Fundamental indices

, developed by Research Affiliates and calculated by FTSE, are known as Research Affiliates Fundamental Index (RAFI). RAFI indices are passively managed market cap indices that use a security weighting system that ranks stocks according to four fundamental value factors. Fundamental indices occupy the Passive security selection/ Fundamental security weighting segnent of the Index Strategy Box (Fig.1).



RAFI indices have also been developed for the bond market, and are calculated in conjunction with Ryan ALM, Inc.

History
Fundamental indexing was developed by Robert Arnott and associates at Research Affiliates, who developed the index security selection and weighting methodologies and researched historical back-tested performance. In 2005, they partnered with index provider FTSE to begin calculating a growing suite of RAFI indices, both for US and international stock markets. The following table shows the historical introduction of RAFI indices.

Research Affiliates was granted a patent on the RAFI methodology on November 18, 2009

In 2010 Research Affiliates laid the methodology groundwork for constructing fundamental bond indices in a paper published in the Journal of Portfolio Management. . On February 10, 2010 Research Affiliates partnered with Ryan ALM, Inc. to construct and calculate a series of RAFI US bond indices.

Characteristics
Fundamental Indexing is the subject of considerable debate among both investment professionals and individual investors.

Security selection and weighting
The construction of a RAFI index begins with the selection of a company universe (for example the FTSE All US All Cap Index, or the FTSE Developed ex US Index) and a screening process that ranks the companies according to four fundamental valuation factors: sales, cash flow, book value, and dividends (see table below). The selection and weighting process is described in detail in the quote box, RAFI Index Construction Rules.

Rebalancing and turnover
In order to preserve proper weighting of companies, fundamental indices are rebalanced once a year. The result is that fundamental indices have higher turnover than do comparable asset class market capitalization indices. In terms of implementation, ETF manager Powershares has managed its RAFI funds with much less turnover than mutual fund manager Schwab.

Returns
The following tables provide investment returns for two broad-based US RAFI indices that have index tracking funds. Given the value tilt of the RAFI index construction, the return series of comparable Russell market and value indexes is provided for comparison.

The following tables provide investment returns for two broad-based International RAFI indices that have index tracking funds. Given the value tilt of the RAFI index construction, the return series of comparable Russell market and value indexes is provided for comparison.

Investment options
RAFI Index funds are available from Charles Schwab (mutual funds) and Powershares ( as ETFs). In June, 2011, Powershares expanded its lineup of RAFI indices by changing the benchmarks of seven ETFs formerly tied to Intellidex Indices to RAFI fundamental indices, and by offering two new RAFI ETFs. PIMCO offers four institutional enhanced RAFI index funds.
