Golden Virginia-to-Gauloises Blondes maker Imperial Tobacco (IMT) puffs up 1.7% to £21.91 on reassurance it is on track to meet full-year forecasts with the help of at least £30 million of cost savings. Over the nine months to 30 June, volumes and revenues fall 7% and 3% respectively, a weaker-than-expected performance reflecting tough market conditions across the EU, notably in Spain, as well as further volume declines in Russia and the Ukraine. Nevertheless, chief executive officer Alison Cooper highlights good performances in Asia-Pacific, Africa and the Middle East and also announces the £21 billion cap is to launch an e-cigarette style product in 2014.

Gem Diamonds (GEMD) had already detailed its first-half performance in a trading update last month, so today's half-year results don't contain any surprises. Yet the market is troubled by the drop in earnings, despite this being old news - the shares falling 5% to 150.5p. Stockbroker Panmure Gordon says there's a better-than-expected performance on costs and a lower-than-forecast deprecation which translates into 'quite a significant difference at the bottom line'. It adds: 'We see little in today's results to alter our full year EBITDA (earnings before interest, tax, depreciation and amortisation) forecasts, but lower depreciation could see a slight uplift to full year net profit.' Gem is our top pick in the diamond sector.

IT refresh specialist Micro Focus (MCRO) has unveiled a 60p per share special dividend, just as Shares predicted in June.
