The Singapore Exchange (SGX) will end the designation of stocks in Asiasons Capital, Blumont Group and its related securities, and LionGold Corp and its related securities on Oct 21.

Trading in these stocks has since become more stable, SGX said in a statement.

"It is important for market forces to determine share prices in fair and orderly trading. The designation of the stocks and its ending are done in the interest of the investing public and the market."

SGX said it will continue to monitor closely the trading activities in the marketplace and advised the investing public to trade with care and caution.

Shares of Asiasons, Blumont and LionGold have taken a beating since they were designated on Oct 7, meaning investors cannot short sell the shares and must pay cash up front if they want to buy.

Their prices rebounded strongly on Friday before the announcement was made after the market closed. Blumont rose 16.7 per cent to 13.3 cents, Asiasons jumped 18.5 per cent to 12.8 cents while LionGold was up 6.3 per cent at 15.3 cents.
