Both Barrick and Newmont hope to continue to cash in on the combination of higher gold prices and lower costs. That is unless the gold rally is nearing an end, which is clearly what these billionaires believe. George Soros, for example, cut his stake in Barrick Gold by 94% amid the stock's epic second-quarter rally. That timing proved to be flawless given that Barrick's stock is down 17% since the quarter ended as a result of the sinking price of gold.
