Metro Performance Glass chief executive Nigel Rigby says it's still "early days" but it has been good to see the company's share price rise following its stock exchange debut today.
Shares in the country's largest value-added glass maker first traded at $1.75 - up from the initial public offering price of $1.70, giving the company a market capitalisation of $323.8 million.
Shares were up 4.1 per cent at $1.77 just before 1pm.
Recent initial public offerings - including those for technology firms ikeGPS and Serko and fruit marketer Scales Corporation - have fallen below their offer prices after trading commenced.
Rigby said it was important for investors that Metro's shares had a positive start on the market.
