SINGAPORE - Singapore shares closed 0.81 percent lower Tuesday as sentiment turned cautious following Wall Street's tumble, dealers said.

The blue-chip Straits Times Index fell 22.12 points to 2,694.50. Volume totalled 1.52 billion shares worth 1.26 billion Singapore dollars (906 million US) while there were 117 rising issues, 408 losers and 821 flat.

"Caution rules with growing debate over the sustainability of the seven-month market rally due to rich valuations and lack of any substantial earnings upgrade potential," analysts from NetResearch Asia said.

CapitaLand was among the losers, closing 13 cents down at 4.30 after the property developer reported net profit fell 33 percent to 281.3 million dollars in the third quarter to September.

For other property developers, City Developments sank 22 cents to 10.24 and Keppel Land was off one cent at 2.83.

Singapore Airlines dropped 18 cents to 13.88 and Singapore Telecommunications eased one cent to 3.10.
