Stocks in the banking sector were among the highest risers on Wednesday as share prices rebounded following some heavy falls the day before.UK domestic bank Lloyds was towards the top of the pack on the FTSE 100 after bearing the brunt of the selling action on Tuesday. Shares in the part-nationalised lender dropped yesterday following the news that the government placed a 6% stake at a discount to the previous close as it formally began the process of disposing its near-39% stake after the state bailout in 2008.Barclays was trading without the right to buy shares in its £5.95bn rights issue - its fund raising first announced in July to help fill a £12.8bn capital shortfall.The shares were trading well below yesterday's closing price of 299p but higher than its theoretical ex-rights price (TERP) of 276.2p (meaning that they were making gains if the rights issue is taken into account).RBS, a heavy faller yesterday after receiving a ratings downgrade from UBS, was also rebounding today, along with emerging markets-focused lenders Standard Chartered and HSBC.Top performing sectors so far todayGeneral Industrials 4,205.58 +0.95%Technology Hardware & Equipment 1,138.48 +0.90%Banks 5,023.70 +0.82%Food & Drug Retailers 4,794.66 +0.69%Electronic & Electrical Equipment 4,065.70 +0.57%Bottom performing sectors so far todayAutomobiles & Parts 8,150.50 -1.61%Industrial Metals & Mining 1,586.62 -1.52%Real Estate Investment Trusts 2,378.82 -1.01%Travel & Leisure 6,651.19 -0.97%Financial Services 7,152.36 -0.91%BC
