FactorShares, the sponsor that introduced spread trading in an ETF wrapper back in early 2011, launched a new line of ETFs under a new PureFunds brand.  According to the firm’s literature, PureFunds was designed to provide the market with easy access to niche sectors through Pure-Play ETFs.  PureFunds aims to launch tactical ETFs that the market desires but do not currently exist.  The three new ETFs began trading November 29, have expense ratios of 0.69%, share a common prospectus (pdf), and will be assigned to the Materials Sector category of the ETF Field Guide.

Analysis/Opinion: This is not a physically backed diamond ETF.  The prospect of a diamond ETF has been the focus of much media speculation the past year.  I’m on record with my opinion that implementing such a fund could be tricky due to the qualitative nature of valuing gems and lack of futures contracts or other trading vehicles.  GEMS is a unique offering, but it should probably have “producers” or “industry” in its name to avoid being mistaken for a physically backed fund.
