After a brief lull, the flow of company results is starting to increase again, with big names such as Admiral, Diageo, Petrofac, G4S, Antofagasta, Cairn, Wood Group, Serco, Tullow, WPP, BHP Billiton and Kazakhmys all set to report.Broker finnCap thinks there is a good chance that Tullow Oil will cut its full-year guidance, after its partner on the Jubilee field, Kosmos Energy, reported a slower than expected ramp-up of production at the field, located off the coast of Ghana."Current guidance is 90-94mboepd [million barrels of oil equivalent per day] and we are forecasting 88.9mboepd, having already anticipated these difficulties," finnCap said.Tullow is now expected to hit full production at its Jubilee field in December, rather than the originally targeted August. Car insurance specialist Admiral should see strong growth in policy sales, Nomura predicts. "Commentary from Aviva, RSA, RBSI [Direct Line and Churchill] and AXA suggested motor rates continuing to increase, and against this backdrop, we expect Admiral to book strong policy growth," Nomura said. "In addition, one of the reasons Admiral had such strong growth in policy count in 2010 (+32%) and 1Q [first quarter] 2011 (c33%) was in part attaining market share from RBSI, and we note RBSI again decreased in force policies in Q2 2011 by 3% vs 1Q 2011. We look for 33% growth in group policy count for 1H [the first half], in line with Q1," the broker added.Monday August 22INTERIMSAmlin, Capital Drilling Ltd.
