Chief executive Bob Diamond announced that the lender is looking to increase its risk appetite despite its return on equity being set to fall from 7.2% last year to below 7% this year. Broker Seymour Pierce kept its 'hold' rating saying that it is uncertain about future growth in revenues.Vodafone is also under the weather, unaided by a target price reduction by Nomura.
