Charles Schwab (NYSE: SCHW) is the latest exchange traded fund provider to enter the innovative and fast-growing market for fundamentally weighted ETFs that blur the line between active and passive management.

The San Francisco-based financial-services giant on Thursday said it plans to launch six fundamental index ETFs next week. Schwab launched its first ETFs in 2009 and currently manages 15 index-based products. At the end of June, Schwab ETFs had $12 billion in assets under management

The ETFs will track the Russell Fundamental Index Series, which is based on methodology developed by Rob Arnott and Research Affiliates.

Schwab already offers five mutual funds based on the benchmarks, such as Schwab Fundamental US Large Company Index Fund.

Fundamental indices weight individual stocks by economic factors rather than by market capitalization like most traditional equity benchmarks. Fundamental factors include adjusted sales, cash flow, dividends and buybacks.

The fundamental approach “breaks the link between price and weight in the portfolio,” Arnott said during a conference call with reporters on Thursday.

“Some experts believe that because traditional market-cap indexing over-emphasizes popular stocks and de-emphasizes undervalued securities, it can over-expose investors’ portfolios to market speculation, bubbles and fads,” Schwab said in a press release.

“The world is not black and white when it comes to indexing,” added Marie Chandoha, president of Charles Schwab Investment Management.  “We believe the systematic approach inherent in fundamentally weighted methodologies, when used alongside cap-weighted strategies, enables investors to diversify and balance their exposure. These ETFs add a new flavor to our ‘pure vanilla’ ETF market-cap line-up and further demonstrate our commitment to offering core products that help investors build their portfolios and potentially achieve better outcomes.”
