The software and computer services sector was in demand on Wednesday after results and updates from three of its constituents.FTSE 250 legacy software specialist Micro Focus soared after it revealed that it is trading ahead of expectations. The upbeat trading statement made a change from profit warnings, of which there have been two this year. Film software firm Zoo Digital rose after it reported an increase in full year operating profit and said it plans to raise £1.7m through a share placing. Gains for Micro Focus and Zoo Digital offset a large drop in the share price of internet video security company IndigoVision after it warned that sales and profits for the year ended 31 July will not meet its initial targets. The banks were among the worst performers, despite starting the day in positive territory. Lloyds, RBS and Barclays were among the top ten risers at the midday point, but slipped into the red after the opening bell in New York which saw the US benchmarks fall over 2% early on. RBS and Barclays were unwanted, while Lloyds was trading flat around 14.42pm.BCTop performing sectors so far todayPersonal Goods 21,353.81 +4.39%Industrial Metals & Mining 5,702.52 +2.99%Software & Computer Services 614.70 +1.65%Financial Services 4,965.44 +1.58%Real Estate Investment Trusts 1,978.51 +1.16%Bottom performing sectors so far todayIndustrial Transportation 2,203.36 -2.34%Banks 3,577.19 -2.31%Mobile Telecommunications 3,584.09 -1.91%Health Care Equipment & Services 3,056.72 -1.48%General Industrials 2,719.81 -1.39%
