Since the EU referendum, both gold and silver have soared, but silver has outshone its sibling precious metal. Silver is traded in lower volumes than gold, and usually rises or falls more than gold does, meaning the recent improvement in investor sentiment for both has helped silver more. Precious metals have done well because of economic uncertainty, as they are seen as safe havens, and as low interest rates have dimmed the appeal of cash. In the year to date, silver is up 42.2% while gold has risen 27.7%, in US dollar terms.
