Europe pares losses to close flat after weak US data

European equities trimmed losses on Thursday and closed flat, rebounding from heavy selling earlier in the session, as weak data from the U.S. helped to curb expectations of a rate rise from the U.S. Federal Reserve.

The pan-European Stoxx 600 index closed flat to higher but with some major European bourses finishing in negative territory. The benchmark provisionally closed 0.18 percent higher. It had recovered from earlier losses of over 1 percent with global sentiment dented by comments from Fed chair Janet Yellen and a sharp selloff in the fixed income markets.

Initial claims for state unemployment benefits rose 3,000 to a seasonally adjusted 265,000 for the week ended May 2, the Labor Department said on Thursday. Claims for the prior week were unrevised at 262,000, which was the lowest reading since April 2000.

Bond yields fell back after the figures and also helped market participants to look past comments from Yellen who said Wednesday that equity valuations were generally quite high.

Benchmark U.S. 10-year note yields traded as high as 2.27 percent before edging down to around 2.23 percent. Thirty-year bond yields also traded above 3 percent for the first time since December, before trading around 2.96 percent.

In Europe, German 10-year Bund yields nearly hit 0.8 percent after before trading around 0.64 percent.
