China Securities Regulatory Commission imposed a fine worth 10.2 million yuan against Northeast Securities' (SHE:000686) unit, Bohai Futures, for trade manipulation, according to a Shenzhen Stock Exchange filing on Saturday.
A probe found that Bohai Futures was involved in the manipulation of a coke and coking coal trade contract, which affected the futures trading volume and prices.
The regulator also fined some of the people-in-charge of the manipulation between 100,000 yuan and 200,000 yuan, the Chinese financial services provider said.
Northeast's shares closed 1% lower.
