Two key investment banks raised their price targets for stock in Aviva PLC (LSE:AV.) – though neither seems particularly bullish on the outlook for the insurer's shares. Citi moved its valuation 5% to 441p following last week's interim results, while raising its operating profit forecasts by 5%, 7% and 9% respectively for this year, next year and the year after. Credit Suisse, meanwhile, maintained its 'neutral' recommendation while lifting its price target to 480p from 455p a share.
