May 1 (Bloomberg) -- Nickel declined as a technical indicator signaled to some investors that last month’s gains to the highest level since February 2013 were excessive.
The contract for delivery in three months on the London Metal Exchange retreated 0.7 percent to $18,200 a metric ton at 3:46 p.m. in Tokyo. The metal rose 15 percent last month, the biggest such gain since September 2012. Prices advanced for a fifth straight month, the longest rally since August 2009.
Nickel’s 14-day relative strength index has been above 70 since April 9, a level suggesting an impending drop to some analysts who study technical charts. Futures climbed 31 percent this year, the most among the six main metals traded on the LME, as Indonesia, the biggest nickel miner, banned ore exports in January. The price touched $18,715 on April 28.
“It’s a technical correction in thin trade as nickel has been overbought,” said Chae Un Soo, a metals trader at Korea Exchange Bank Futures Co. in Seoul. Other metals remained subdued on concern that demand will slow after China’s official factory output data missed estimates and the Federal Reserve reduced monetary stimulus, he said.

A similar gauge from HSBC Holdings Plc and Markit Economics Ltd. released last week rose to 48.3, from 48, indicating China’s economy continued to stall in April.
