我只写一下第一种可能，第二种可能是重复的。a.按照题目中的投资你会得到一个如下的资产负债表期初资产：1000*20＄（Intel）期末资产：1000*25＄（valueoftotalasset）=25000＄期初负债：5000＄期末负债：5000*（18%）＄（liabilities）=5400＄期初权益：资产—负债=15000＄期末权益=期末资产-期末负债=19600＄期末回报=期末权益—期初权益=19600＄-15000＄=4600＄（netreturnonequity）组合回报率=4600÷15000=0.3066valueoftotalinvestmentequity是你用自己的钱购买的证券（750股）的期末价值，所以等于750*25＄。b.组合权重：资产权重20000÷15000=1.33负债权重-5000÷15000=-0.33资产回报率=（25000-20000）÷20000=0.25负债回报率=（5400-5000)÷5000=0.08组合的净回报率=1.33*资产回报率-0.33*负债回报率=1.33*0.25-0.33*0.08=0.3066检验：4600÷15000=0.3066c.标准差0.18的单位是什么？如果是＄的话。那么组合的标准差=0.18*1000组合的预期收益为460010%*25*1000赞同
