London midday: Mining stocks celebrate QE3

- Footsie at six-month high after Fed decision- Mining stocks rocket on stimulus plans- Markets' upside momentum to remain in the weeks ahead, says analystLondon's stock market continued to extend gains on Friday morning after last night's announcement of more stimulus in the US, pushed the FTSE 100 to a six-month high; the index has not closed above 5,900 since March 26th. "European financial markets are jumping higher in response to fresh liquidity measures from the US Federal Reserve who essentially provided QE3 yesterday, pushing US markets to multi-year highs as a result," said market strategist Ishaq Siddiqi from ETX Capital.The Fed announced that, in order to bolster the economy and make sure that inflation stays close to its target, it would engage in a third round of quantitative easing (QE3) by buying more mortgage-backed securities at a pace of $40bn per month. It is also sticking with Operation Twist, the programme where it swaps short-dated securities for longer term securities. "When you add this with the ECB's bond buying plans announced last week, markets have been given another liquidity fix and we are now seeing fresh optimism which could continue into the end of the year. Moreover, promises by Chinese authorities to intervene with easing measures are likely to see the upside momentum remain in the weeks ahead." Siddiqi said.In other news, Japan has cut its assessment for its economy, with the Cabinet Officer saying that the "recovery appears to be pausing due to deceleration of the world economy". Meanwhile, Wolfgang Schaeuble, Germany's Finance Minister, has cautioned Spain against asking for further aid on top the €100bn for its financial sector: "I'm not in the camp that says 'take the money'," he said. "I don't share the view of those who say Spain is so much a focus of speculation in the financial markets that we should advise the Spaniards to do anything different from what they're doing...I'm one of those who says we should do everything possible to convince the markets that this speculation against Spain is without any basis in reality, he said.
