計(jì)算公式，買方利潤為$15。如果必須選一個(gè)，B是唯一正值選項(xiàng)。*假設(shè)題目或選項(xiàng)有誤，標(biāo)準(zhǔn)計(jì)算為$15利潤。*7.A解析思路：弱式有效市場假設(shè)認(rèn)為，當(dāng)前股票價(jià)格已反映所有歷史價(jià)格和交易量信息，技術(shù)分析無法持續(xù)獲得超額收益。強(qiáng)式有效市場假設(shè)認(rèn)為價(jià)格反映所有公開和內(nèi)部信息，內(nèi)幕交易無效。半強(qiáng)式有效市場假設(shè)認(rèn)為價(jià)格反映所有公開信息（包括財(cái)務(wù)數(shù)據(jù)），基本面分析難以持續(xù)獲得超額收益。選項(xiàng)A描述的是弱式有效市場的觀點(diǎn)。8.D解析思路：根據(jù)CAPM公式：要求回報(bào)率(r)=無風(fēng)險(xiǎn)利率(Rf)+Beta(β)*(市場預(yù)期回報(bào)率(Rm)-無風(fēng)險(xiǎn)利率(Rf))。代入數(shù)據(jù)：r=3%+1.2*(8%-3%)=3%+1.2*5%=3%+6%=9%。選項(xiàng)D的11.6%計(jì)算為：3%+1.2*(8%-3%)=3%+1.2*5%=3%+6%=9%。*此處計(jì)算結(jié)果為9%，選項(xiàng)D11.6%有誤。假設(shè)題目或選項(xiàng)有誤，標(biāo)準(zhǔn)計(jì)算為9%。*9.C解析思路：高收益（Junk）公司債券的發(fā)行人信用風(fēng)險(xiǎn)較高，違約的可能性比投資級債券大，因此被認(rèn)為風(fēng)險(xiǎn)類別更高。TIPS受通脹保護(hù)，風(fēng)險(xiǎn)相對較低。投資級公司債券信用風(fēng)險(xiǎn)較低。機(jī)構(gòu)抵押貸款支持證券通常由政府支持機(jī)構(gòu)擔(dān)保，風(fēng)險(xiǎn)也相對較低。10.C解析思路：貨幣市場基金主要投資于短期、高流動性、低風(fēng)險(xiǎn)的債務(wù)工具，如短期國債、商業(yè)票據(jù)等。其收益率通常與短期市場利率（如國庫券利率）掛鉤。選項(xiàng)A是小盤股，風(fēng)險(xiǎn)較高，波動較大。選項(xiàng)B是長期公司債，風(fēng)險(xiǎn)和期限都較高。選項(xiàng)D是房地產(chǎn)投資信托，風(fēng)險(xiǎn)和流動性相對較低。11.B解析思路：根據(jù)現(xiàn)代投資組合理論，如果新資產(chǎn)與現(xiàn)有投資組合的相關(guān)性低（尤其是負(fù)相關(guān)），將其加入組合可以降低組合的整體風(fēng)險(xiǎn)（方差），并且可能在不增加風(fēng)險(xiǎn)的情況下提高組合的預(yù)期回報(bào)。如果資產(chǎn)與組合完全正相關(guān)，它只會增加風(fēng)險(xiǎn)而不增加預(yù)期回報(bào)。如果資產(chǎn)不提供分散化好處（如與組合完全正相關(guān)），它不會改變組合的風(fēng)險(xiǎn)和回報(bào)。資產(chǎn)對組合風(fēng)險(xiǎn)的貢獻(xiàn)不僅取決于方差，還取決于其與組合的協(xié)方差（或相關(guān)系數(shù)與方差的乘積）。12.B解析思路：歷史成本原則要求資產(chǎn)和負(fù)債按其取得或創(chuàng)建時(shí)的實(shí)際成本進(jìn)行初始記錄和報(bào)告，之后通常根據(jù)成本減去折舊或攤銷來報(bào)告。選項(xiàng)A是會計(jì)基礎(chǔ)，涉及收入和費(fèi)用的配比。選項(xiàng)C是會計(jì)原則，指在存在多種合理選擇時(shí)，應(yīng)選擇最能避免高估資產(chǎn)或收益的方案。選項(xiàng)D是會計(jì)假設(shè)，指除非有確鑿證據(jù)表明公司無法持續(xù)經(jīng)營，否則假設(shè)公司將持續(xù)經(jīng)營下去。13.C解析思路：企業(yè)價(jià)值(EV)=市值+總債務(wù)-現(xiàn)金及現(xiàn)金等價(jià)物。題目未給出現(xiàn)金，通常在一級考試中，若不特別說明，可假設(shè)現(xiàn)金為零或已包含在市值中。EV=$500million+$100million=$600million。選項(xiàng)C正確。14.C解析思路：看漲期權(quán)（Warrant）賦予持有人以特定價(jià)格（執(zhí)行價(jià)）購買標(biāo)的資產(chǎn)的權(quán)利。可轉(zhuǎn)換債券（CallableBond）賦予持有人將債券轉(zhuǎn)換為發(fā)行人股票的權(quán)利，同時(shí)發(fā)行人擁有在特定時(shí)間以特定價(jià)格贖回（調(diào)用）債券的權(quán)利。關(guān)鍵區(qū)別在于期權(quán)賦予的是買入權(quán)，而可轉(zhuǎn)換債券涉及的是債券到股票的轉(zhuǎn)換以及發(fā)行人的贖回權(quán)。15.D解析思路：預(yù)測未來財(cái)務(wù)報(bào)表的過程稱為“預(yù)測”或“前瞻性分析”，最常用的方法是“預(yù)測性財(cái)務(wù)報(bào)表分析”或“管理層預(yù)測分析”。選項(xiàng)A是橫向分析，比較同一公司不同時(shí)期的數(shù)據(jù)。選項(xiàng)B是垂直分析，分析利潤表各項(xiàng)目占銷售額的比重。選項(xiàng)C是共同比分析，將財(cái)務(wù)報(bào)表各項(xiàng)目表示為基準(zhǔn)項(xiàng)目的百分比。SectionB:ItemSetQuestions16.A解析思路：根據(jù)股利增長模型，P1=P0*(1+g)。已知P0=$50,g=5%=0.05。P1=$50*(1+0.05)=$50*1.05=$52.50。17.B解析思路：根據(jù)股利增長模型，股票內(nèi)在價(jià)值P0=D1/(r-g)。其中D1=D0*(1+g)=$2*(1+0.05)=$2.10。r=12%=0.12,g=5%=0.05。P0=$2.10/(0.12-0.05)=$2.10/0.07=$30.00。*此處計(jì)算結(jié)果為$30，選項(xiàng)B$40有誤。假設(shè)題目或選項(xiàng)有誤，標(biāo)準(zhǔn)計(jì)算為$30。*18.C解析思路：如果股票當(dāng)前價(jià)格P0等于內(nèi)在價(jià)值P0(根據(jù)模型計(jì)算)，則隱含的增長率g必須等于要求回報(bào)率r。因?yàn)镻0=D1/(r-g)。如果P0=D1/(r-g)且P0=D1/(r-g)，則r-g=r-g，這意味著g=r。這里D1=D0*(1+g)=$2*(1+g)。所以$50=[$2*(1+g)]/(0.12-g)。$50*(0.12-g)=$2*(1+g)。$6-50g=2+2g。$4=52g。g=$4/52≈0.0769。約等于7.1%。*此處計(jì)算結(jié)果為7.1%，選項(xiàng)C正確。*19.C解析思路：股利增長模型假設(shè)股利以恒定速度增長，適用于那些有穩(wěn)定增長歷史或預(yù)期未來增長穩(wěn)定的公司。該模型不適用于不支付股利或股利不增長的公司（會導(dǎo)致除數(shù)為零或負(fù)數(shù)）。選項(xiàng)A正確描述了其適用性。選項(xiàng)B錯(cuò)誤，要求回報(bào)率必須大于增長rate。選項(xiàng)D錯(cuò)誤，即使假設(shè)成立，市場價(jià)格可能因市場情緒等原因偏離內(nèi)在價(jià)值。20.B解析思路：稅前利潤(EBT)=EBIT-InterestExpense=$200,000-$40,000=$160,000。凈收入(NI)=EBT*(1-TaxRate)=$160,000*(1-0.30)=$160,000*0.70=$112,000。*此處計(jì)算結(jié)果為$112,000，選項(xiàng)B$140有誤。假設(shè)題目或選項(xiàng)有誤，標(biāo)準(zhǔn)計(jì)算為$112。*21.C解析思路：EPS(EarningsPerShare)=(NetIncome-PreferredDividends)/AverageCommonSharesOutstanding。如果優(yōu)先股不是累積的，優(yōu)先股股利如果在當(dāng)年未支付，則不影響當(dāng)期凈利潤計(jì)算。EPS=$112,000/100,000=$1.12。選項(xiàng)C($1.20)是最接近的值。*此處計(jì)算結(jié)果為$1.12，選項(xiàng)C$1.20有誤。假設(shè)題目或選項(xiàng)有誤，標(biāo)準(zhǔn)計(jì)算為$1.12。*22.A解析思路：P/ERatio(Price-to-EarningsRatio)=MarketCapitalization/NetIncome。MarketCapitalization=$1,500,000,NetIncome=$112,000(根據(jù)上一題計(jì)算)。P/E=$1,500,000/$112,000≈13.39。選項(xiàng)A的15.0是最接近的值。*此處計(jì)算結(jié)果為13.39，選項(xiàng)A15有誤。假設(shè)題目或選項(xiàng)有誤，標(biāo)準(zhǔn)計(jì)算為13.39。*23.A解析思路：債券價(jià)格是未來現(xiàn)金流的現(xiàn)值之和。未來現(xiàn)金流包括每半年的利息($1,000*6%/2=$30)和到期償還的面值($1,000)。市場利率是半年期利率(5%/2=2.5%=0.025)。債券還有4期（2年*2）。價(jià)格P=[30/(1.025)^1]+[30/(1.025)^2]+[30/(1.025)^3]+[30/(1.025)^4]+[30+1000/(1.025)^4]。計(jì)算得P≈$970.57+$956.63+$943.35+$930.38+1000=$1,050.92。選項(xiàng)A($1,030.40)是最接近的值。*此處計(jì)算結(jié)果為$1050.92，選項(xiàng)A$1030.40有誤。假設(shè)題目或選項(xiàng)有誤，標(biāo)準(zhǔn)計(jì)算為$1050.92。*24.A解析思路：MacDowell久期是一種常用的近似計(jì)算方法：久期≈(1+y)*[Σ(t*C/P0)]+n*F/P0，其中y是半年期收益率(2.5%),C是半年利息($30),P0是當(dāng)前價(jià)格(~$1030),F是面值($1000),n是剩余期數(shù)(4)。久期≈(1+0.025)*[(1*30/1030)+(2*30/1030)+(3*30/1030)+(4*30/1030)]+4*1000/1030≈1.025*[0.0291+0.0582+0.0873+0.1164]+3845.61/1030≈1.025*0.2910+3.729≈0.298+3.729=4.027。*此處計(jì)算結(jié)果為4.03，選項(xiàng)A1.9有誤。久期通常以年為單位，此處計(jì)算結(jié)果明顯過長，可能
