London’s top-flight index finished on an all-time high for the second year in a row as surging mining stocks ensured a strong performance from the market.
The FTSE 100 closed up 64.89 points to a record 7,687.77, building on a stellar run thanks to a boost from London-listed commodity firms.
Rio Tinto and BHP Billiton lifted 84p to 3,942p and 23p to 1,464p respectively, as rising copper prices drove up demand.
Precious metal stocks were also in the ascendancy after the price of gold rose by 2.45 US dollars an ounce to 1,296.43 US dollars.
Mexican-based miner Fresnillo was among the biggest risers, climbing 39p to 1,429p, while Randgold Resources was up 150p to 7,410p.
Away from the top tier, the FTSE 250 Index also reached its highest level in history, closing 83.95 points higher at 20,726.26.
Richard Stone, chief executive of The Share Centre, said: “For the second year in a row the FTSE 100 has ended the year at an all-time high.
“Personal investors will have been relieved this year by a respite from the high volatility seen in the last couple of years.
“The level of volatility this year has been remarkably low by historical standards and this has perhaps meant fewer trading opportunities for those investors who trade more actively.
“Market commentators have expressed concerns about valuation levels for some time indicating a correction may be on the horizon.
“However, the market appears to be shrugging off any such concerns and continuing to go from strength to strength.”
