Tom.com has announced the formation of a joint venture with All Asia Financial to offer investors real-time stock analysis, as well as instant stock forecasts. Chief executive Carl Chang said the 50:50 joint venture, called AAStocks.com, would cater for the Greater China financial community and on-line services would be launched in Hong Kong and the mainland by the end of this month. They would also offer services to the Taiwan market in future, he said. Mr Chang said the portal had adopted technologies - used by All Asia Financial's sister company Tradetrek.com in the United States - to forecast the range of the price movement of any stock for five days. All Asia Financial and Tradetrek are the subsidiaries of US on-line financial and investment company Westport Financial. All Asia director Tang Yifan said Tradetrek.com had proved successful in providing such services to investors and it therefore planned to launch similar services in Greater China. Total investment in the joint venture would amount to HK$30 million, he said. Mr Tang said some services would charge subscriber fees with payment ranging from HK$200 to HK$400 per month. Other income would come from advertising. Shares in Tom.com, which posted a first-quarter loss of HK$45.37 million last month, fell as low as HK$4 yesterday, the lowest since listing on March 1. They closed at HK$4.40 yesterday. The company expects to break even in 2003.
