Stocks to watch: SGX, penny stocks, AusGroup, Santak, Mary Chia

SINGAPORE Exchange (SGX): The bourse operator is suspending its minimum trading price (MTP) requirements for mainboard-listed companies as it considers a proposal to add a market capitalisation criterion to the current framework.

The moratorium will give more breathing space to 125 listed companies that are either already on the MTP watch-list or that were expected to be added to it in September.

AusGroup: The engineering, port and marine services company warned of a fourth-quarter net loss due to a "prolonged adverse business environment". The company also said it has decided to end its Sinagpore fabrication and manufacturing businesses.

Santak Holdings: The company warned of a significantly deeper loss for the year ended June 30 due to losses in the manufacturing and electronics trader's Wuxi, China operations and lower turnover. It expects to report its results by end-August.

Mary Chia Holdings: The beauty services company said on Wednesday it has received a notice of arbitration and a claim for S$4.81 million, excluding interest and costs, from its previous partner in a soured joint venture. Mary Chia said it has hired a legal adviser to contest the claim.
