The Securities & Futures Commission has reprimanded former CITIC Ka Wah Bank staff Chris Chan, fining him $25,000 for hiding his trading activities from his employer.

A Monetary Authority investigation found he conducted joint trading with a client in six stocks from October 2004 to January 2005 but had not informed the bank.

This conduct breached his employer's staff dealing policy and hindering the bank from monitoring his trading activities that might be prejudicial to clients and from ensuring legal compliance.
