One look at gold exchange traded funds (ETFs) will tell you this much: investors love their physically-backed metal funds. If certain providers have their way, there could be a lot more to love soon.

Now that precious metal ETFs have been covered by such funds as SPDR Gold Shares (NYSEArca: GLD), iShares Silver Trust (NYSEArca: SLV) and ETFS Physical Platinum (NYSEArca: PPLT), the industry is setting its sights on industrial metals. [ETF Assets Hit a Milestone, Thanks to Gold.]

Cinthia Murphy for Index Universe reports that the change is part of an ongoing strategy to eliminate exposure to U.S. stocks and focus instead on commodities, particularly precious metals, in part to protect investors from a falling dollar.
