KRX has asked DSK to discipline its employees implicated to the incidence, for violating the market regulations, specifically, for negatively impacting on the stock prices by accepting the orders undermining the fair trading system and selling a large quantity of securities for its own account and playing a significant role in a specific investor gaining a huge unfair profit, thus damaging the credibility of KRX.

In addition, KRX has issued a warning notice to the Hana Daetoo Securities for violating the market rules related to member margin for trading derivatives products.

According to KRX, the DSK not only accepted the entrustment of a large bid order of put options and a large ask order of stocks, but also played a significant role in a specific investor gaining a colossal amount of unfair profit.

KRX also accused the DSK of manipulating the prices of concerned stocks and KOSPI.

Additionally, the DSK violated the reporting requirements of members that are established to prevent unfair trading, said KRX.
