Britain's benchmark FTSE 100 index closed at a fresh four-year high on Wednesday, powered by soaring miners tracking record copper prices, but catering firm Compass slumped 11.5 percent after warning on profit.
Miners Anglo American, Rio Tinto and Xstrata, put on nearly 4 percent each as copper hit a record high amid tight supply. Gains in the sector were given extra snap as the miners rallied from falls during the previous session, with Anglo particularly hard hit on Tuesday by cooling gold prices.
But the day's biggest gain was seen in the banking sector, with Asia-focused group Standard Chartered up 4.2 percent as buyers reacted to buoyant stock markets in Asia. Dealers added that vague bid talk was helping the rise, but Standard declined to comment.
The FTSE 100 index closed up 47.5 points or 0.9 percent, at the day's peak of 5,494.8, its highest reading since August 2001 and up 3.7 percent since the beginning of the month.
Andrew Bell, European Strategist at Carr Sheppards Crosthwaite, took a cautious view, even though markets remained bullish, as he anticipated consolidation after recent share market gains, and advocated a pause to assess the longer term impact of higher oil prices.
"The market's mood is that the economic outlook is probably going to continue to muddle through; that we've been through the worst that we're going to go through on the oil price, and equity markets are not that expensive," said Bell.
But share markets are likely to continue to look attractive compared to other asset classes as long as earnings grow.
"If earnings are continuing to grow, even if it's by a small amount, and the alternative is to stick money on deposit at 2 to 4 percent or in government bonds yielding 3 or 4 percent, the bar is set quite low," he added.
