There are few large-cap miners whose shares are as geared to commodity prices as India's Vedanta Resources. Last year's share price performance ? a rise of 327 per cent ? said as much. So, too, did yesterday's third-quarter update. The imminent redemption of a $725 million convertible bond at a 40 per cent discount to the current share price may cause short-term volatility. Even so, at £24.84, or ten times next year's earnings, hold on, says the Times.While Tullow trades on a huge multiple (162.1 times Evolution's forecast full-year earnings) that's only because the company just keeps delivering. The Independent said buy twice last year, and Tullow has rewarded us handsomely. There's enough here to suggest this tiger can be ridden higher still. Keep buying.Nobody in the pub sector will nail their flag to the mast and call the end of the downturn, least of all Rooney Anand, the highly cautious chief executive of Greene King.

The shares, which are down 15pc from their recommendation on August 18, remain a speculative buy, says the Telegraph.There are few bigger in the speciality chemicals sector than Johnson Matthey and size matters in this sector. The Independent says just hold for the moment. Buy on any signs of weakness in the shares.It did not take one of Renishaw's precision measuring devices to gauge the turnaround in yesterday's first-half numbers. At 605p, or 21 times next year's earnings, the shares look stretched ? but not once the likelihood of further upgrades is factored in. Buy on weakness, says the Times.Charles Stanley's shares are rather illiquid, but at 11.9 times forecast full-year earnings with a prospective yield of 3.7 per cent, they trade at a discount to the sector. Prospects look good, so the Independent says buy.Please note: Digital Look provides a round-up of news, tips and information that is impacting share prices and the market.
