London open: Footsie rebounds from six-month low

- G8 summit fails to lift sentiment as euro worries persist- Chinese stimulus speculation does the rounds- Man Group surges early onDespite an underwhelming G8 summit at the weekend, London's blue chip index opening slightly higher on Monday morning after slumping to its lowest levels since mid-November 2011 on Friday.As expected, the Group of Eight (G8) world leaders this weekend spent a great deal of time focusing on efforts to promote global economic growth and particularly on the Eurozone sovereign debt crisis while showing their support for Greece remaining in the single currency."We agree on the importance of a strong and cohesive Eurozone for global stability and recovery, and we affirm our interest in Greece remaining in the Eurozone while respecting its commitments. We all have an interest in the success of specific measures to strengthen the resilience of the Eurozone and growth in Europe," the joint communiqué said."The news sounds great for the Eurozone but it's not the first time one of these meetings has generated positive news only for nothing to materialise so I don't expect to see much of a reaction in the markets," said analyst Craig Erlam from Alpari.Prime Minister David Cameron told reporters after the summit that Greece is voting whether to stay part of, or exit, the single currency - "the Eurozone has to put in place the most robust contingency plans for both eventualities," he said.Meanwhile, there were rumours that China could act to counter a slowdown after Premier Wen Jiabao called for "putting stabilising growth in a more important position". According to the Chinese Securities Journal, the world's second-largest economy could announce stimulus measures in the near term.FTSE 100: Man up after FRM acquisitionHedge fund manager Man Group jumped early on saying it is set to pay up to $142.8m for FRM Holdings, a global hedge fund research and investment specialist.
