Noble Group Ltd., a Hong Kong-based supplier of raw materials, gained after the company reiterated it will report a record quarterly profit and as falling commodity prices cut its working capital requirements.

Noble, which more than doubled second-quarter profit, was the index's biggest gainer. It rose 5 Singapore cents, or 11 percent, to 52 cents.

``Noble is on track to achieve a year of record earnings and could well surpass our $455.4 million net profit target,'' Lee Wen Ching, an analyst at OCBC Investment Research Pte in Singapore, said in a report published today. OCBC Investment maintained its ``buy'' rating on the stock and its S$2.53 fair value estimate.
