Update on MSCI Equal Weighted Indices
MSCI Research Bulletin | Dec. 2010
This paper illustrates the effect of equal weighting an index relative to a capitalization weighted index. An equal weighted index exhibits a small cap and value tilt, lower index concentration, and more stable sector weights. However, an equal weighted index has higher index turnover and lower investment capacity relative to a capitalization weighted index. Over the last twelve years (December 1998 to October 2010) the MSCI Equal Weighted Indices outperformed their capitalization weighted counterparts in the major countries and regions analyzed. This outperformance appears to be mainly driven by the small cap and value tilt, which are well-documented sources of excess return in financial literature.
