LONDON, Mar 05, 2012 (Dow Jones) -- ETF Securities' long copper exchange-traded products have recorded their largest combined weekly rise in net holdings since they were listed, after hopes of an economic recovery in the U.S. spurred investor interest in the industrial metal, the London-based ETP provider said Monday.
Additions of $19.9 million were made by investors to ETFS Physical Copper (PHCU.LN) last week, taking total assets under management in the fund--which tracks the physical copper price plus storage costs--to $51.8 million since its listing in late-2010.
Meanwhile, it said $11.3 million has been added to copper futures fund ETFS Copper (COPA.LN). The ETP, which launched in 2006, has recorded $254.1 million of assets under management since its listing.
"With global growth continuing to recover and copper supply-demand fundamentals forecast to continue to tighten, an increasing number of investors are using copper ETPs [to gain] exposure," the company said.
It said expectations of a recovery in Chinese demand, after further monetary easing there, and declining stocks in London Metal Exchange-listed warehouses have helped to boost demand as well.
The company's short copper ETP, however, also recorded inflows last week, totaling $6.4 million after a rise of $7.5 million the week prior.
