LONDON: Britain’s top share index advanced on Tuesday towards a recent record high, with shares in ARM Holdings and SKY rising sharply after the companies announced strong profits.

The blue-chip FTSE 100 was up 6.17 points, or 0.1 per cent at 7,058.30 points by 1015 GMT after gaining 0.8 per cent in the previous session.

However, the index pared earlier gains after coming within 0.2 per cent of a record high of 7,119.35 points, hit last week.

Shares in SKY rose 5 per cent, the top gainer in the FTSE 100 index, as solid demand for pay-TV in Britain and an improving picture in Germany and Italy helped it post a 20 per cent jump in nine-month profit.

“Another set of encouraging numbers underlines SKY’s determination to position itself as a major European force within the media sector,” Richard Hunter, head of equities at Hargreaves Lansdown Stockbrokers, said.

ARM Holdings rose 4.4 per cent after the British chip designer whose technology powers Apple’s iPhones said it made an encouraging start to the year, with pretax profit up 24 per cent.

The FTSE 100 index has gained 7.5 per cent this year, but lags other major European indexes including Germany’s DAX and France’s CAC, which are both up more than 20 per cent.

There is substantial uncertainty over the outcome of a May election. Prime Minister David Cameron’s centre-right Conservatives and the centre-left Labour Party are neck and neck in opinion polls, indicating that no single party will win a clear majority.

“More generally, a Conservative-led government would likely be expected to react in a more business- and market-friendly manner in the event of unforeseen challenges ... a leftward shift in government is likely to raise the risk premium on domestically exposed stocks,” Goldman Sachs said in a report.

On the downside, Associated British Foods fell 3.1 per cent, the top decliner in the FTSE 100 index, after reporting a 2 per cent fall in first-half profit, warning that currency effects would hit performance in the current year.

Rio Tinto dropped 2.4 per cent after missing first-quarter analyst forecasts for iron ore shipments due to bad weather and transport delays.
