London has got off to a quiet start overall but there is plenty of corporate news for traders to digest and stocks are moving in both directions.BP is the laggard of the FTSE 100. The rising price of oil and gas boosted its profits in the second quarter, though the benefits were partially offset by lower production as a result of the oil spill in the Gulf of Mexico. The oil giant saw second quarter profits of £3.2bn, against a loss of £10.3bn for the same period last year. Benefits of the soaring oil price were tempered by BP's ignominious exit from the Gulf of Mexico following the oil rig disaster and subsequent leak there.In contrast, BG Group is in demand. The oil and gas leviathan saw second quarter earnings per share jump 27% to 33.1 cents from 26.1 cents a year earlier. The interim dividend has been hiked by 10% to 10.8 cents. Today's biggest percentage movers are to be found in the FTSE 250 though. Investors have no appetite for pork products supplier Cranswick, which expects full-year results to fall short of expectations as it continues to face high input costs and a weak consumer environment. The company, which supplies sausages and bacon for the Sainsbury's 'Taste the Difference' range, says it is in discussions with customers as it seeks to mitigate the effects of higher raw material costs. But interim results from set top box maker Pace have cheered investors.In other sectors, chip designer ARM beat high expectations with its second quarter figures. The market had been expecting normalised EPS of 2.43p, but ARM delivered EPS of 2.98p, up 27% from 2.34p in the second quarter of 2010. Normalised profit before tax climbed 25% to £54.2m from £43.5m the year before. Revenue in dollar terms grew 27% to $190.2m from $150.3m a year earlier, but in sterling terms the rise was only 18%, to £117.8m from £100m. Daily Mail publisher DMGT continues to cut jobs amid persistent weak advertising revenues in its newspaper business. While underlying revenues were up by 2% from the same period a year ago to £495m in the third quarter, this was due to strength in its specialist business publications division, where underlying revenues rose by 8% to £229m. Also in media, Specialist business publisher and trade events group Informa posted flat first half pre-tax profit and said, despite economic headwinds, overall trading remains in line with company expectations for the full year. Pre-tax profit was little changed at £66.5m for the six months ended 30 June 2011 compared to £66.4m before. Revenue increased to £634.8m from £624m previously.
