0806 GMT - Rolls-Royce is now on a steady footing, RBC Capital Markets' Mark Fielding says. The British aerospace and engineering group lifted its profit guidance for the year after booking a strong first half, with underlying revenue and operating margins coming in ahead of expectations. Rolls-Royce management has turned performance around over the last few years, Fielding says, noting the impressive margins across the company's business divisions. Shares trade 3.9% higher at 1,433 pence in morning trading in London.
