Leading shares went into a swoon in the final two hours of the trading session, taking their lead from the US which, after spending a while to analyse the non-farm payrolls data, moved lower. Despite coming off the top in late afternoon Footsie finished the day in positive territory, largely due to the strength of resource stocks. FTSE 250 constituent Dana Petroleum was the day's star performer and was largely responsible for the buoyancy of oil stocks after it confirmed last night it is in talks with a potential bidder, widely reported to be South Korean national oil company KNOC. The talk is of a bid being worth around £1.5bn though Dana said the discussions are very early stage. Tullow, Cairn, BG Group and Premier Oil were all higher in sympathy.Elsewhere in the sector BP has started to seek buyers for assets it deems peripheral to help pay for the clean-up cost of the Gulf of Mexico disaster. First on the block could be BP's 60% stake in Pan American Energy in Argentina, possibly to China National Offshore Oil Corporation (CNOOC). Analysts say BP's stake could be worth £6.5bn, especially if other parties express an interest. Reports today suggested Total, the French giant would have a look at the assets.The Australian government's decision to replace the controversial Resources 'Super Tax' with a more moderate alternative gave a lift to BHP Billiton, Rio Tinto and Xstrata.

The battle for ownership of Chloride looks set to come to an end after the electrical plugs and peripherals maker recommended a 375p per share bid by US giant Emerson.

The US outfit has told Brit Insurance it may be prepared to up its £10 a share bid by 50p, but the underwriter thinks this still undervalues the business.Builders' merchant Travis Perkins has seen a strong rebound in trading since March. The Wickes owner now expects its first half will beat its expectations while dividends will resume again with a 5p interim. Group revenue for the six months ended 30 June was up by 4.7%, with like-for-like sales up 3.4%. Like-for-like turnover in the last two months was 10.3% ahead in Merchanting and in the last 9 weeks 1.6% ahead in Retail.

It has acknowledged that Italian plans to stop oil companies drilling near its coastline may affect the company's key Ombrina Mare project. "Once the decree comes into force, it may apply to permit applications currently pending and may apply to the Company's Ombrina Mare project," admits the London-listed firm. Northern Petroleum is one of the lucky ones as it does not expect Italy's plans to set up a five-mile no-drill zone around its coastline will affect the AIM-listed explorer.
