London midday: Markets cautious ahead of US non-farm payrolls

- All eyes on US jobs data- Outcome could be a major factor in presidential elections- Admiral, Meggitt and RBS disappoint The FTSE 100 was little changed by Friday lunchtime, having trade within a narrow range for most of the morning session, with investors nervous ahead the pivotal employment data due out in the US in the coming hours.Concensus estimates are for a rise of 125,000 in non-farm payrolls in October, higher than the 114,000 gain the month before. Meanwhile, the jobless rate is expected to tick up to 7.9% from 7.8%.Market analyst Craig Erlam from Alpari said: "The US jobs report is always the most anticipated economic data release each month, but this month's carries with it even more importance. While the non-farm payrolls figure is the most important release among traders, as it is seen as a much more reliable indicator of employment, the unemployment figure is what tends to write the headlines."With the presidential elections remaining in a dead heat, the outcome in non-farm payrolls could be a major factor in whether Barack Obama secures another four years as US President, or whether Republican challenger Mitt Romney can secure his place as the premier of the world's largest economy. Election Day is Tuesday.Erlam said that a surprise move in the jobless rate back above 8% would be "devastating" for the Obama campaign: "To have such negative headlines regarding unemployment splashed all over the newspapers days before the people go to the polls is likely to swing the undecided voter in favour of Mitt Romney. And you can guarantee the Romney campaign would capitalise on the rise in unemployment."In other news, the UK economy is not expected to contract this year, but ill-timed fiscal consolidation in Europe and other external risks continue to pose risks, the National Institute of Economic and Social Research (NIESR) said in its latest quarterly forecasts. The British economy is now expected to grow by 0.1% in 2012, which marks a slight upwards revision on its previous forecasts. Next year however the external environment is no longer being forecast to make a contribution to aggregate demand, leading the NIESR to reduce its forecast for gross domestic product (GDP) downwards, to 1.1%, as net trade will not make any positive contribution. FTSE 100: Admiral, Meggit and RBS disappoint with Q3 resultsCar insurance firm Admiral dropped after seeing a 2% decrease in third-quarter turnover.

Technical analysts at Charles Stanley said: "A close above 168p would suggest that this line is giving way and would amount to a 'trading buy' signal."Oil giant Tullow was a high riser after JPMorgan Cazenove upgraded its stance on the shares to 'overweight'. In contrast, engineering giant Weir was under the weather after Jefferies cut its rating to 'hold' and supermarket group Morrisons fell after Morgan Stanley downgraded the stock to 'underweight'.
