London open: Markets nervous ahead of US jobs data

Markets declined on Friday morning, despite relative strength in the mining sector, as traders refrained from building positions ahead of the key risk event of the day - the US employment report.The market reaction to the non-farm payrolls figure will be interesting to see, given the somewhat disappointing labour-market data in recent days, after both the ADP employment report and jobless claims figures missed forecasts.Consensus estimates are for a 199,000 increase in non-farm payrolls in March, well below the 236,000 surge in February. Meanwhile, the jobless rate is expected to stay at 7.7% following an unexpected drop the month before.If the official figure today misses forecasts, markets could react positively given increased hopes that the Federal Reserve will maintain the rate of its quantitative easing (QE) programme."Traders are of the view that if we see a figure that falls short of expectations, it would go some way to support the idea that the Fed will not halt or end QE anytime soon as the unemployment rate remains stubbornly high," explained Market Strategist Ishaq Siddiqi.Alternatively, if we see another strong beat today - as was the case last month - it could throw weight behind the argument by many US policymakers that stimulus measures will need to be scaled back.easyJet flying lower after trading updateBudget airline easyJet sunk despite meeting forecasts with its first-half guidance and reporting growth in passenger numbers in March.
