FTSE 100 - Winners

Aviva shares, up 2.5%, are the biggest risers on the blue-chip index. The financial services provider announced Wednesday that it had completed the sale of its US operations to Athene Holding Ltd in a deal worth USD2.6 billion, some USD800 million more than previously announced.

J Sainsbury, up 1.2%, and Tesco, up 1%, are big gainers. The food retailers are rebounding from Wednesday's lows after investors reacted negatively to their trading statements. Sainsbury's is benefiting from Nomura increasing its price target to 370 pence from 350p. Similarly, Citigroup upgraded Tesco to Neutral from Sell, raising its price target to 350 from 285. However, Deutsche Bank, JP Morgan and Macquarie have all cut Tesco's price target. Both companies are trading close to pre-announcement levels.

BP climbs 0.9% after the Financial Times reported Thursday that it had reached a milestone in its legal battle to limit its compensation settlement for the 2010 Deepwater Horizon disaster. The FT announced that the oil and gas company had received a favourable ruling from a US court. The court on Wednesday night approved an injunction to stop payments to businesses that had not "experienced actual injury traceable to loss" from the Deepwater Horizon accident, overturning an earlier decision. The ruling may improve BP's chances of preventing the cost of the settlement rising beyond double its original estimate of USD7.8 billion.

FTSE 100 - Losers

Sports Direct International, down 2%. The company announced that Chief Executive Officer Dave Forsey and Group Finance Director Bob Mellors, exercised options granted to them under the company's executive bonus share scheme, by acquiring 1.0 million shares and then each selling 950,000 them at a price of 680.0 pence per share on Wednesday. The 50,000 shares each retained by Forsey and Mellors are their only holdings in sporting good company, representing 0.01% stakes.

William Hill falls 1.5% after the company warned that gross win margins in sports betting were below the year before. In its interim management statement for the 13 weeks ended October 1, the company said its overall quarterly performance was impacted by quiet July trading in Retail together with lower results-linked gross win margins in the quarter. Analysts at Numis remain upbeat, but note that profits have fallen short of expectations by GBP20 million.

Standard Chartered drops 0.9% in the aftermath of Numis downgrading its recommendation. Numis cuts Standard Chartered's recommendation to Hold from Add, decreasing its price target to 1,500 pence from 1,780p. The downgrades are made as Numis reduces its 2013-2014 forecasts for Standard Chartered by 5%. Currency depreciation across a large number of Standard Chartered's operational territories has hit the international banking group hard. Numis estimates that currency alone reduces estimates by 2%. Weak third-quarter financial markets volumes also are to blame.

It now expects revenues in the year to March 31, 2014 to be between GBP275 million and GBP285 million, up from previous guidance of between GBP235 million and GBP245 million, after making progress in integrating the targeted therapies division of Nordion Inc., and EKOS Corporation, deals that it completed in July.

FTSE 250 - Losers

Ophir Energy, down 4%. The oil-and-gas producer said Wednesday that it had successfully completed the Pweza-3 appraisal well and flow test in Block 4, Tanzania. However, the stock falls for a second day as the market has little interest in appraisals until there are further farm-out announcements, says Cannacord analyst Charlie Sharp. A farm-out announcement is an agreement to outsource production of discoveries, rather than simply reporting the discoveries.
