BANGKOK, Nov 23 (Reuters) - Thailand's benchmark stock index was down 1.37 percent at 685.69 at 0454 GMT on Monday,

having hit a two-week low of 684.82 in early trade.

Thailand's economy grew by a weaker-than-expected, seasonally

adjusted 1.3 percent in the third quarter, slowing slightly from

the second quarter but confirming the recovery from a brief

recession early this year.

The state planning agency said it expected the economy to

shrink 3.0 percent in 2009 and projected 2010 economic growth of

between 3.0 and 4.0 percent. and

Brokers said the GDP forecasts for this year and next were in

line with expectations, but worries about domestic politics and a

court case involving environmental health problems at the

country's top industrial estate would keep investors cautious.

'The lack of a buying catalyst remains the major problem,

amid the uncertainty over Map Ta Phut industrial estate and the

'red-shirt' rally planned for later this week,' KGI Securities

said in a research note to clients.

Stocks on the move included:

SHRIMP EXPORTERS UP

Shares in small-cap Asian Seafoods jumped 9.4

percent to 3.26 baht and Seafresh Industry rose 2.5

percent to 4.10 baht after newspapers reported the United States

was considering cutting anti-dumping duties on shrimps from

Thailand.

'Because there are no fresh factors boosting big caps,

investors are snapping up small-cap stocks ... such as Asian and

Seafresh, which are being pushed up by speculation about the

anti-dumping duties,' said Chakkrit Charoenmetachai, an analyst

with Far East Securities.

0453 GMT

SIAM COMMERCIAL BANK DOWN

The number three lender fell 2.8 percent to a two-week low of

79.50 baht, underperforming a 1.5 perent drop in the banking

subindex, as investors took profit after the stock rose

to a four-month high last Wednesday, brokers said.

0419 GMT

THORESEN THAI, PRECIOUS SHIPPING DOWN

Falls in the Baltic Dry Index, which measures the

cost of shipping key commodities, depressed shipping shares, led

by a 4.4 percent drop in Thoresen Thai Agencies,

Thailand's largest dry bulk carrier, to a near-three-week low of

27.

Precious Shipping eased 1.6 percent to a two-week

low of 18.60 baht, and Regional Container Lines fell

1.85 percent to 10.60 baht.

The Baltic index, which tracks rates to ship commodities,

ended a three-week rally on Friday, falling over 3 percent.
