LONDON, Jan 30 (Reuters) - Nickel led base metals lower on Tuesday as the dollar fell and investors booked profits from a rally that saw the stainless steel ingredient hit a high last seen more than two years ago.
Benchmark LME nickel eased 1 percent to $13,670 ounces by 1210 GMT. The metal, which is also used in electric vehicle batteries, touched $14,040 per tonne on Monday, its highest since May 2015.
"It's most likely profit-taking. Base metals are down across the board and there has not been much reason for nickel to have been up in the first place," said Societe Generale metals specialist Robin Bhar.
He said the move lower by nickel was likely an unwinding of the speculative buying that pushed the metal higher last week. But he added that rising demand and falling stocks meant fundamentals for the metal were gradually improving.
Nickel jumped 7.3 percent last week, making it the best performing base metal.
INVENTORIES: On-warrant LME inventories of nickel <MNISTX-TOTAL>, those not earmarked for delivery, fell to their lowest level in 2018 at 250,920 tonnes.
POSITIONS: Funds have raised their bets on prices rising, with LME net long nickel positions rising to 47,708 lots on Jan. 26, the highest since Jan. 2017. <LME-NI-MNET>
