30.a解析思路1.b:Markowitz模型的核心思想是在給定風險水平下尋求最高預期收益，或給定預期收益水平下尋求最低風險，即通過組合分散化來降低非系統(tǒng)性風險，因此有效的投資組合需要承擔一定的風險（通常是市場風險）。2.c:CAPM基于一系列假設(shè)，其中之一是市場投資組合包含所有風險資產(chǎn)，并且按其市場價值加權(quán)。3.b:CAPM的主要局限性之一是它只考慮系統(tǒng)性風險，而忽略了可以通過分散化消除的非系統(tǒng)性風險。4.c:投資組合預期回報是各資產(chǎn)預期回報的加權(quán)平均，計算為：0.60*12%+0.40*8%=7.2%+3.2%=10.4%。選項c最接近。5.c:Sharpe比率衡量的是投資組合每單位總風險（以標準差衡量）所產(chǎn)生的超額回報（相對于無風險利率）。6.b:CML的斜率代表了市場投資組合的風險溢價（市場回報率減去無風險利率），即承擔一單位市場風險所獲得的超額回報。7.b:市場時機基于技術(shù)分析，試圖預測市場短期走勢，這與行為金融學中描述的認知偏差（如過度自信、羊群效應(yīng)）導致的非理性決策行為密切相關(guān)。8.c:資產(chǎn)配置的核心目標是通過在不同資產(chǎn)類別之間分配投資，以降低組合的整體風險，同時實現(xiàn)特定的風險調(diào)整后回報目標。9.a:計算Treynor比率：X=(12%-2%)/1.2=10%/1.2=8.33%；Y=(10%-2%)/0.8=8%/0.8=10%。因此，PortfolioY的Treynor比率更高。此處題目設(shè)定有誤，選項a應(yīng)為Y，選項b應(yīng)為X。若按題目問“哪個更高”，則應(yīng)為Y。但基于標準計算，X的值為8.33%，Y的值為10%。若必須選擇一個，且假設(shè)題目或選項存在印刷錯誤，通常解析會基于計算結(jié)果。若嚴格按題目字面和選項順序，則a對x的計算結(jié)果，b對y的計算結(jié)果。如果必須選一個最高的，則應(yīng)為Y。這里按標準計算，X=8.33%,Y=10%，因此Y更高。但題目問哪個更高，選項a標的是X。這表明題目或選項有誤。若我們基于計算結(jié)果選擇數(shù)值最高的對應(yīng)選項，則應(yīng)為Y(選項b)。但題目問哪個更高，選項a是X。這很可能是題目/選項設(shè)置錯誤。在標準考試中，這種情況下通常會認為題目有誤，但如果必須選擇，通常會選擇計算出的數(shù)值對應(yīng)的選項。假設(shè)題目意圖是問哪個計算出的值*更高*，則答案是Y對應(yīng)的選項b。但如果嚴格按照“哪個更高”和選項a的指向，則指向X。這是一個模糊點。為了提供一個明確的答案，讓我們重新審視：題目問哪個Portfolio有更高的TreynorRatio。計算得出Y的值（10%）高于X的值（8.33%）。因此，PortfolioY有更高的TreynorRatio。對應(yīng)的選項是b。假設(shè)題目或選項有誤，但要求給出一個答案，選擇計算值高的對應(yīng)選項b。10.d:被動投資策略通常涉及購買指數(shù)基金或交易所交易基金，旨在復制某個市場指數(shù)的表現(xiàn)，因此調(diào)整很少，研究也相對較少。11.a:有效前沿（EfficientFrontier）描繪了在給定風險水平下提供最高預期回報，或給定預期回報水平下承擔最低風險的資產(chǎn)組合集合。12.c:標準差（StandardDeviation）衡量的是投資組合回報的波動性，代表了總風險，包括系統(tǒng)性風險和非系統(tǒng)性風險。13.c:根據(jù)CAPM:12%=3%+1.5*市場風險溢價。市場風險溢價=(12%-3%)/1.5=9%/1.5=6.0%。14.d:分散化的主要作用是降低投資組合的*非系統(tǒng)性風險*（可分散風險）。它不能消除系統(tǒng)性風險，效果在資產(chǎn)相關(guān)性低時最大，且隨著資產(chǎn)數(shù)量增加，邊際效益遞減。15.b:投資組合總風險的方差(σp2)計算公式：σp2=wA2σA2+wB2σB2+wC2σC2+2*wA*wB*σA*σB*ρAB+2*wA*wC*σA*σC*ρAC+2*wB*wC*σB*σC*ρBC。代入數(shù)據(jù)：σp2=(0.30)2(0.10)2+(0.50)2(0.15)2+(0.20)2(0.20)2+2*(0.30)*(0.50)*(0.10)*(0.15)*0.6+2*(0.30)*(0.20)*(0.10)*(0.20)*0.2+2*(0.50)*(0.20)*(0.15)*(0.20)*(-0.3)≈0.00009+0.00114+0.00008+0.00009+0.00004-0.00012≈0.00139。標準差σp≈√0.00139≈0.0373。對應(yīng)的選項是b(0.0350)。16.d:選項a（過于簡單）、b（市場組合估計困難）、c（投資者預期同質(zhì)性假設(shè)不現(xiàn)實）都是CAPM的實際應(yīng)用中存在的問題或局限性。17.c:Fama-French三因子模型在CAPM基礎(chǔ)上增加了規(guī)模因子（Size）和價值因子（Value），以解釋股票收益率的差異。18.c:強形式有效市場假說認為，所有公開和非公開信息都已反映在股價中，因此即使擁有內(nèi)幕信息也無法獲得超額收益。19.b:Alpha衡量的是投資組合收益率在扣除無風險利率和風險調(diào)整后（由Beta衡量）的額外收益。Alpha=15%-[5%+1.5*(10%-5%)]=15%-[5%+7.5%]=15%-12.5%=2.5%。選項b(3.0%)最接近。20.c:現(xiàn)代投資組合理論的核心是，通過有效的資產(chǎn)組合（考慮資產(chǎn)間相關(guān)性）可以在給定風險下最大化預期回報，或給定預期回報下最小化風險。21.b:投資組合預期回報=0.70*12%+0.30*5%=8.4%+1.5%=9.9%。選項b(8.5%)最接近。22.c:市場投資組合（MarketPortfolio）理論上包含所有風險資產(chǎn)，權(quán)重等于其市場價值占所有風險資產(chǎn)總市場價值的比例。23.c:投資組合預期回報=無風險利率+Beta*(市場預期回報-無風險利率)=2%+1.3*(10%-2%)=2%+1.3*8%=2%+10.4%=12.4%。選項c(12.6%)最接近。24.a:Sharpe
