London midday: Steady progress

After a subdued start London made steady progress throughout the morning, with insurers and miners leading the way.

Old Mutual, the Anglo-South African insurer that's overhauling its business following the financial crisis, has received a bid from HSBC for a controlling stake in Nedbank Group, South Africa's fourth largest banking group, as measured by total assets.

Old Mutual is a majority owner of Nedbank, currently worth almost $10bn, with a 52% stake. HSBC is looking to acquire up to 70% of Nedbank's shares through an offer to all Nedbank shareholders.

Old Mutual said it has had preliminary discussions with the South African regulatory authorities about the merits of the transaction, but they'll still have to mull over the details.

Elsewhere in the insurance sector Aviva and Prudential move higher as traders look around for the next candidates for mergers & acquisitions activity.

Bid talk is hitting the share price of South African brewer SABMiller, however. There is talk in the market that the company is interested in buying Fosters, the Australian brewer of the eponymous fizzy yellow alcoholic beverage.

While the market awaits for the dust to clear on the indecisive general election result traders have decided that a coalition government should make it less likely that the controversial mining tax will be introduced. As a result, Rio Tinto and BHP Billiton see some demand for their shares.

Others in the mining sector are also in demand, most notably Fresnillo, Antofagasta and Anglo American but ENRC is a laggard.

Robert Swannell, a former banker, has been confirmed as the new chairman of retailer Marks & Spencer.

Oil and gas services group Petrofac is wanted after it posted a 55% jump in half year earnings and said it expects to deliver like-for-like net profit growth for the full year. Earnings before interest, tax, depreciation and amortisation rose to $321.3m in the six months ended 30 June compared with $207.5m last time.

Panmure Gordon described the results as "a very strong set of numbers with underlying net income of US$206.3 million, compared to our forecast of US$192 million," though it stuck with its sell recommendation for Petrofac, while Charles Stanley has downgraded the shares to "hold" from "accumulate" after their recent good run.

The response to sector peer James Fisher's result was not so enthusiastic. The marine services firm posted a 4% hike in half yearly pre-tax profit after strong profit at its specialist technical unit. The group, which supplies lifting equipment and submarine rescue, also raised its interim dividend by 5%.

Bovis plans to resume dividend payments at end of the year after swinging to a half year profit. However, the housebuilder also remains cautious in its expectations of transaction volumes and sales prices in the short term given the low levels of consumer confidence and the ongoing challenges in the mortgage market. Pre-tax profits came to £3.5m in the six months ended 30 June compared with a loss of £8.6m last time.

A combination of the UK winter freeze, the earthquake in Chile, Windstorm Xynthia and the Deepwater Horizon disaster plus lower investment returns knocked first half income at underwriter Hiscox. The shares moved higher, however, even though management said competition remains fierce despite the increase in major catastrophes.

CSR's fight over alleged patent infringement with US giant Broadcom continues with the US firm filing a motion in California to add additional patents. In a statement, CSR said all the additional patents had already been asserted previously by Broadcom in its International Trade Commission against SiRF before it was taken over by CSR.

Residential property firm Grainger said its recently acquired Sovereign Reversions subsidiary has formed a joint venture with Moorfield Real Estate Fund II. Moorfield is paying Grainger £17.5m for its 50% stake in the joint venture, which is half the price Grainger paid for Sovereign Reversions.

Energy conserving building solutions provider Kingspan has restored interim dividend payments after reporting its first profit growth in three years. The group will pay an interim dividend of 4c per share. Operating profit is up 9% in the six months ended 30 June to EUR33.1m.

Biometrics and surveillance software firm RCG revealed a decline in interim profit and issued a cautiously optimistic outlook for the second half.

Shares in Coms, which provides telephony services such as video and voice conferencing, jumped after it announced the launch of an application that enables users of its internet telephony service to control their account from their iPhone .
