STANLEY Gibbons - The stamps and collectibles firm is eyeing a boost from royal baby memorabilia after a 17 per cent increase in first-half revenues to £17.2 million. Higher costs cut profits by 10 per cent to £1.8m, but the interim dividend rose 9 per cent to 3p a share. Nikon - Weak demand for mirrorless cameras, designed to bridge the gap between compact models and high-end SLR devices, saw the Japanese group cut its annual profit forecast by almost a quarter to ¥65 billion (£433.2m). Enterprise Inns - Britain's largest pub landlord said net income during the 18 weeks to 3 August dipped 2.7 per cent, an improvement on the 4.2 per cent slide it reported for the first half of the year, when bad weather affected trading. Rio Tinto - Higher taxes and a fall in prices for commodities such as coal and iron ore led to an 18 per cent drop in first-half profits at the mining giant to $4.2bn (£2.7bn), but the dividend was hiked by 15 per cent to 83.5 cents a share. Paul E Schweder Miller & Co - The Financial Conduct Authority has fined two of the stockbroker's staff almost £116,000 for failing to prevent illegal price manipulation by Dubai-based private investor Rameshkumar Goenka. He was fined a record $9.6m by the Financial Services Authority in 2011 for market abuse.
