European stocks fell Tuesday, as some patchy corporate earnings encouraged investors to pull back from a market that has rallied sharply this year.

The Stoxx Europe 600 closed 1.5% lower. Health-care stocks on the index led declines, falling 2.5%, as Monday's steep decline in highflying U.S. biotechnology stocks weighed on the sector in Europe.

Elsewhere, investors looked to earnings.

Swiss engineering firm Geberit AG slipped after it said the surging Swiss franc hurt its first-quarter profit. Swedish industrial-tools maker Atlas Copco and Finnish paper maker UPM-Kymmene Oyj also declined after first-quarter results disappointed.

Oil major BP gave up early gains to finish lower after a decline in first quarter profit.

Stocks in Europe have enjoyed a strong run so far in 2015, with the Stoxx Europe 600 up 18.6% even after Tuesday's fall. The launch of the European Central Bank's massive bond-buying program, along with a tentative improvement in the region's economy, have fueled the move. But analysts say more convincing signs of earnings growth will be needed to drive markets higher.

"We have seen positive impulses like a weaker euro and ECB [stimulus measures] priced in and people are waiting for some positive earnings surprises. Overall we're not really seeing that yet," said Christian Stocker, an equity analyst at UniCredit.

Germany's DAX index fell 1.9% on Tuesday, France's CAC 40 lost 1.8%, while the U.K.'s FTSE 100 slipped 1.0%.

Tuesday's declines in Europe reversed the previous session's surge in stock markets, which came after a shake-up of Greece's team negotiating with creditors was seen by investors as increasing the chance of a deal on further financial aid for Athens.

Relief continued to spread in Greek markets Tuesday despite the pullback in broader European equities, with the Athex Composite index climbing 1.4%.

Greece's two-year bond yield fell more than two percentage points to 19.9%. A week ago, two-year yields touched nearly 30%. Yields fall as prices rise.

"The Greek government looks to be laying the ground for at least some form of political compromise," said analysts at Rabobank.

Still, Greek bonds remain at a level that indicates investors are pricing in a considerable risk of default.

In currency markets, the dollar fell against the euro and the British pound. The euro was up 0.9% at $1.0972 and sterling rose 0.7% to $1.5326.

The pound had earlier briefly dipped after the U.K. economy grew more slowly than expected in the first quarter. Slower growth is likely to encourage the Bank of England to hold off for longer before raising interest rates.

In commodities, Brent crude was 0.4% higher at $65.10 a barrel. Gold was up 0.8% at $1,212.90 a troy ounce.
