Soros says gold "isn't safe" Billionaire financier George Soros says that gold prices may continue to rise but warns that it's not a safe bet. Sept. 15 - In an exclusive interview with Chrystia Freeland, George Soros says that while gold may go higher it is the ''ultimate bubble.'' (Reuters) - Billionaire financier George Soros said on Wednesday that gold prices might continue to rise after hitting record highs this week, but he renewed a warning that gold is the "ultimate bubble." With economic and fiscal weakness crimping the developed world, Soros said all investments are at risk because "this is a period of great uncertainty, so nothing is very safe." Regarding gold, he said that after asset classes set new highs, there are almost always immediate reversals that disappoint investors. Soros' hedge fund, Soros Fund Management LLC, has been heavily invested in gold and gold-mining companies. "Gold is the only actual bull market currently. It just made a new high yesterday. In the present circumstances that may continue," he said at a Reuters Newsmaker event. "I called gold the ultimate bubble, which means it may go higher. But it's certainly not safe and it's not going to last forever," he said. Soros made the "ultimate bubble comment" in January at the World Economic Forum in Davos, Switzerland. He no longer is involved in management of his hedge fund.
