Equities have been sensitive to debt problems in Greece and other European nations in recent months on concerns the euro zone's fiscal problems will hamper a global economic recovery.
Although not unexpected, the downgrade weighed on a market that had rallied on earlier data showing euro-zone industrial output surged in April, achieving the biggest year-on-year percentage gain in almost two decades.
