Gold prices have pulled back this month with equities, raising questions over the metal’s safe-haven status as investors sell gold to cover losses elsewhere.

“It’s not behaving the way bulls would like it to behave,” said Matthew Turner of Mitsubishi Corp. in a Reuters report. “There are enormous macro issues in Europe, the U.S. and China and we don’t know how it will pan out. It’s uncertainty on top of uncertainty, and a lot of people are standing on the sidelines.”
