问题如下：
Which type of market participant is most likely to consistently express risk measures as a percentage of assets and relative to a benchmark?
选项：
A.Banks
B.
Corporations
C.Long-only asset managers
解释：
C is correct. Long-only asset managers most commonly express risk measures in percentage terms and relative to a benchmark, whereas the entities in answers A and B measure risk more commonly in currency units and in absolute terms
(not relative to a benchmark). Banks occasionally express risk measures, such as economic capital, as a percentage of assets or other balance sheet measures, but bank risk measures are typically expressed in currency units.
老师好， Long-only asset managers most commonly express risk measures in percentage terms and relative to a benchmark 是不是也是active share的意思？ 谢谢。
