European stocks remained weaker and the euro wilted against the dollar Thursday as European and Asian data compounded worries about global growth, while yields on the debt of fiscally strained euro-zone nations were stable after a Spanish government bond sale exceeded targets. Spain raised 4.8 billion euros ($6.22 billion) at an auction of debt maturing in three and 10 years, compared with a goal of EUR3.5 billion to EUR4.5 billion. The average yield on the 10-year bond fell to 5.666% from 6.647% at the previous sale of the maturity Aug. 2.
