Two Cheung Kong (Holdings) and Hutchison Whampoa group affiliates, i21 and Aastocks.com, have formed an alliance providing retail investors with online analysis tools which could help them forecast stock price movements five days in advance. Under the partnership, Aastocks, 50 per cent-owned by Tom.com - which is controlled by Cheung Kong and its associate Hutchison - would provide its artificial intelligence-based analysis tools to i21. I21, a joint venture of iBusiness which is also controlled by the two blue chips, provides an online stock-trading platform to brokers. Eric Lau, Aastocks director of business development, said the company's analysis tools could predict particular stocks' five-day price movements as well as their six-month targets by tracing past trading behaviour. The tools also made real-time commentaries and recommendations on stocks' potential performances. 'Such technical analysis used to be applied by Wall Street's institutional players,' Mr Lau said. However, the partnership would now allow retail clients to have access to such services through those brokers who used i21's platform, i21 chief executive Rickie Fung said. Because the services involved investment recommendations, Aastocks had already obtained an investment adviser licence from the Securities and Futures Commission, Mr Lau said. According to an SFC circular published last July, providing analysis tools which generates recommendations on specific stocks or funds on a Web site could constitute an investment activity. Mr Fung said i21 planned to charge brokers a monthly fee of several hundred dollars per client for use of the analysis services. 'But exactly how much retail investors should pay will depend on brokers' own pricing schemes,' Mr Fung added. About 10 brokers had already signed up to use i21's online trading platform, he said. The company has also reached an agreement with Cyberbrokers, a broker alliance which has about 30 members, giving i21 priority to provide trading technologies to its members. I21, in return, would give the members a discount on the use of its trading platform, Mr Fung said. The company usually charges brokers a monthly fee of several thousand dollars and also receives a fee of about HK$10 per trade.
