UK stocks wobbled Friday, and appeared headed toward a weekly loss, but Tesco shares rallied by the most in two years on deal and dividend news from the UK’s largest supermarket chain.

The FTSE 100 was edging down 0.1% at 7,155.72 after a flat open. Consumer services, tech and basic materials shares rose. But health care and financial shares were declining. The index on Thursday ended down by less than 0.1% after a choppy session.
