As the stock exchange trading hall closes for its makeover, the line-up of top officials will also take on a new look. Hong Kong Exchanges and Clearing (HKEx) chairman Charles Lee Yeh-kwong yesterday hosted the closing ceremony of the trading hall before its renovation begins. 'I hope the new hall will quickly become a new landmark representing the Hong Kong securities market when all its facilities are open for business in March or April next year,' he said. Hosting the opening of the new trading hall could be Mr Lee's last major ceremony for the exchange, before he steps down at April's annual general meeting after serving the maximum six-year term. HKEx director Marvin Cheung Kin-tung, former chairman of KPMG, is widely speculated to become Mr Lee's replacement, and Mr Lee is widely tipped by stockbrokers to be the first non-executive chairman of the Securities and Futures Commission. Responding to the rumours, Mr Lee told the South China Morning Post yesterday: 'Please stop the speculation and give me a break ... I am an old man and I want to enjoy a quiet retired life.' SFC chairman Andrew Sheng will leave the commission when his contract expires at the end of September. A bill to split Mr Sheng's role into that of a non-executive chairman and a chief executive is still being debated. Speculation has it that SFC chief operating officer Peter Au-Yang Cheong-yan, executive director Martin Wheatley and adviser to the chairman's office, Ian Johnston, are potential candidates for the chief's post. With the reshuffle at the top, the only certainty is that HKEx chief executive Paul Chow Man-yiu will still be there; his four-year contract began in May 2003. During the 20-year operation of the trading hall, the stock exchange has had seven chairmen and six chief executives. On its first day of operation on April 2, 1986, under chairman Ronald Li Fook-shiu and chief executive Jeffery Sun, turnover was $230 million and the market capitalisation totalled $245 billion. Yesterday, turnover reached $26 billion and market capitalisation amounted to $7 trillion.
