London open: Central bank hopes drive gains early on

- Leaders have 'no time to lose', says Juncker- Markets await ECB decision on Thursday- QE3 hopes drive gainsUK stocks rose in early trading on Monday on the back of hopes that the European Central Bank (ECB) will act this week to stem the Eurozone crisis.Eurogroup head Jean-Claude Juncker said in newspaper interviews this weekend that policy-makers have "no time to lose" to decide on measures to deal with escalated bond yields in peripheral Eurozone nations like Spain."The euro countries have reached a point where we have to use all means possible to show that we are determined to protect the stability of the euro zone... nobody should doubt the will of those involved, to prove our determination," Juncker said.This follows remarks from ECB President Mario Draghi on Thursday, who said that the ECB would do "whatever it takes to preserve the euro...and believe me, it will be big enough". Meanwhile, markets are also hoping that the Federal Reserve will implement more quantitative easing (QE) in the upcoming months, which has added to the increase in risk attitude. "There has been a lot of speculation that the Fed will announce QE3 in the US. Recent data has shown job creation falling, unemployment rising, manufacturing slowing and finally GDP drop to 1.5% in the second quarter," said analyst Craig Erlam from Alpari.FTSE 100: Financials provide a lift early onFinancial peers Aviva, Barclays, Schroders, RBS and Legal & General were among the best performers in the opening hour as risk appetite increased.
