He said: "Such an easing leaves the door open for interest rates to remain on hold at least until early next year."Overnight, the HSBC China manufacturing PMI for July improved from 50.7 to 52, showing that growth had picked up faster than analysts' expectations (forecast: 51).Banks and housebuilders gain; Kingfisher and Easyjet slumpBanking stocks were leading the risers in London this morning with HSBC, Barclays and RBS all making gains. However, StanChart inched lower after having to swat away rumours that Chief Executive Peter Sands or Chairman Sir John Peace might be replaced in light of recent disappointing results. Housebuilders were also making gains, including Persimmon, Barratt Developments and Bovis Homes.After a strong start to the year, DIY retailer Kingfisher's like-for-like sales reversed into the red in the second quarter with trading "slower than anticipated", leading the stock to sink by 7% this morning.Budget airline Easyjet was also a heavy faller, dropping 4% despite confirming its full-year profit will rise at least 14%, in line with City forecasts. That came after it posted an 8.6% rise in third-quarter revenue, driven by higher passenger numbers, an improved load factor and the timing of Easter. In contrast, sector peer IAG saw shares jump after saying that its Iberia airline has reached an agreement with trade unions on collective redundancies for pilots and ground staff as part of its transformation plan. "This could lead to a reduction of up to 1,427 jobs at the airline."Consumer goods company Unilever erased earlier losses even though it reported a lower-than-expected increase in second-quarter sales, blaming a deterioration in emerging markets and flat developed markets.Reed Elsevier was a bright spark after reporting that underlying trends remain strong, enabling the business publishing and information company to drive a 5% improvement in profits in the first half.On the FTSE 250, Lancashire Holdings, Howden Joinery, De La Rue and Halma were all higher after updates and results, while Electrocomponents and CSR disappointed with earnings.FTSE 100 - RisersReed Elsevier (REL) 974.50p +3.78%HSBC Holdings (HSBA) 620.20p +2.12%Persimmon (PSN) 1,319.00p +1.93%International Consolidated Airlines Group SA (CDI) (IAG) 340.60p +1.58%British Sky Broadcasting Group (BSY) 928.00p +1.53%Barratt Developments (BDEV) 373.80p +1.27%Mondi (MNDI) 1,047.00p +1.26%Johnson Matthey (JMAT) 3,057.00p +1.16%Barclays (BARC) 213.30p +1.11%Royal Bank of Scotland Group (RBS) 326.70p +0.96%FTSE 100 - FallersKingfisher (KGF) 311.00p -7.44%easyJet (EZJ) 1,339.00p -4.56%Admiral Group (ADM) 1,506.00p -2.21%Petrofac Ltd.
