Taiwan's share prices opened high and retained some of their gains by the end of trading Friday, with the weighted index, the market's key barometer, advancing 21.68 points, or 0.32 percent, to close at 6,769.86. Boosted by the Dow Jones index, which rose slightly overnight, the local bourse opened at the day's high of 6,807.46 and reached a low of 6,739.05 before bouncing back. A total of 3.97 billion shares changed hands on market turnover of NT$109.77 billion (US$3.33 billion).

For the week, Taiex gained 104.46 points, or 1.57 percent. One analyst said that with profit-taking on the rise, there was little room for the market to rise further in the coming days. But analysts at President Securities Co. disagreed, predicting that the Taiex would likely continue its rise to a level of 6,907, which was last seen on June 8, because of momentum in the market. They urged investors to pay more attention to the business opportunities in connection with agreements reached in the three-day economic, trade and cultural forum between Taiwan's ruling Kuomintang and China's Communist Party starting Friday.
