RSA Surges Most in Two Decades as Zurich Weighs Takeover Bid

RSA Insurance Group Plc surged by the most since the deal that created it almost two decades ago after Zurich Insurance Group said it was considering a bid, stirring speculation the British company could attract another suitor.

RSA may fetch about 563 pence a share, or about 5.7 billion pounds ($8.8 billion), according to Panmure Gordon & Co. analysts. The stock jumped 18 percent to 518.5 pence in London, the biggest gain since Sun Alliance Group Plc and Royal Insurance Holdings Plc’s merger in 1996.
