European stock indexes ended their trading in down after the gains they recorded at the beginning of the session, in light of the continuing concerns of investors about the continued tightening of monetary policy by central banks, after economic data indicating that the US economy is recovering faster than expected. The European closed down 1%, after rising as much as 0.5% earlier in the session. The Financial Times 100 index in London fell by 0.4%, while technology shares fell by 2.5%.
