However, stocks extended gains in the afternoon after ECB President Mario Draghi struck a dovish tone in a press conference following the bank's decision, saying that the Governing Council had even discussed a rate cut at this month's meeting but decided against it. Draghi did however raise his expectations for Eurozone growth for this year.A barrage of US economic data came in better than expected this afternoon, supporting the call for the Federal Reserve to begin tapering asset purchases at its next meeting later this month - jobless claims fell more than forecasts, factory orders declined less than expected and the ISM non-manufacturing index smashed estimates.However, given that the Fed has explicitly said that the labour market is a key factor in its decision, analysts will be watching the August employment report - due out on Friday afternoon - very carefully.

The Swiss bank highlighted alleviated concerns about pipeline after the company added more rooms in the first half and also pointed to improving growth in China and continued strength in the US.Decent August traffic statistics from airline peers easyJet and IAG over the last 24 hours have helped both stocks rebound today after falling heavily yesterday on the back of a profit warning from Ryanair, Europe's largest low-cost carrier.Banks were also performing well with Lloyds, Standard Chartered, HSBC, RBS and Barclays all registering decent gains. Lloyds was being helped higher by reports that the Treasury could delay the sale of its 39% stake until later this year because of ongoing tensions in the Middle East and the Fed's taper plan.Meanwhile, food groups Tate & Lyle and AB Foods were lower after Credit Suisse highlighted concerns about sugar prices falling sooner and more steeply than expected.Pharmaceuticals group GlaxoSmithKline was also in the red after announcing a setback on its potential new skin-cancer treatment during clinical trials.FTSE 100 - RisersPersimmon (PSN) 1,152.00p +3.69%Marks & Spencer Group (MKS) 494.90p +3.38%ITV (ITV) 174.60p +3.07%Lloyds Banking Group (LLOY) 74.77p +2.95%International Consolidated Airlines Group SA (CDI) (IAG) 299.40p +2.89%Kingfisher (KGF) 405.80p +2.86%GKN (GKN) 346.60p +2.70%Standard Chartered (STAN) 1,472.50p +2.58%Wolseley (WOS) 3,383.00p +2.52%Rolls-Royce Holdings (RR.) 1,147.00p +2.50%FTSE 100 - FallersTate & Lyle (TATE) 799.50p -1.60%Croda International (CRDA) 2,607.00p -1.25%GlaxoSmithKline (GSK) 1,652.50p -0.81%British Sky Broadcasting Group (BSY) 851.50p -0.76%Associated British Foods (ABF) 1,829.00p -0.65%G4S (GFS) 254.40p -0.62%Antofagasta (ANTO) 881.00p -0.56%Bunzl (BNZL) 1,365.00p -0.44%Aggreko (AGK) 1,599.00p -0.37%Admiral Group (ADM) 1,260.00p -0.32%FTSE 250 - RisersICAP (IAP) 400.00p +6.70%Dixons Retail (DXNS) 46.88p +5.92%Supergroup (SGP) 1,227.00p +5.87%Imagination Technologies Group (IMG) 279.30p +5.68%Tullett Prebon (TLPR) 382.40p +5.29%Home Retail Group (HOME) 152.50p +5.03%Halfords Group (HFD) 381.00p +4.01%Rentokil Initial (RTO) 107.50p +3.97%Hochschild Mining (HOC) 277.90p +3.89%Galliford Try (GFRD) 1,015.00p +3.73%FTSE 250 - FallersBumi (BUMI) 213.40p -2.87%Countrywide (CWD) 550.00p -2.65%BH Macro Ltd.
