"It's a pleasant surprise, but perhaps just a short-term move," says one. Cites Tuesday's speculation on a possible M&A as well as less than worst case impact from a pending storm in the Gulf of Mexico as sources of positive sentiment, but relatively old news. Another notes that shares have shed more than half their value since the Deepwater Horizon disaster; says the magnitude of loss doesn't appear entirely rational and the day's jump may not be either. Shares now +5.5% at 319p. ([email protected]) 0708 GMT [Dow Jones] Premier Foods (PFD.LN) appoints a new chairman, Ronnie Bell - a former executive of Kraft (KFT) Europe and a until today a non-executive director of Northern Foods (NFDS.LN). However, Shore Capital keeps its sell rating, saying its investment thesis remains intact: Premier Foods is over-leveraged and burdened by pension liabilities with an operating platform that is not performing well. Shares +0.7% at 20p. ([email protected]) 0705 GMT [Dow Jones] HMV's (HMV.LN) profits in its final results are in line with expectations says Arden. Says there's no formal comment on current trading but notes the company admits the World Cup has disrupted footfall, as expected. Says HMV management continues to think if it delivers its strategy, profits will follow along with the share price. But Arden says the stock market is sceptical and Arden is disappointed that HMV does not appear to have a 'plan B' to boost its ailing share price with, for example, a share buy back program. But has faith in the company and so maintains buy recommendation. Shares +3.5% at 59p.
