Investec has downgraded its rating for banking group Barclays from 'buy' to 'add' but maintains that it is its preferred UK domestic lender. The target price for the stock has been lowered from 345p to 330p to reflect the impact of forthcoming dilution from the bank's so-called 'Leverage Plan'."There have been better times to take profits: ahead of a July 30th £6bn rights issue announcement for example. But for those investors who (like us) missed that opportunity, the stock is back within 1% of its July 29th close, and having been the sector's top performer over the past month, it may be time to lighten up," said analyst Ian Gordon.Jefferies has reiterated its 'buy' rating and 310p target price for supermarket group Morrisons, saying that the stock's valuation is 'undemanding' despite its recent strong run."As expected Morrisons reported a mixed H1 given the margin effort of reversing the Q4 12/13 trading pressures and the increasing revenue costs of growth initiatives. Still, undemanding valuation and a clear reduction in capex intensity from here onwards point to an improving outlook (admittedly partly reflected by the c20% share price rebound of the past three months)."Beer group SABMiller was in the red on Thursday morning after Nomura downgraded its rating for the Bulmers and Coors owner from 'neutral' to 'reduce'. The broker cut its target price for the stock by 15% from 3,300p to 2,800p.Nomura analyst Ian Shackleton said that he predicts a "more normalised" outlook for the global beer industry following the exceptional profit growth experienced since 2005. This, he said, is "unlikely to be matched". He also said that the "revolution" being seen in the craft-beef industry poses a threat for traditional beer operating models, especially in mature markets. BC
