产的权利，而非义务。这是期权的基本定义。b)看跌期权（PutOption）赋予的是卖出权利。c)期权费（Premium）是买方支付的费用，代表其最大潜在损失（若期权未行权），卖方最大潜在收益。d)期权价值受多种因素影响，包括标的资产价格、行权价、剩余时间、波动率等，不仅仅是标的资产价格。15.c解析：私募股权投资（PrivateEquity）通常投资于非上市公司，具有投资期限长、流动性差、信息透明度低、监管要求相对较少等特点。与公募市场投资相比，其最大区别之一是流动性差。16.c解析：有效边界（EfficientFrontier）描绘了在给定风险水平下，预期回报率最高的所有投资组合构成的集合；或者在给定预期回报率下，风险最低的所有投资组合。a)多样化只能分散非系统性风险，不能消除所有风险（包括系统性风险）。b)最优投资组合取决于投资者风险偏好，不一定是最高预期回报。d)贝塔（Beta）衡量的是投资组合的系统风险（与市场相关联的风险），而非非系统性风险。17.d解析：库存周转率=销货成本/平均库存。代入数值：6=$500,000/平均库存。平均库存=$500,000/6=$83,333.33。题目可能意图为$100,000是销货成本。若$100,000是销货成本：库存周转率=$100,000/平均库存。平均库存=$100,000/6≈$16,666.67。若$100,000是平均库存：销货成本=6*$100,000=$600,000。题目数据可能不精确。假设$100,000为销货成本，计算为$d$。若$100,000为平均库存，计算为$600,000。题目未明确，按最常见关系计算，$600,000最符合$100,000是成本或周转率的常见题设。选择$d$。18.c解析：历史成本原则（HistoricalCostPrinciple）要求资产和负债按其取得或形成时的实际成本进行初始记录和报告。这是会计核算的基本原则之一。收入确认原则关注何时确认收入。配比原则关注收入与相关费用的配比。充分披露原则要求披露所有相关信息。19.c解析：E(Rp)=0.40*12%+0.30*10%+0.30*8%=4.8%+3.0%+2.4%=10.2%。最接近的选项是c)10.8%。20.c解析：强式有效市场假说（StrongFormEMH）认为所有信息，包括内幕信息，都已反映在股价中。这意味着无法通过任何信息分析（包括内幕信息）获得超额回报。a)弱式有效市场认为技术分析无效。b)半强式有效市场认为所有公开信息已反映价格，技术分析无效。d)EMH认为，在强式有效市场中，主动管理无法持续跑赢市场。21.b解析：增发新股会稀释现有股东的股权。如果新资本（通过增发获得）能被有效利用，提高公司整体价值和盈利能力，但盈利总额可能不变或变化不大，那么EPS（每股收益）=总盈利/总股本，总股本增加，EPS会下降。a)市值增加不一定与融资额成正比，受市场情绪影响。c)若按面值增发，市值变化取决于市场对新股的定价，可能不变也可能变。d)书面价值/股本可能增加，市值变化导致市值/股本（市场价值）变化。22.b解析：使用自由现金流到股权（FCFE）进行估值，本质上是将未来的FCFE现金流折现到现值，这与DCF模型的核心思想一致，即基于未来预期现金流进行折现估值。DDM基于股利，CCA和Precedent基于可比公司或交易，不直接使用FCFE现金流进行核心折现。23.b解析：对于交易打折（tradingatadiscount）的债券，其市场价格低于面值。由于利息支付基于面值（$1,000），而购买价格低于面值，因此每年的利息收入（$50）占购买价格的比例（$50/市价）会高于利息收入占面值的比例（$50/$1,000=5%）。后者正是债券的到期收益率（YTM），而前者是当前收益率。因此，对于打折债券，当前收益率必然高于到期收益率。*修正：更准确的说法是，对于分期付息债券，当市场价格低于面值时（折价），其计算出的到期收益率（YTM）会高于其当前收益率（CurrentYield）。题目问的是CurrentYield和YTM的关系。CurrentYield=AnnualCoupon/MarketPrice。YTM=(AnnualCoupon+(FaceValue-MarketPrice)/YearstoMaturity)/((FaceValue+MarketPrice)/2)。对于折价债券，MarketPrice<FaceValue，所以YTM包含的正项(FaceValue-MarketPrice)/YearstoMaturity大于0，使得YTM>AnnualCoupon/MarketPrice=CurrentYield。因此，正确答案是b。*24.b解析：CAPM公式中的市场风险溢价（MarketRiskPremium）等于预期市场投资组合的回报率减去无风险利率。a)CAPM假设投资者具有相同的风险厌恶程度，但风险偏好（包括对风险的承受能力）可以不同。c)股票的Beta是相对于市场而言的，不为1意味着其波动性不同于市场。d)CAPM主要用于估计投资的预期回报率，而非直接确定投资公平价值（估值），尽管预期回报是估值的重要输入。25.a解析：在投资组合管理中，添加新资产的决策关键在于其与现有资产的关联性。如果新资产与组合中其他资产的相关性低（甚至是负相关），那么添加该资产可以更好地分散风险，提高组合的效率（即在相同风险下获得更高回报，或相同回报下承担更低风险）。预期回报和标准差是资产的个体特征，更重要的是它们与组合的相互作用。价格-收益比是估值指标。26.c解析：普通股（CommonStock）代表对公司的所有权份额，当公司发行新股或通过留存收益增加资本时，普通股的账面价值会增加，这代表公司所有者权益的增加，是公司获得现金（或资产）并转化为所有者权益的一种方式。其他选项，应付账款是负债，折旧是非现金费用，留存收益是权益的组成部分，但不是直接的外部现金流入。27.c解析：首先计算年销货成本（COGS）=5*平均库存=$500,000。然后计算应收账款周转率=年销货成本/平均应收账款。已知DSO=40天，DSO=365天/应收账款周转率。应收账款周转率=365/40=9.125次。平均应收账款=年销货成本/应收账款周转率=$500,000/9.125≈$54,795.76。最接近的选项是$c$$200,000。*注意：计算结果约为$54,796，与选项$c$$200,000差异较大。题目数据或选项可能存在问题。若按$200,000计算，则周转率=$500,000/$200,000=2.5次。DSO=365/2.5=146天。这与40天相差甚远。题目数据不一致。*28.c解析：WACC计算中，债务成本需要考虑税收影响，因为利息支出在税前扣除可以减少公司税负。因此，使用（1-税率）对债务成本进行调整，以反映税盾效应。a)WACC包含权益和债务成本。b)市场价值权重通常更准确，但书价值权重有时也使用。d)WACC会因公司不同而异，取决于其资本结构和税负。29.c解析：市场时机（MarketTiming）策略试图通过预测市场短期走势，在市场上涨前买入，下跌前卖出，从而获得超额回报。这种策略直接利用市场短期无效性或波动性来获利，因此最符合利用市场无效性获取超额回报的描述。价值投资基于基本面低估，指数化是被动策略。30.a解析：夏普比率（SharpeRatio）是衡量投资组合风险调整后回报的指标，计算公式为（投资组合超额回报率/投资组合标准差）。它表示每单位总风险（以标准差衡量）能带来多少超额回报
