The FTSE 100 was up a fraction in early trading after falling to a three month low at the end of trading on Wednesday.
The index inched up 0.02% to 4,007.94 as of 9:10am, and more sectors were in the black than the red, with capital goods and basic materials leading the way, up 0.81% and 0.78%, respectively.
Companies doing well included defence mammoth BAE Systems and Reed Elsevier, the owner of the LexisNexis database.
The former company was up nearly one per cent, or three points, to 390.00 as of 9am off the back of news the company's full year profits for 2008 were up more than 90% due to increased demand for armament from the Iraq and Afghanistan wars.
Reed Elsevier, meanwhile, also reported strong 2008 profits due to higher sales at its health publishing business and cautious development plans for 2009. The company's stock was up 4.51%, or 23.50 points, to 544.00 in early trading.
Companies pulling the FTSE down included the London Stock Exchange and the Land Securities Group.
The LSE dropped 3.60% to 448.25 off news the number of stocks trading on its junior Alternative Investment Market had fallen lowest level since 2006.
The latter company's stocks was affected after it announced a £763m rights issue, in which it will offer eight shares for five at 270p. The news comes just days after similar property companies British Land and Hammerson plc announced plans to issue £1.3bn in rights. The stock slipped to 2.64% to 553.00.Investment Week
