grouping companies most likely experiences the highest turnover in its
constituents? Grouping by:
选项：
A.Industry.
Geography.
Statistical similarities
解释：
C is Correct
because company groupings based on statistical similarities tend to have
greater constituent turnover than those based on industries or countries. These
groupings are usually relative (e.g., companies with dividend yields at or
above the 75th percentile as of the measurement date) and tend to
show far more turnover in their constituents than groupings based on industries
and countries, because these statistics are less stable by company and
companies ' rankings change.
