FTSE 250 movers: LSE advances after winning LCH.Clearnet's hand

The board of the London Stock Exchange (LSE) and the top brass at clearing house LCH.Clearnet have thrashed out the terms under which the clearer will become part of the LSE group, sending the latter's shares soaring. Dairy foods group Dairy Crest was another big riser, after announcing that it is shaking up its French branded spreads business and considering a possible sale of its St Hubert division. Digital sports media group Perform was extending gains made yesterday, after Credit Suisse said earlier this week "we believe that Perform's rights portfolio, digital positioning and resultant top-line growth will likely attract potential acquisition interest." Meanwhile JD Wetherspoon left a bitter taste in shareholders' mouths as the fast-growing pubs group revealed a surprise reverse in like-for-like (LFL) sales for the current year. Total sales in the six weeks to March 4th were up 6.1% on the corresponding period of 2011, but that number is boosted by contributions from pubs recently added to the group's estate. LFL sales over the same period were down 0.6% year-on-year, a sharp turnaround from the preceding six-month period, when LFL sales grew 2.1%.
