SMALL timers joined major investors in an index-buying spree to drive Bangkok shares higher across the board, with the stock indicator closing above the 900 point-level for the first time in two months, brokers said. The SET index rose 15.59 points, 1.76 per cent, to close at 903.54 on heavy turnover of 9.18 billion baht. The index last closed above 900 points on April 23, when it finished at 901.26. ''There seem to be efforts to push the index up above 900 points,'' said broker Chusak Tanglertsampan, of Ekachart Finance and Securities. ''We believe the market is overheated.'' But most brokers said the market needed a correction and the index should move sideways for the rest of the week. Small banks led the gains on big volumes. TOKYO STOCKS ended higher after prices jumped up and down on index-linked trading shortly before the close. The Nikkei Average rose 325.87 points, 1.7 per cent, to 19,538.3. Brokers said earlier rebounds in the market had been triggered by short-covering to retrace selling linked to political uncertainty. ''The market rose today as sellers retreated in the recent sales-dominated market, but it wasn't that buyers were active,'' said Tsunehiko Wajima at Wako Securities. ''This is not enough to call it a turnaround.'' Brokers said public fund buying, which could not be depended on during recent falls, had succeeded in helping sentiment. That foreigners were not all that bearish on Japan stocks was also supportive. JAKARTA STOCKS closed mixed in fairly active trade dominated by buying from foreign investors. ''Buying outweighed selling interest among foreign players. But investors in general were still very cautious,'' one broker said. The official index closed at 356.18 against 355.64 last Friday. MANILA SHARES ended weaker as investors kept to the sidelines waiting for news to stir activity. ''Nothing was happening. Nobody seemed interested in either buying or selling,'' said Noel Reyes, vice-president at DMT Securities. He said the market was still consolidating. The Manila Composite Index closed at 1,568.96 points, down 4.95 points from Monday's 1,573.91. SYDNEY AUSTRALIAN shares ended lower in quiet trade as a feeling of apathy pervaded the market towards the end of the financial year. ''Essentially all that people are doing is dressing up their books for June 30,'' said Peter Stock of broker Austock. Dealers saw some profit taking in blue-chips, most of which were weaker. The All Ordinaries Index closed down 9.9 at 1,716.7. Dealers said the local market was quite resilient considering unstable markets in Tokyo and a weaker yen. TAIPEI TAIWAN stocks reversed slight early gains to close lower as turnover sank to its lowest level since January. The Weighted Index, which was up about 14 points in early trade, finished 11.88 down at 4,062.49. Turnover fell to NT$10.03 billion from Monday's $13.89 billion. A technical rebound lifted the index at the opening, but a lack of confidence in the bearish market soon pulled share prices down, according to brokers. ''There is nothing to talk about, nothing to hope for in the market. Most people just stay away from it,'' said Hong Chi-ming of Top Soon Portfolio Securities. SINGAPORE SHARES fell across the board on institutional selling of key index stocks but brokers said there had been no panic selling. The 30-share Straits Times Industrial Index fell 31.81 points, 1.75 per cent, to 1,787.68. Banks and shipyards led falls. ''The attitude is 'I've got profits so I lock in the profits now'. But at the 1,770 level, there would be some bargain-hunting,'' a foreign firm's sales director said. Other brokers also expect some buying at 1,750 to 1,770. Brokers said the market was likely to get into a summer lull before recouping for its traditional rally on the National Day on August 9. KUALA LUMPUR SHARE prices retreated after early gains to close broadly lower on profit-taking, with investors cautious about the market's direction after a major downward correction last week. The Kuala Lumpur Stock Exchange Composite Index ended at 724.96, up 10.29 points from Friday's close, after touching an early high of 737.18. The market was closed on Monday for a national holiday. WELLINGTON SHARES finished another quiet session slightly lower and dull trading is expected to continue. The NZSE-40 Capital Index closed down 2.51 at 1,646.28 with around NZ$18.8 million traded. SEOUL STOCKS finished active trade higher in a day marked by growing individual interest focused on large-capitalisation shares. Brokers expect the market to face see-saw battles between buyers and sellers today in increased trading volume. Cyclical buying prompted by bargain-hunting contributed to the rises in the shares of securities houses. The Composite Stock Index added 4.56 points to 770.62.
