MAS said Ngin and Yeo had the discretion to manage and advise on the execution of trades to achieve Wiluan's desired price for KS Energy shares. Ngin had traded KS Energy shares on 29 occasions between Oct 14, 2015 and Sep 13, 2016, inflating the traded price by at least 5 per cent, while Yeo had traded the shares on 7 occasions between Sep 22, 2015 and Oct 13, 2015, inflating the traded price by at least 5 per cent. Noting that trading representatives must play their part in helping to safeguard market integrity, Loo Siew Yee, assistant managing director (policy, payments and financial crime) of MAS, said: "The civil penalties and prohibition orders against the 2 individuals reflect MAS' firm resolve to stamp out such conduct." MAS noted that a civil penalty action is not a criminal action and does not attract criminal sanctions. CIMB Securities is currently known as CGS-CIMB Securities. It was renamed after China Galaxy Securities acquired a 50 per cent stake in the brokerage in 2018.
