1 Of the three attribution approaches referenced by Tolmach, the method requested by the committee:
选项:
A.is the least accurate.
uses the underlying holdings of the actual portfolio.
is the most difficult and time consuming to implement.
解释:
A is correct.
The committee described a return-based attribution, which is the least accurate of the three approaches (the return-based, holdings-based, transaction-based approaches). Return-based attribution uses only the total portfolio returns over a period to identify the components of the investment process that have generated the returns.
请问基础班上讲过 transaction-based么?
