German business confidence rose more than economists forecast to a 10-month high in February, adding to signs that Europe?s largest economy is gathering strength. The Ifo institute in Munich said its business climate index, based on a survey of 7,000 executives, climbed to 107.4 from 104.3 in January. That?s the biggest increase since July 2010 and the fourth straight monthly gain. Economists predicted an advance to 104.9, according to the median of 38 forecasts in a Bloomberg News survey. The Bundesbank said this week it expects the economy to return to growth in the current quarter after contracting 0.6% in the final three months of last year. Investor confidence jumped to the highest in almost three years in February and the benchmark DAX share index has gained 10% in the past three months.
