RAMPANT across-the-board advances pushed the Seoul stock market to a 31-month high in a liquidity-driven market yesterday after early institutional profit-taking failed to dent the bullish tone, brokers said. The Composite Stock Index added 11.69 points to close at 766.28, up from a previous high of 767.06 on October 25, 1990. ''Money flowing into the market greatly contributed to the bull run,'' said Kim Duck-sun of Hyundai Securities. Customer deposits totalled some 3.2 trillion won. Brokers expected the market to stay buoyant. They said individual and foreign investors were the major net buyers in the market. TAIPEI STOCKS closed lower across the board in sluggish trade as most buyers stayed out amid a lack of positive news, brokers said. The Weighted Index opened slightly lower and extended its losses in late trade, closing 51.23 points down at 4,317. Turnover shrank to NT$19.58 billion from $26 billion in Saturday's shortened session. Brokers said initial details of the Government's economic stimulus package, being reviewed by Premier Lien Chan yesterday, and Saturday's news that inflation had fallen sharply in May were insufficient to boost the sluggish market. MANILA SHARES rose on Friday's news of lower inflation, Philippine Long Distance Telephone Co's recovery in New York and expectations that Manila Electric Co would announce its 60 per cent dividend soon, brokers said. ''Those three developments managed to offset the resignation of Central Bank governor Jose Cuisia last week,'' Louie Bate of Baring Securities said. Inflation fell to 6.7 per cent in May from 7.9 per cent in April. The Manila Stock Exchange Index rose 16.88 points to 1,604.17. The Makati index rose 13.87 to 1,635.95. TOKYO STOCKS ended mixed, giving up early gains in late arbitrage-linked selling, brokers said. The market lacked themes, with people reluctant to move before the settlement of June futures and options, and the Bank of Japan's quarterly economic survey, both due on Friday. ''Although prices were higher earlier, the amount of buy orders was limited amid a lack of fresh incentives,'' said one broker at a foreign house. The 225-share Nikkei Average was down 38.05 points or 0.18 per cent at 20,844.19. The broader first section TOPIX index ended up 0.15 points at 1,671.85. SYDNEY THE Australian share market closed slightly lower with little direction from overseas markets and lacklustre gold stocks. The All Ordinaries Index closed down 2.5 points at 1,738.5. ''There is very little interest in the market and this was shown by the lack of volume,'' said one broker. National turnover was a slow 170.26 million shares worth A$186.43 million. ''It was totally flat across the board - not even gold shone today,'' said another. Brokers had hoped a recovery in gold might spur buying, but the gold marker fell 7.4 points to 1,858.9. BANGKOK THAI stocks closed lower as investors sold new stocks which had risen since their debuts last week, brokers said. The SET Index closed 4.94 points lower at 827.14 on active turnover of 4.32 billion baht. The index hit a high of 840.24 in the morning. ''Investors are [worried] by the approaching no-confidence debate on Wednesday and brokers recommend their clients to sell to take profits,'' said a broker at Phatra Thanakit. ''Selling might continue tomorrow morning.'' The opposition has initiated a debate on the performance of Prime Minister Chuan Leekpai's government, which starts on June 9. SINGAPORE SHARES closed weaker and most investors were cautious in taking new positions, brokers said. ''The market is undergoing a long overdue correction after an extended bull-run,'' said a senior broker at a securities house linked to a local bank. ''Investors are now cautious,'' he said. The 30-share Straits Times Industrial Index closed at 1,856.12, down 14.76 points from Friday's close. Brokers said the present correction was healthy. KUALA LUMPUR PRICES closed mixed as the market consolidated further, brokers said. Bargain-hunting activity fizzled out in the afternoon with the market further correcting itself after earlier gains, a broker said, adding that quality stocks remained under pressure. Falls in blue-chips dragged the Kuala Lumpur Stock Exchange Composite Index down 3.99 points to close at 728.16. Activity remained subdued due to stricter trading conditions imposed by brokers. JAKARTA SHARE prices ended mixed in moderate trade, with profit-taking dominating the market, brokers said. However, he added, selling pressure had not been great. At the present level, few investors were willing to part with selected quality stocks. The official Composite Index was down 0.32 points to 349.43.
