TAIWAN share prices finished 1.7 per cent higher yesterday as market sentiment improved, with all eight major categories of shares enjoying gains. 'More investors returned to the floor to pick up cheap shares in the hope of possible government-led incentives ahead of the December 2 parliamentary election,' Lin Long-shien, of United Securities, said. The Taiwan Stock Exchange weighted price index rallied 77.06 points to 4,663.81. Turnover increased with 628 million shares worth NT$18.1 billion (about HK$5.12 billion) changing hands, compared with 452 million shares worth NT$12.88 billion in the previous session. South Korean share prices dipped 2.35 points in yesterday's half-day trading, ending a week dominated by the country's slush fund scandal but cushioned by a late buying spree. The Composite Price index closed at 942.5, down 2.35 points from Friday's close and 3.85 points from last week's finish. Trading in the week was thin with an average of 15.5 million shares valued at 289.4 billion won (about HK$2.92 billion) changing hands daily. The first days of the week saw the index plunge below the 920-point mark on investors' jitters that the slush fund scandal involving an ex-president might deepen. But it rebounded mid-week on a feeling that prices had bottomed.
