Internet and telephone service provider TalkTalk Telecom took first place on the risers list, having raised its full year earnings guidance as projected cost savings come in ahead of schedule. With just under two months of its financial year left to run, the company has raised full year earnings per share (EPS) guidance by 6% to a range running from 17.0p to 17.5p.

Dixons Retail, the electrical retailing and services company, was on the up after it said it welcomes today's announcement from the Office of Fair Trading (OFT) regarding extended warranties. The OFT's announcement states that major UK electrical retailers have offered legal undertakings to improve the way the extended warranties market works, thereby ensuring fair competition on the market, which is worth around £1bn a year.

Waste management firm Shanks also rose after reporting that trading for the interim period to 31 January 2012 was in line with company expectations despite, as expected, challenging conditions.

Insurance and reinsurance company Amlin rose on positive estimations that its worst case position resulting from the grounding of the cruise ship Costa Concordia would be less than £10m, net of reinsurance recoveries. The shipwreck has led to market claim estimates of $500m to $1bn for the cost of damage to the vessel and further losses from passenger liability claims, removal of wreck and potential environmental claims, the firm said in a trading update.

Meanwhile, Indonesian coal miner Bumi continued to fall on yesterday's news that Nomura has downgraded its rating for the stock from buy to neutral on the back of corporate governance risk, in light of the announcement that a major shareholder of Bumi wants a boardroom shake-up.
