Gold’s recent price advance had more to do with investor’s perception of dollar strength than a flight to safety after equities took a plunge, said Rick Rule, CEO of U.S. Global Investors. “My own belief is that popular perception of the continued purchasing power of the dollar and strength in the U.S. economy declined a little bit which caused U.S. equities to decline,” Rule told Kitco News on the sidelines of the Silver & Gold Summit in San Francisco.
