Singapore shares dipped amid cautious trading on Friday, slightly dampened as regional markets fell on profit-taking after a positive week.

The benchmark Straits Times Index shed 4.94 points, or 0.15 per cent, to 3,213.26.

Some 2.3 billion shares valued at $1 billion changed hands.

Among the losers was Keppel Corp, down 15 cents to $10.75 and Singapore Airlines, nine cents back at $10.17.

Regional markets were mostly lower, with Japan, Shanghai and South Korea ending in negative territory, but Hong Kong gaining ground.
