ST Group Food has prompted a query from the Singapore Exchange Regulation (SGX RegCo) following a 42.9% surge in its share price to 12 cents as at 12.28pm, from its opening price of 8.6 cents on July 30.

The market regulator at 11.56am asked if the company if it was aware of any information that might explain the unusual trading activity, or if it knew of any other possible explanation for the trading, including public circulation of information by rumours or reports.

SGX RegCo has also ordered ST Group Food to confirm that it remains in compliance of listing rules.
