SE Asia Stocks-Most markets fall; Malaysia down for 5th session in six

* Indonesia up for fifth straight session

* Vietnam falls 2.9 pct to over 5-month low

By Nicole Pinto

May 28 (Reuters) - Most Southeast Asian stock markets fell

on Monday, with Malaysia declining for a fifth session

in six, while Indonesia extended gains on the back of

financial and infrastructure stocks.

"There are lots of pitfalls that could sideswipe the

markets," said Stephen Innes, head of trading APAC at Oanda,

referring to the U.S.-China trade issues, N.Korea-U.S. summit

and strong U.S. dollar.

U.S. oil futures hit six-week lows on expectations major

producers may ease output curbs, while Asian stocks and U.S.

share futures gained on signs the United States and North Korea

were still working towards holding a summit.

In Malaysia, trading services firms including IHH Healthcare

and Sime Darby were among the top losers.

IHH Healthcare fell as much as 4.8 percent and Sime Darby

plunged 9 percent on disappointing quarterly results.

Vietnam shares fell as much as 2.9 percent to a more

than five-month low. Vinhomes JSC declined 5.5 percent

and Vietnam Prosperity Joint Stock Commercial Bank fell

5 percent.

Indonesian shares climbed as much as 1.4 percent and

were headed for a fifth straight session of gains. Bank Mandiri

(Persero) Tbk PT rose 5 percent and Bank Central Asia

Tbk PT climbed 1.1 percent.

The central bank said on Friday that it would hold an

additional meeting of its board of governors on Wednesday to

discuss economic and monetary conditions.

"We suspect that the persistent selloff in the rupiah and

upward pressures on local government bond yields (despite the

recent 25bps rate hike) may prompt further action," DBS said in

a note.

"Further BI rate hikes may be needed, with the next one

possibly as early as this week."
