THANKS mainly to rises in the Jardine group and ComfortDelgro, the Straits Times Index on Tuesday recorded a 16.22 points rise to 3,434.24, regaining all of the 13 points it lost on Monday.

Turnover, however, was a mediocre 974 million units worth S$1.1 billion and excluding warrants the advance-decline score was decidedly mixed 207-204, indicating limited investor participation.

The index's main contributor was Jardine Matheson, whose US$1.33 or 2 per cent jump to US$66.23 added five points to the STI. Transport firm ComfortDelGro came next, its sudden S$0.15 or 5 per cent rise to S$3.09 with 13.4 million traded adding a further 3.5 points.
