SINGAPORE - Singapore shares returned to positive territory on Tuesday following a positive lead on Wall Street, even as various other regional bourses ended in the red on weak Chinese data.

The local benchmark Straits Times Index gained 9.27 points, or 0.28 per cent, to 3,327.67.

Several Asian bourses closed lower after the release of a HSBC report showing that the performance of China's service sector fell to a record low in July.

Some 1.62 billion shares valued at $1.11 billion changed hands in Singapore.

There were 238 gainers, versus 179 losers, while 374 remained unchanged.

Polaris was the top traded counter here, rising 0.3 cents to 2.9 cents, with 160 million shares changing hands. The company is a distributor and retailer of mobile phones and consumer electronics.
