SPDR Gold Shares (NYSEArca: GLD) was little changed last week and lost ground Friday on European downgrade rumors.

The iShares Silver ETF (NYSEArca: SLV) posted a nice weekly gain as silver prices managed a run above $30 an ounce. Silver tends to display higher volatility than gold prices and is also more linked to the global economy due to silver’s wider industrial uses. [Silver ETFs Give it All Back]

“When people see dips in silver, they are going to get in,” Terry Hanlon, President of Dillon Gage Metals, in a Bloomberg report. “There are more fund managers who are pulling out of the ETFs and buying physical metals, which is a new trend.
