PROPERTY, construction and infrastructure development group Hopewell Holdings may seek a separate listing for its electric power generation operations in China and the Philippines. ''The company is investigating with its professional advisers the possibility of seeking a separate listing for its electric power generation interests and businesses,'' said Hopewell in a statement to the stock exchange. But it said no definitive decision had been submitted to the company's directors. Nor had any decision been reached as to the timing of any transaction or the financial terms on which it would be carried out. ''Whether or not any such transaction is consummated is dependent on a large number of factors and the directors believe it would be premature to speculate as to when or on what terms this might happen,'' said Hopewell. The company advised its shareholders and investors to exercise extreme caution in dealing in its shares. The share market yesterday reacted positively to the listing plan, sending the price of Hopewell shares up 10 cents to $5.10. The counter was one of the most heavily traded, with more than 27.65 million shares, worth $141.62 million, changing hands.
