Deutsche Bank has chosen to reiterate its 'buy' rating on Lloyds Banking Group ahead of the lender's second-quarter results at the end of the month, saying that it its "top pick" in the UK banking sector."LBG provides attractive and cost-effective exposure to a strong UK economy, a profitable banking market, strong capital generation, and potential write-backs on weak credits taken in the downturn."Deutsche Bank said it expects Lloyds' underlying results "to show continued delivery by management in de-risking and streamlining the bank", when it releases its statement on July 31st.Analysts predict 20% year-on-year growth in underlying profit to £3.48bn in the second quarter. Meanwhile, the Basel III core tier-one capital ratio is forecast to improve to 10.7%, up from 9.1% the same time last year."We expect a long list of below-the-line items - including £500m in PPI conduct provisions - will see the bank report a small statutory loss for the second quarter but we do not expect this to materially detract from tangible net asset value growth or dividend prospects."Deutsche Bank's target price for Lloyds has been trimmed slightly from 90p to 87p, though this still implies 20% upside to current prices.The shares were down 0.9% at 72.53p by 11:17.BC
