European stocks advanced for a fifth day, their longest rally this year, as data showed the U.K. avoided a triple-dip recession and as companies including British American Tobacco Plc (BATS) reported results.

The Stoxx Europe 600 Index added 0.8 percent to 296.88 at the close, its highest price since April 2. The measure has rallied 4.1 percent so far this week as company earnings beat forecasts and investors speculated the European Central Bank will cut interest rates.
