Based upon Dewey’s chosen investment process for the management of the Purity Fund,rebalancing of the fund will most likely occur:

选项：

at regular intervals

in response to changes in company-specific information

in response to updated output from optimization models

解释：

B is correct. Managers using an active fundamental investment process, like Dewey’s, usually monitor the portfolio’sholdings continuously and may rebalance at any time. In contrast, portfolios using a quantitative approach are usually rebalanced at regular intervals, such as monthly or quarterly, or in response to updated output from optimization models. A is incorrect because portfolios using a quantitative (not fundamental) active approach are usually rebalanced at regular intervals, such as monthly or quarterly. C is incorrect because construction of a quantitative portfolio (not a fundamental portfolio) typically involves using a portfolio optimizer, which controls for risk at the portfolio level in arriving at individual stock weights and leads to rebalancing decisions.
