LONDON, July 23 (Reuters) - European shares ended at their highest in more than a week on Friday, led higher by miners, as strong corporate results and encouraging economic data improved market sentiment.
Investors traded cautiously throughout the session ahead of results of stress tests for 91 European banks, which came in after the close of the European market.
Organisers of the tests said seven banks would not be strong enough to withstand another recession and would face a total capital shortfall of 3.5 billion euros ($4.5 billion). [
]"This is not surprising that most of them have passed -- the results are in line with expectations," said Philippe Gijsels, head of research at BNP Paribas Fortis Global Markets.
"The market will find good news and bad news in this and the market action on Monday and Tuesday will be very important for the rest of the month. But we will continue to be volatile."
The pan-European FTSEurofirst 300 <
> index of top shares closed 0.5 percent higher at 1,044.31 points, the highest close since July 14.Banking stocks were higher, with the STOXX Europe 600 banking index <.SX7P> up 0.2 percent. Banco Santander <SAN.MC>, Royal Bank of Scotland <RBS.L> and Commerzbank <CBKG.DE> were up 1.3 to 2 percent.
Stress test results showed five of Spain's smaller regional lenders, known as cajas, failed the test. Their recapitalisation will likely speed a restructuring of the troubled sector.
Banks in Germany and Greece were also seen as weak spots and in need of restructuring, but state-owned Hypo Real Estate was the only German lender to flunk and state-controlled ATEbank <AGBr.AT> the only Greek bank to fail.
