Zinc dropped the most in six weeks in London amid speculation that a rally to the highest level since 2011 lifted prices too far.
Prices climbed yesterday to the highest since Aug. 3, 2011, after posting this year’s biggest monthly advance in June. Orders to withdraw supplies from warehouses tracked by the London Metal Exchange fell a fifth session. From July 21 through yesterday, zinc’s relative-strength index stayed above 70, a level seen by some traders and analysts who study charts as a sign prices are poised to fall.
“We are seeing a technical reaction to recent gains, with some profit taking in a thin market,” Michael Turek, a senior director at Newedge USA LLC in New York, wrote in an e-mail. “There are some who are questioning the sustainability of higher prices.”
