book 4, page260, 第17题和20题的答案是不是相反的啊，我越看越模糊17题答案说: Full replication is likely to have the highest investment cost
19题答案说: Full replication has self-rebalancing properties when used for float-weight index, which would translate into lower transaction fees.
这两个怎么理解？求教各位大牛作者: cloudfengchao 时间: 2013-4-7 14:44
这两种cost不是一个概念：
full replication has highest construction cost (b/c each piece of the index has to be purchased when the replication strategy is initially setup) but lowest rebalance cost (b/c full replication only needs to rebalance when a component get deleted or added to the index)作者: riki930 时间: 2013-4-15 16:37
