UBS has raised its target price for UK lender Barclays by 21% but has maintained its neutral rating on the stock, saying it is "well-positioned but under-earning."The uplift in the target price, from 199p to 240p, reflects the improvement in tangible net asset value from the BlackRock revaluation and annual roll-forward."From a liquidity, capital and funding perspective, Barclays is well positioned. The proposed £1bn of cost reduction is also an incremental positive," the broker notes.However, UBS says that the firm is not generating sufficient revenues to reach the returns that are acceptable to both management and shareholders.Nomura has highlighted Legal & General (L&G) as its preference in the UK insurance sector, saying that it has higher cash yields than peers Aviva, Prudential and Standard Life."We estimate that L&G still has the highest cash yield of 10% in the sector, measured against our FY 2011 cash earnings forecasts," the broker said. It also forecasts an "attractive" 9% cash yield for Aviva, while Prudential and Standard Life have lower cash yields of 7% and 6%, respectively. "We also think that [L&G's] growth prospects are the strongest in the sector, as it is the best-positioned in its peer group to benefit from changes to product and distribution caused by the Retail Distribution Review," Nomura adds. The broker maintains its buy rating and 180p target price on the stock.As for Prudential, Nomura reiterates its reduce recommendation and 700p target price. Meanwhile, the broker has cut its target price for Aviva from 650p to 630p to reflect a reduction in forecast earnings. Nevertheless, a buy rating is kept. As for Standard Life, Nomura has raised its target from 250p to 255p after increasing its operating profit forecasts, but a reduce rating is kept.Prime Markets recommends to sell shares of Yell Group following the Yellow Pages publisher's third quarter update which sent shares tumbling nearly 14% in mid-morning trade."Due to the inexorable deterioration of it's core market and product, Prime Markets have long been sellers of Yell - we published sell notes in February, May and July 2011," notes head of dealing Richard Curr."Today really is groundhog day - our appraisal of the ailing directory giant could be a carbon copy of our July note as the figures, the debt pile and share price has barely changed since that time," he said.Prime Markets sets a price target of 4.8p.BC
