,000/100=10期。市场收益率为6%，即每半年6%/2=3%。债券价格P=Σ[25/(1+0.03)^t](t=1to10)+1000/(1+0.03)^10。计算得P≈926.40。17.c解析思路：债券的duration（久期）衡量的是债券价格对市场利率变化的敏感程度。它表示当利率变化1%时，债券价格预计变化的百分比。久期越长，价格对利率变化的敏感度越高。选项a错误，通常couponrate高的债券，久期较短；选项b错误，maturity长，久期通常也长；选项d错误，duration与yieldtomaturity(YTM)的关系复杂，并非相等。18.d解析思路：降低债券组合的利率风险（久期）的方法之一是immunization，即使组合的久期与其投资期限或目标负债的久期相匹配。其他选项：增加高收益债会增加信用风险；增加平均久期会增加利率风险；多元化行业主要分散行业特定风险。19.d解析思路：看涨期权(CallOption)的盈亏平衡点(Break-EvenPoint)是指股票价格达到何种水平时，期权的买入方开始盈利。盈亏平衡点=行权价+期权费=$50+$2=$52。20.d解析思路：使用期权进行套期保值时，可能会遇到basisrisk（基差风险），即hedgeratio（对冲比率）不稳定；creditrisk（信用风险），如果对手方违约；以及liquidityrisk（流动性风险），尤其是在市场压力下期权或标的资产流动性下降。所有这些风险都可能导致套期保值效果不佳甚至产生损失。21.a解析思路：计算远期合约的盈亏：合约金额*(远期价格-现货价格)=1,000,000欧元*($1.10-$1.15)=1,000,000*(-$0.05)=-$50,000
