In a dramatic move this morning, the Singapore Exchange (SGX) suspended the trading of three stocks, namely Blumont, Asiasons Capital and Liongold.
SGX said that the move is to safeguard the interests of the market as there could be circumstances that would result in the market not being fully informed.
SGX also queried the share trading activity of ISDN, ISR Capital and Innopac.
The stocks have run up significantly in the past few months and there has been speculation that syndicates have been playing these counters.
Market watchers said that this appears to be a co-ordinated action by the regulators against these traders.
