The Securities and Futures Commission has publicly reprimanded Yueng Chun-pong in respect of his registration as a dealer's representative under the Securities Ordinance. The commission yesterday said its investigation found that Mr Yeung had opened a securities trading account without also disclosing that he was an employee of another registered securities dealer. 'The . . . finding impugned Mr Yeung's efficiency, fairness and . . . his fitness to be a dealer's representative,' the commission said.
