Gold and silver are finishing the week on a high note, lifted by concerns over economic growth, a second wave of virus infections and simmering tensions between the U.S. and China. Gold headed back toward its peak in April, when prices hit the highest since 2012. Silver jumped to a two-month high. Prices are having a long-awaited breakout moment as market anxiety mounts, according to Rhona O’Connell, head of market analysis for EMEA and Asia at INTL FCStone.
