SPDR Gold Trust Since bottoming in early November, the SPDR Gold Trust ( ETF ) (NYSE: GLD ) has pressed nearly 8 percent higher and regained its 50-day moving average. The combination of a rising U.S. dollar , falling interest rates and tepid inflationary statistics have not been kind to gold bullion prices or associated mining stocks. More recently, traders have been focused on plunging crude oil and natural gas prices , which has allowed gold the opportunity to make a stealthy move higher.
