LONDON, Oct 14 (Reuters) - European shares surged to their highest closing level in more than a year on Wednesday as a surge in quarterly profits at JPMorgan <JPM.N> boosted sentiment, with banks and commodity stocks the biggest gainers.

"We are going into a very positive earnings season. So far we have seen this, with Intel <INTC.O> and JPMorgan. These are encouraging signs for the economy. It is not a time to desert equities" said David Buik, partner at BGC Partners in London.
Intel's quarterly outlook and results soared past expectations late Tuesday, fueling optimism over a tech sector recovery before the crucial holiday season. [

German engineering company Siemens <SIEGn.DE> advanced 5.2 percent with traders citing speculation that the company may hike its guidance. Siemens declined to comment.
