full replication. 书上原题. full replication 可以减少rebalancing cost. 题目要求的是minimize rebalancing cost 不是 transaction cost
有一个题 indexing strategy 是选optimization还是stratified?
the objective is to minimize transaction cost and tracking error in the same time。
optimization minimizes tracking error but has large transaction cost。
stratified has moderate t-cost and tracking error。
我原来选stratefied后来改称optimization,现在想想还是stratify对。
Actually, t-cost and tracking error is a trade-off and cannot be minimized simultaneously。
one possible method is to use an objective function as a weighted sum of t-cost and tracking error。

你没算后两个阿 1,2 year future is correctly priced but 3,4 year future is under priced. Long future, short spot -> borrow from central bank
