JAKARTA, April 22 — Most South-east Asian stock markets fell today amid regional weakness as disappointing earnings from US blue-chip companies and a fall in overnight oil prices curbed risk appetite.

Singapore led the fall, with the Straits Times Index trading 0.8 per cent lower, dragged down by offshore oil rig company Keppel Corp Ltd's shares which fell five per cent.

Suntec REIT fell 1.4 per cent after the company reported a marginal increase in its first-quarter profit in the previous session and OCBC Investment Research downgraded it to “sell,” saying valuation appeared stretched.

Thailand fell 0.3 from a near six-month closing high in the previous session on valuation concern.

Indonesia's Jakarta Composite Index was trading marginally lower, after touching its highest level in nine months earlier in the session.

“The JCI is expected to trade slightly lower today on profit-taking and negative regional sentiments,” said Dang Maulida, an analyst with KDB Daewoo Securities Indonesia.

“Meanwhile, domestic investors will be cautious on the upcoming first-quarter GDP release.”

Indonesia will release its Q1 GDP data in early May.

Bucking the trend, the Philippine market rose 0.1 per cent, while Vietnam advanced for a second day. — Reuters
