Singapore, Oct 7 (Reuters)- - Shares of Singapore diversified holding company Blumont Group Ltd and investment firm Asiasons Capital Ltd plunged on Monday after their trading suspensions were lifted.
Blumont shares tumbled as much as 87 percent with more than 87 million shares traded, 5.7 times the average full-day volume over the past 30 days. Asiasons shares dropped more than 90 percent with more than 64 million shares changing hands, 8.4 times the average volume.
The Singapore Exchange Ltd had imposed suspensions last Friday on the two stocks, as well as gold miner LionGold Corp Ltd, saying the market may not be fully informed of the companies' affairs after a steep drop in their share prices.
LionGold shares remained untraded after the company asked for the halt to continue, pending an announcement.
