He then counters these arguments with a careful, non-standard definition of cap-weighted indexing, which distinguishes between the amount of the company being purchased and the amount of money that this purchase costs. He concludes that the argument that cap-weighted indexing is a momentum play is false, as it fails to distinguish between the amount of the company being purchased and the cost of this purchase. It also fails to distinguish between a bet that a portfolio is making relative to the market, and one that is made by the market as a whole. Thus, by defining indexing as the purchase of the same fractional amount of each company, it becomes apparent that indexing is not a momentum play, a size play, nor a style play.}, issn = {1534-7524}, URL = {https://jwm.pm-research.com/content/4/3/46}, eprint = {https://jwm.pm-research.com/content/4/3/46.full.pdf}, journal = {The Journal of Wealth Management} }
