The record 523 million yuan ($85 million) fine may seem big, but Everbright Securities Co's troubles are far from over.

The company is facing claims estimated at 2.7 billion yuan by investors alleged to have been misled by the company's deliberate withholding of information about its 7.2 billion yuan trading mistake.

But lawyers said potential claimants may need more information from the China Securities Regulatory Commission investigation to pin Everbright down.
