London open: Markets cautious ahead of US jobs report

- Markets look ahead to US jobs report- Investors shrug off central bank action- Aviva jumps on Delta Lloyds disposalFollowing a subdued reaction to central bank policy decisions yesterday, European markets were lower in early trading on Friday as investors looked ahead to key employment data in the US due out later today.Stocks on Thursday seemed to shrug off the news that the Bank of England (BoE) ramped up its asset purchase programme and the European Central Bank (ECB) and the People's Bank of China (PBoC) both slashed their benchmark interest rates.Critics to the BoE move said that the £50bn increase in quantitative easing will only have a marginal effect on the real economy. ECB governing council member Erkki Liikanen said that the European rate cut should not be expected to save the day. Meanwhile, some say that the Chinese decision reflects policymakers' concerns about a 'hard-landing'."Risky assets failed to rally yesterday despite policy easing measures in China, the euro area and the UK. With the data calendar otherwise light today, the market's full attention therefore turns to the US employment report," said Barclays Capital analyst Khrishnamoorthy Sooben.The monthly jobs data from the Labor Department is expected to see over 100,000 non-farm payrolls added in June. The jobless rate is expected to remain at 8.2%.Aviva ups size of Delta Lloyd disposalHaving promised on Thursday that it would raise money from disposals, insurance giant Aviva moved quickly to act on that pledge by saying it will sell more of its stake in Delta Lloyd than originally intended, prompting a sharp rise in its share price early on.Food, ingredients and retail firm Associated British Foods rose after saying that it is to buy ethnic flour brand Elephant Atta from Premier Foods for £34m.Plumbing and heating group Wolseley was being pressured lower after Morgan Stanley downgraded its rating on the stock to 'equal weight'.
