BANGKOK, May 21 (Reuters) - Southeast Asian stock markets
mostly fell on Thursday, mirroring weakness around Asia after a
downbeat forecast for U.S. economic growth, with big caps like
DBS Group, Telekom Malaysia and PTT among the losers.

Singapore's Straits Times Index .FTSTI dropped 2.6
percent, ending four days of gains, while Thailand .SETI
dropped 2.3 percent after a four-day rally and Malaysia .KLSE
snapped a two-day rise to close down 0.7 percent.

Philippine stocks .PSI were flat but Vietnam .VNI
bucked the trend, rising for a fifth day by 0.5 percent.
Indonesia .JKSE was closed for market holiday.

Asian stocks fell after news the Federal Reserve had
lowered its forecasts for U.S. economic growth over the next
three years [nSP405491] and analysts said the weak global
outlook would continue to hold back regional stock markets.

"Global equities were already in a correction phase and the
Fed's downbeat forecast was just a trigger to sell. This weak
sentiment should continue for a while," said Warut
Siwasariyanon, head of research at Finansa Securities.

Singapore's biggest bank, DBS Group (DBSM.SI), lost 4.3
percent, Malaysia's Telekom Malaysia (TLMM.KL) fell 1 percent
and Thailand's biggest energy firm, PTT PTT.BK, lost 2.73
percent.

Other losers in Singapore included oil services company
Ezra Holdings (EZRA.SI), which lost 6.9 percent to S$1.21 after
it said it planned to raise $92 million through a placement of
78 million shares at S$1.185 each. [ID:nHKG370496]

Singapore Technologies Engineering (STEG.SI) lost 2.1
percent even though it said it expected to increase its order
book in 2009 as it was bidding for government projects in
China, Europe and the Middle East.

Thai energy stocks fell back after hitting a six-month high
on Wednesday, with PTT Exploration and Production PTTE.BK and
PTT Aromatics PTTAR.BK each falling more than 4 percent.
