Palladium is heading for the biggest weekly decline in more than three years as investors’ focus turned to demand amid concerns over slowing global growth, with the slump following repeated warnings that the metal’s recent surge to record highs had propelled it into bubble territory. The metal used in auto catalysts to curb emissions sank 12% this week after hitting an all-time high on supply woes on March 21. The massive rally, which saw prices almost double since August, spurred predictions a reversal was inevitable, and hedge funds had cut bullish bets for a fourth week.
