Food company Goodman Fielder Ltd has reaffirmed its profit forecast despite a significant rise in its share price.

In a response to a query from the Australian Securities Exchange, Goodman said it was not aware of any information, which could explain the surge in its share price in recent trading.

The company's securities rose from a close of $1.27 on January 5 to $1.495 at the close of trading on January 9.

Goodman said it had no reason to believe that the company's first half profit results would vary from an outlook statement provided at its annual general meeting in November.

"We anticipate the variance in operating profit before abnormal items and income tax for the half year ended December 31 2008 compared to the previous corresponding period to be in line with the variance in net profit after tax," Goodman said in a statement.

First half profit still is expected to be about 15 per cent lower than the prior corresponding period.
