European stocks climbed on Wednesday after better-than-expected eurozone manufacturing data, a further sign that the region's economy is picking up.

The Stoxx Europe 600 closed 0.3% higher, bouncing back from early losses. The turnaround came after manufacturing-activity figures for the eurozone were revised higher, meaning that the sector grew more quickly in March than initially estimated.

The data are the latest signal that a modest recovery is taking hold in the euro area, which has left investors bullish on European stocks despite a huge first-quarter rally. The onset of European Central Bank quantitative easing, or QE, has provided a further tailwind for stocks, helping exporters and multinationals by weakening the euro.

Still, the rally has paused in recent days, with the Stoxx 600 falling 0.6% on Tuesday amid worries over Greece's negotiations with its creditors and a slide in oil prices that weighed down energy stocks.

"The retreat should not sour the mood of eurozone investors too much, given the scale of the gains over the last three months," said Ian Williams, economist and strategist at brokerage Peel Hunt.

Germany's DAX rose 0.3% on Wednesday, France's CAC 40 added 0.6% and the U.K.'s FTSE 100 advanced 0.5%.

Despite the gains in stock markets, government bonds--which typically suffer when investors look to riskier assets such as equities--continued to surge in the eurozone, with the 10-year German yield falling to a record low of 0.16%. Yields fall as prices rise.

The rally in government debt has been sparked by QE, with the central bank aiming to buy billions of dollars worth of bonds that are in short supply.

In currency markets, the euro rose 0.3% against the dollar to $1.0772 after some weaker-than-expected U.S. jobs data. The single currency had fallen sharply against the buck on Tuesday, but still remains well above last month's 12-year low of under $1.05.

In commodities markets, oil bounced back from Tuesday's slide as investors continued to eye nuclear talks between Iran and six world powers which could raise the chance of increased Iranian oil exports.

Brent crude was up 2.9% at $56.69 a barrel. Gold was 1.5% higher at $1,200.70 an ounce.
