答:
(1)到期本利和=10010%2+100=120(元)
(2)最终实际收益率=(到期收回的本利和—认购价格)/偿还年限/认购价格100%
=(120-102)/2/102100%
=8.82%
或:最终实际收益率=[年利息+(面额—认购价格)/偿还年限]/认购价格100%
=[10010%+(100-102)/2]/102100%
=8.82%
(3)持有期间收益率=(卖出价—购入价)/持有年限/购入价100%
=(108-102)/1/102100%
=5.88%
(4)到期收益率=(到期的本利和—购入价)/残存年限/购入价100%
=(120—108)/1/108100%
=11.11%
