Industry Outlook: Gold Sector Momentum Continues
As to gold, you can read all about that in the World Gold Council’s mid-year outlook on gold. In January it broke US$5,500 an ounce, and by late June it was under US$4,000.
In fact, even after that pullback, gold remains one of the better-performing assets so far this year. Analysts see it holding a range for now, but a rate shift or fresh geopolitical stress could send it back toward US$4,500 or beyond.
