LONDON (MarketWatch) -- European stock markets advanced on Tuesday, with solid earnings results from UBS and PostNL, and strong economic data lifting the investing mood.

The Stoxx Europe 600 index gained 0.1% to 337.30, partly recovering from a 0.3% loss on Monday.

Quarterly results were in the spotlight and helped push the pan-European benchmark higher. Shares of UBS AG (UBS) gained 1% after the Swiss bank reported first-quarter earnings ahead of expectations and said profit rose to 1.1 billion Swiss francs ($1.25 billion), compared with 988 million francs reported a year earlier.

Dutch mail and freight company PostNL NV rallied 11% after it said it swung to a profit in the first quarter and lifted its 2014 guidance.

On a more downbeat note, shares of Barclays PLC (BCS) dropped 3.8%, after the U.K. bank posted a 5% fall in adjusted first-quarter profit as fixed-income trading continued to slow.

The loss weighed on the U.K.'s FTSE 100 index , which dropped 0.2% to 6,810.14 on its first trading day of the week. U.K. markets were closed on Monday for a bank holiday.

Germany's DAX 30 index advanced 0.1% on Tuesday, with gains capped by a downbeat note from Credit Suisse. The investment bank moved to a benchmark position on German stocks from overweight, citing three reasons for the downgrade: Germany's growth premium relative to Europe is shrinking; competitiveness and funding-cost advantages are waning; and the country is exposed to Chinese risk, with triple export-exposure compared with Europe.

At the same time, Credit Suisse lifted French stocks to overweight from underweight in a bet on quantitative easing from the European Central Bank. The CAC 40 index was up 0.1% at 4,466.91. Shares of Alstom SA weighed in Paris, down 1.1%, after the French government urged General Electric Co. (GE) to alter the terms of its proposed $17 billion takeover of Alstom's energy assets.

Global equity strategist Andrew Garthwaite said France would benefit more than Germany from any ECB easing. The central bank meets on Thursday, but few economists expect the Governing Council to loosen monetary policy after inflation in April rose from March's four-year low.

In data news on Tuesday, the composite euro-zone purchasing managers index for April rose to 54, unchanged from the flash reading, signaling the fastest rate of economic growth in almost three years. At 10 a.m. London time (5 a.m. Eastern Time), euro-zone retail sales are due.
