News that Euronext, the operator of the Brussels, Amsterdam, Paris and Lisbon bourses, is ready to table a bid for the London Stock Exchange lifted the latter 7p to 572p. Curious, then, that the LSE's fourth-biggest shareholder, Fidelity, has been 'aggressively' reducing its holding, raising fears the Euronext or Deutsche Borse bids may not succeed. Since 25 January, Fidelity has sold 3.76m LSE shares at between 560p and 580p, cutting its holding from 6.75% to some 5%.
