QDF had over $507 million in assets under management as of Aug. 1. A company’s ability to generate free cash and dividend growth and stability are integral tenants of the quality factor, making its application practical in dividend ETFs such as QDF.

As the Journal notes, the quality factor is not limited to domestic ETFs. Global markets, both developed and emerging markets, represent growth avenues for index providers and fund issuers on the quality ETF front. Just last month, State Street Global Advisors, the second-largest U.S. ETF issuer, partnered with MSCI on 10 international quality ETFs, including the the SPDR MSCI World Quality Mix ETF (NYSEArca: QWLD), SPDR MSCI EAFE Quality Mix ETF (NYSEArca: QEFA) and the SPDR MSCI Emerging Markets Quality Mix ETF (NYSEArca: QEMM).
