DuluxGroup Limited has performed solidly on its own in its ASX (Australian Securities Exchange) debut on Monday.

DuluxGroup's shares, which have been demerged from Orica Limited, a chemicals and explosives firm, opened trade at $2.50 on Monday, while Orica started at $23.64, for a combined sum worth $26.14, which is 46 cents higher Orica's closing trade price of $25.68 last Friday, when the two companies were still regarded as one.

The shareholders of Orica got one share at DuluxGroup for every Orica share they controlled.

Trading at $2.50 per stock, DuluxGroup has its market capitlisation staked at around $905 million.

DuluxGroup was trading at $2.61 at 1325 AEST, with a sub of 33.6 million stocks traded, while Orica was down by $1.16 at the trading price of $24.52.

Peter Kirby, chairman of DuluxGroup said at the debut ceremony of the company that it would likely take around six months or so before the actual value to shareholders could be evaluated from the demerger.

"It's early days and it's only just starting," he said in the ceremony.

"Most of the research indicates that it takes six months to a year before you can really have a look at the combined price of the two entities and compare it back.

"But, we're delighted at the start this morning. The way it (the share price) just tracked straight up like that was superb, and I gather there's quite a lot of big buy orders.

"It's a good start, especially in a very soft market."

Patrick Houlihan, CEO of DuluxGroup, said the company would continue on developing its leading position in the Pacific region and create "niche market" key positions all over Asia.
