London close: Footsie finishes week strongly, Man Group soars

- Footsie finishes up five points on the week- Stocks rise despite US GDP data, Spanish downgrade- Man Group jumped 14% after upgradeFollowing a steep sell-off on Monday, a four-day rise for blue-chip stocks saw the FTSE 100 finish slightly above levels seen last week with financials leading the way higher on Friday. Investors seemed to shrug off worse-than-expected economic growth in the US, a downgrade for Spain and some gloomy confidence data here in the UK with the benchmark finishing firmly in the blue.The rate of US real gross domestic product (GDP) growth was worse than expected in the first quarter of 2012. The US economy expanded at an annual rate of 2.2% in the first three months of the year compared with the fourth quarter of 2011, when GDP grew by 3%, according to a preliminary estimate from the Bureau of Economic Analysis (BEA). The figure falls short of the 2.5% expected by the market consensus. Meanwhile, Standard and Poor's downgraded Spain's credit rating from A to BBB+, saying that it now feels that the country's budget trajectory will likely deteriorate against a background of economic contraction and considers that its government will probably need to provide further support to the banking sector. In domestic news, the GfK UK consumer confidence index for the month of April has come in at -31 points, unchanged on the previous month. The consensus estimate was for a slight improvement to -30.
