UK stocks started the day on the positive note as the BoE announced that it will maintain its bond-purchasing program. Moreover, positive construction PMI data both bolstered UK equities. However, after the ECB stated that fresh measures to preserve the Euro will be considered only in the coming weeks, UK stock index moved sharply lower. FTSE 100 Index tumbled 0.61% to trade at 5,689.33 at the time of writing. All industries in the index erased earlier gains. Basic materials and telecommunications were the weakest in the index. Anglo American and BHP Billiton declined 2.89% and 1.53%. Among telecommunications, BT Group and Vodafone plunged 2.06% and 0.74%. At the same time, health care sector was unchanged, being supported by Smith & Nephew. Smith & Nephew soared 2.35% after announcing a shift to a progressive dividend policy.
