Our original research found that a Fundamental Index® portfolio
outperformed a comparable cap-weighted portfolio of U.S.
large company equities by over 2% annually over the 43 years
tested. A composite of four metrics of economic size is used
in a RAFI® portfolio to improve the long-term performance
of the strategy over using individual measures. |

Subsequent research discovered the Fundamental Index®
methodology advantage extended to smaller company portfolios,
international equities, emerging markets, and even within
economic sectors (technology, health care, consumer, etc.)
of the market.
Equally important, Fundamental Index®
portfolios preserve the original benefits of traditional
capitalization-weighted indexes, including broad diversification,
economic representation, liquidity, scalability, low turnover,
and tax efficiency. Research Affiliates® brings the innovative
Fundamental Index® concept to the marketplace through strategic
affiliations with some of the world’s leading financial institutions.
