Merits Of Equal Weighting An Index

What is the best way to cook an egg?  Scrambled?  Fried?  Poached, perhaps?  That is, of course, an impossible question because the correct answer is completely dependent on what you want the end result to be.

The same is true with index construction.

What is the best way to build an index?  Market cap weighted?  Sector weighted?  Equally weighted?  Or maybe one of the other myriad smart-beta strategies prevalent in the market today?  The right answer depends completely on what you want the characteristics of your finished product, in this case the index, to be.  Are you after lower volatility?  Higher growth?  Broader diversification?

In this paper written by Shane Enete, CFA, with Biola University’s Inspire Research Institute for Biblically Responsible Investing, you will be introduced to the history of indexing, how the “traditional” indexes came to be and why there might be a better way.
