However, mining and commodities group Glencore outperformed to rise 0.5 percent after the company announced a share buyback programme of up to $1 billion (R10.7 billion) as it posted a forecast-beating 8 percent rise in first-half core profit. Banking group Standard Chartered also outperformed with a 0.7 percent advance. Standard Chartered said late on Tuesday, after European stock markets had closed, that it would pay a $300 million penalty and suspend or exit some important businesses after failing to weed out risky transactions that could be linked to money laundering. Traders said the gains in the bank's share price reflected an element of relief that the penalty was now out of the way, after media reports about it had circulated beforehand. Standard Chartered's underlying business remained in good shape, they said. "They've got more than enough capital to cover the fine," said Beaufort Securities sales trader Basil Petrides.
