Dec 29 (Reuters) - Most base metals fell on Wednesday as investors booked profits after recent rallies, but copper prices in London jumped to a one-month high on arbitrage trades.

Zinc and aluminium extended losses on the London Metals Exchange, which was closed on Monday and Tuesday for public holidays.

LME copper rose as much as 1.4% to $9,706 a tonne, its highest since Nov. 26, but the most-traded February copper contract on the Shanghai Futures Exchange fell 0.6% to 69,880 yuan ($10,968.11) a tonne, after scaling a one-month high on Tuesday.

FUNDAMENTALS
