THE stock market was stronger at noon on robust performances by financial companies, after Commonwealth Bank posted a better than expected first half cash profit.
At 12pm (AEDT_, the benchmark S&P/ASX200 index was up 13.2 points, or 0.27 per cent, at 4903.6, while the broader All Ordinaries index was up 11 points, or 0.22 per cent, at 4994.1 points.

Commonwealth Bank of Australia beat market forecasts with a $3.335 billion first half cash profit, but says credit demand remains subdued while funding costs are increasing. Its shares were up 95 cents, or 1.76 per cent, at $54.87.
EL&C Baillieu Stockbroking director Richard Morrow said the result had given the other major banks a boost.
"It's driven the entire bank sector higher, which is a continuation of the trend we've seen over the last few days of buying in bank shares," Mr Morrow said.
