Earlier, there were market rumors that the sudden morning surge in share prices could have been a signal that the securities watchdog may announce a new policy in reopening "T+0", a trading method that has been suspended since 1995 to prevent huge fluctuations.

Jiang, the commission's spokesman, denied this at a news conference, while saying that this system is being studied but is unlikely to be reintroduced in the near term.

Wu Nan, a manager at a quantitative investment fund in Beijing, said another possibility was that the trader made an order, thinking it was on a virtual trading system, when it was on a computer connected to the real exchange market.

"On the trading desk we usually have two computers together. One is for real transactions and the other one is for virtual trade," Wu said.

"But in general there is a firewall between the two computers, and any big purchasing order should be approved by the compliance department.

"The rumors said it was about 7 billion yuan, so this is unbelievable," he added.

Xiao Gang, head of the China Securities Regulatory Commission, wrote in Qiushi magazine this month that much of the agency's efforts in enforcement have been frustrated by the complex web of vested interests.

These are sometimes linked to government officials and senior executives of publicly traded companies, stock-broking firms and financial institutions. Investigators with the commission are faced with a host of problems ranging from detection to evidence-gathering to conviction, Xiao wrote.

China Everbright Group and its Hong Kong-listed unit, China Everbright Ltd, hold 67 percent of Shanghai-based Everbright Securities. The group has businesses ranging from banking, securities, insurance, futures and asset management to hotels, tourism and property development.
