LONDON, Aug 2 (Reuters) - European shares hit a three-month closing high on Monday, to finish above a key resistance level, boosted by strong results from HSBC <HSBA.L> and BNP Paribas <BNPP.PA> and better than expected U.S. manufacturing data.
The STOXX Europe 600 banking sector index <.SX7P> surged 3.9 percent, snapping two days of losses. HSBC and BNP Paribas both jumped 5.3 percent, after the banks trumped earnings forecasts as bad debts fell sharply.
According to Thomson Reuters StarMine data, 12-month forecast earnings growth for the banking sector is one of the highest, at 81.4 percent, compared with the STOXX 600 average of 25.9 percent.
The pan-European FTSEurofirst 300 <
> index closed up 2.6 percent at 1,070.93 points. The index has slipped in the past three sessions but ended 5 percent higher in July to record its first monthly gain since March."Positive results in the banking sector and U.S. ISM figures have pushed up the market," said Philippe Gijsels, head of research at BNP Paribas Fortis Global Markets in Brussels.
"The Euro STOXX 50 index has broken its 200-day moving average, which is very important as investors put short-stops on this and once it is hit they buy back their positions, which is helping to boost the market."
The Euro STOXX 50 index <
>, the euro zone's blue-chip index, closed 2.9 percent higher at 2,822.17 points, above a key technical resistance of around 2,800 points.Investor sentiment was also buoyed after the U.S. ISM manufacturing sector grew in July for the 12th straight month at a rate that was slightly better than expected. [
]Greek bank shares <.FTATBNK> rose 7.2 percent, helped by continuing merger talk. Alpha Bank <ACBr.AT>, Greece's third-largest lender, gained 8.1 percent.
On Sunday, Alpha Bank's chairman, Yannis Costopoulos, told a Greek newspaper the lender would consider teaming up with a foreign bank if it is large and strong enough. [

INTERTEK GAINS

]"The earnings season is doing the trick. The results are better than expected," said Heino Ruland, a strategist at Ruland Research in Frankfurt.
Miners were also higher as industrial metal prices hit multi-month highs, after investors grew more optimistic about the economic outlook.
Anglo American <AAL.L>, Antofagasta <ANTO.L>, BHP Billiton <BLT.L>, Eurasian Natural Resources Corporation <ENRC.L>, Rio Tinto <RIO.L> and Xstrata <XTA.L> rose 3.7 to 5.9 percent.
