Weaker energy and mining stocks have pulled the share market lower, despite gains by market heavyweights including Telstra and CSL.

The benchmark S&P ASX/200 index closed 0.09 per cent lower at 5,474.6, after earlier being as much as 0.6 per cent lower.

Energy and mining stocks gave up their recent gains after oil and other commodity prices fell, optionsXpress market analyst Ben Le Brun said.

“A strong US dollar overnight saw selling across the board for commodities and that sealed our fate,” he said.

Woodside Petroleum fell eight cents to $29.97, Oil Search slipped 15 cents to $7.50 and Santos was 10 cents weaker at $3.84.

Rio Tinto dropped 20 cents to $53.00, BHP Billiton shed 36 cents to $23.44 and Fortescue Metals was 15 cents weaker at $5.03.

Among the better performers was biotech firm CSL, which gained $1.06 to $106.54 after launching another $500 million buyback to improve returns for the shareholders.

Telstra gained five cents to $5.10 while three of the big four banks closed higher and National Australia Bank slipped 12 cents to $28.16.

Slater and Gordon fell 3.5 cents, or 8.3 per cent, to 38.5 cents on news aggrieved shareholders are filing a class action against the law firm for allegedly failing to meet its disclosure obligations amid its recent writedowns and annual loss.
