員在提供投資建議時必須勤勉盡責(zé)（Diligence）。這意味著會員需要執(zhí)行適當(dāng)?shù)谋M職調(diào)查和分析，以確保其建議是合理的。在本例中，如果股票表現(xiàn)不佳，而經(jīng)理無法提供令人信服的理由來解釋其分析或建議，則表明其可能沒有履行勤勉盡責(zé)的義務(wù)。雖然客觀性（c）和忠誠（d）也很重要，但經(jīng)理未能解釋其分析的根本原因，直接反映了其在盡職調(diào)查方面的不足。3.b解析思路：根據(jù)CFA協(xié)會道德準(zhǔn)則，會員有責(zé)任披露可能影響其客戶或公眾利益的重要信息。如果研究發(fā)現(xiàn)可能存在財務(wù)報表操縱，即使存在法律風(fēng)險，也必須采取行動。將發(fā)現(xiàn)報告給公司的法律部門和合規(guī)部門（b）是正確的做法。這允許公司評估情況，采取適當(dāng)?shù)男袆?，并確保合規(guī)性。僅僅發(fā)表報告（a）或撤回報告（c）或修改發(fā)現(xiàn)（d）都可能導(dǎo)致違反道德準(zhǔn)則或法律義務(wù)。4.b解析思路：預(yù)期回報是各項資產(chǎn)回報的加權(quán)平均值：E(Rp)=wA*E(RA)+wB*E(RB)=0.6*12%+0.4*8%=7.2%+3.2%=10.8%。組合的標(biāo)準(zhǔn)差計算公式為：σp=sqrt[wA^2*σA^2+wB^2*σB^2+2*wA*wB*σA*σB*ρ(A,B)]=sqrt[(0.6^2*15^2)+(0.4^2*10^2)+2*0.6*0.4*15*10*0.4]=sqrt[(0.36*225)+(0.16*100)+(2*0.6*0.4*15*10*0.4)]=sqrt[81+16+36]=sqrt[133]≈11.527。選項中最接近的是9.8%，這表明計算中可能使用了不同的權(quán)重或近似值，或者題目本身或選項存在偏差?；跇?biāo)準(zhǔn)公式計算結(jié)果約為11.53%，沒有選項完全匹配。但題目要求選擇“最”合適的，考慮到標(biāo)準(zhǔn)公式和計算結(jié)果，選項B(10.8%,9.8%)可能是在特定情境或近似下的預(yù)期答案。5.a解析思路：信息比率（InformationRatio,IR）是excessreturn的標(biāo)準(zhǔn)差除以excessreturn。ExcessReturn=ActualReturn-BenchmarkReturn。ManagerX的excessreturn標(biāo)準(zhǔn)差=8%,ManagerY的excessreturn標(biāo)準(zhǔn)差=7%。ManagerX的excessreturn=15%-12%=3%,ManagerY的excessreturn=14%-13%=1%。信息比率IR=(ExcessReturn)/(StandardDeviationofExcessReturn)。ManagerX的IR=3%/8%=0.375。ManagerY的IR=1%/7%≈0.143。因此，ManagerX的信息比率更高，表現(xiàn)更好。6.b解析思路：根據(jù)CAPM，預(yù)期回報E(Ri)=Rf+βi*[E(Rm)-Rf]。代入數(shù)據(jù)：E(Rp)=5%+1.2*(12%-5%)=5%+1.2*7%=5%+8.4%=13.4%。Alpha=實際回報-根據(jù)CAPM計算的預(yù)期回報=14%-13.4%=0.6%。因此，alpha是0.6%。選項中沒有0.6%，最接近的是1.0%?？赡艽嬖陬}目數(shù)據(jù)或選項設(shè)置的問題。但基于計算，0.6%是正確結(jié)果。7.a解析思路：特征線（CharacteristicsLine,CL）的斜率表示投資經(jīng)理的績效相對于基準(zhǔn)的主動風(fēng)險調(diào)整后回報。正斜率意味著投資經(jīng)理的回報高于基準(zhǔn)回報，且隨著基準(zhǔn)回報的增加而增加，表明經(jīng)理產(chǎn)生了正的alpha。正截距表示即使投資經(jīng)理的回報與基準(zhǔn)回報完全一致（斜率為零），其回報也高于無風(fēng)險回報率，這在有效市場中通常不成立，但正截距本身并不直接衡量一致性。關(guān)鍵在于正斜率表明了超越基準(zhǔn)的積極貢獻(xiàn)。題目描述的“正斜率和正截距”最可能指向的是經(jīng)理產(chǎn)生了正alpha，并且（或）回報與基準(zhǔn)有一定正相關(guān)性。選項（a）準(zhǔn)確描述了正斜率意味著超越基準(zhǔn)的回報，而“高度相關(guān)”可能反映了題目設(shè)定的情景，即使不完全精確，也是對正斜率的最佳解釋。其他選項（b:負(fù)截距/alpha,c:負(fù)斜率/underperformance,d:負(fù)斜率/低相關(guān)性）都與描述不符。8.a解析思路：ValueatRisk(VaR)定義了在給定的置信水平下，投資組合在特定時間段內(nèi)可能遭受的最大損失。例如，1天95%VaR為$500,000意味著有95%的可能性，在1天內(nèi)損失不會超過$500,000。因此，最大可能損失（以95%的置信度）就是VaR值本身，即$500,000。9.c解析思路：添加新資產(chǎn)對組合風(fēng)險（標(biāo)準(zhǔn)差）的影響取決于該資產(chǎn)與現(xiàn)有組合的相關(guān)性。計算新組合的標(biāo)準(zhǔn)差需要知道所有資產(chǎn)的比例和協(xié)方差/相關(guān)系數(shù)。公式為σp_new=sqrt[Σ(wi^2*σi^2)+2*Σ(wi*wj*Cov(i,j))]或σp_new=sqrt[Σ(wi^2*σi^2)+2*Σ(wi*wj*σi*σj*ρ(i,j))].由于題目只提供了兩個資產(chǎn)的相關(guān)性（0.25），以及它們各自與*現(xiàn)有*組合（未定義）的相關(guān)性，無法計算整個新組合的標(biāo)準(zhǔn)差。僅憑AssetA和AssetB之間的相關(guān)性無法確定新組合的整體風(fēng)險變化。如果ρ=0.25，理論上新組合風(fēng)險可能降低，但具體數(shù)值取決于權(quán)重和現(xiàn)有組合的細(xì)節(jié)。因此，無法僅憑現(xiàn)有信息確定對整體風(fēng)險的明確影響。10.b解析思路：添加資產(chǎn)以降低組合風(fēng)險，需要選擇與現(xiàn)有組合低相關(guān)性的資產(chǎn)。資產(chǎn)1和資產(chǎn)2的相關(guān)系數(shù)為0.6，這是一個正的相關(guān)性，意味著它們在一定程度上同向變動，添加它們可能不會顯著降低現(xiàn)有組合的風(fēng)險，甚至可能增加風(fēng)險（如果權(quán)重不當(dāng)）。資產(chǎn)2的標(biāo)準(zhǔn)差（14%）低于資產(chǎn)1的標(biāo)準(zhǔn)差（18），且相關(guān)系數(shù)相同，通常情況下，標(biāo)準(zhǔn)差更低的資產(chǎn)（在相關(guān)性相近時）為組合帶來的風(fēng)險增量可能更小。因此，從降低風(fēng)險的角度看，資產(chǎn)2可能比資產(chǎn)1更具吸引力。選項（c）和（d）均不正確。選項（a）認(rèn)為資產(chǎn)1更好，與降低風(fēng)險的邏輯相反。11.c解析思路：私募股權(quán)（PrivateEquity）投資通常投資于未上市的公司，流動性很低，投資期限較長（通常3-7年），且風(fēng)險較高，期望回報也較高。它們受到的監(jiān)管相對較少，尤其是在投資策略和信息披露方面，與受SEC監(jiān)管的公開市場投資不同。選項（a）錯誤，流動性低。選項（b）錯誤，通常期望較高回報。選項（d）錯誤，主要投資于非上市公司。12.b解析思路：采用多空股票策略（long/shortequity）的對沖基金旨在通過同時做多看好的股票和做空看壞的股票來獲取絕對回報，力求減少市場整體波動對其收益的影響。這種策略的目的是生成相對穩(wěn)定的回報，其回報與市場指數(shù)的相關(guān)性通常較低（b）。選項（a）過于絕對，市場條件不利時也可能虧損。選項（c）錯誤，對沖基金通常監(jiān)管較少。選項（d）正確，投資門檻高，面向合格投資者。13.b解析思路：房地產(chǎn)投資信托（REIT）是一種將大部分應(yīng)稅收入（通常是90%或以上）分配給股東的實體。為了獲得稅收優(yōu)惠（避免作為公司雙重征稅），REIT必須進(jìn)行這種高比例分配。REIT通常投資于房地產(chǎn)，并提供相對較高的股息收益率，使其對尋求收入的投資者有吸引力，但風(fēng)險也相對較高，不完全等同于保守投資。選項（a）錯誤，REIT仍需繳納聯(lián)邦所得稅（但可抵扣運營損失）。選項（c）錯誤，REIT主要投資于房地產(chǎn)相關(guān)資產(chǎn)，不能主要投資于股票和債券。選項（d）錯誤，REIT必須公開披露財務(wù)信息。14.c解析思路：損失厭惡（LossAversion）是指投資者在同等數(shù)量的盈利和虧損面前，感受到的損失帶來的痛苦遠(yuǎn)大于盈利帶來的快樂。本例中，投資者傾向于“賣掉”虧損的股票（鎖定損失，減輕痛苦），而“持有”盈利的股票（希望進(jìn)一步盈利，避免潛在的盈利回吐）。這種行為模式完全符合損失厭
