A better-than-expected reading of German confidence pushed stock markets firmly into positive territory by Tuesday lunchtime.The ZEW Institute's index, which measures economic sentiment in the Eurozone's largest economy, surged to 48.2 in February, ahead of last month's reading of 31.5 surpassing forecasts of a reding of 35 . "This is just the latest in a long list of surveys out of the Eurozone which suggest 2013 is going to be the year when the region bottoms out and begins the move back towards recovery," market analyst Craig Erlam from Alpari said this morning. "It also all but confirms what the Bundesbank said yesterday that the German economy will not fall into recession in this quarter, despite contracting by 0.6% in the fourth quarter". However, he added the caveat that markets should not get "too carried away" with the data. "While these surveys are positive, we are yet to see any hard data to confirm that [the] worst is actually behind us. Once this starts to make its way out, I think we could see the start of the next phase of the equity rally, not to mention the euro's ascent back towards 1.40."FTSE 100: StanChart makes gains after upgradeEmerging markets lender Standard Chartered was performing well this morning after Morgan Stanley raised its rating for the stock from 'equal weight' to 'overweight'.
