Shares of iShares Silver Trust, a silver-backed trust that trades like a stock, rose 6.7% to $73.71 in after-hours trading on Tuesday, as spot silver — the cash price for immediate delivery — jumped 5.4% to $80.68 an ounce. “Precious metals traders see more risk on the horizon than stock and bond traders do at present,” said Jim Wyckoff, a senior analyst at Kitco Metals, citing the weekend U.S. raid in Venezuela and renewed safe-haven demand.
