4 executives banned from industry after computerized trading mistake

It took only three minutes. The operational error made by Everbright Securities two weeks ago has earned it a 523 million yuan ($85 million) fine from the nation's top securities regulator, for insider trading, release of misleading information, and muffed risk control.

That is the largest fine the regulator has ever given a securities brokerage in the history of the country's stock market.
