#AceFinanceReport – Britain:May.09: Investors cheered the emphatic and unexpected victory of the Conservatives by pouring money into the stock market, spurring a rally that resulted in the value of British companies swelling by more than £50bn.
The benchmark FTSE 100 index of leading shares leapt 159.87 points to 7,046.82, a 2.3pc surge of that was its biggest one-day jump since January.
The second-tier FTSE 250, which has much greater exposure to the UK economy than the internationally-focused FTSE 100, climbed 487.97, or 2.8pc, to an all-time high of 17,935.93, recording its best day for three and a half years.
In total, the rally resulted in £51.3bn being added to the value of companies listed in the broader FTSE All-Share index amid relief the uncertainty of a hung parliament had been averted.
Sterling advanced 1.6pc to 72.74p per euro, its biggest daily advance since October 2011. It was boosted by expectations that the Tory majority would provide a stable government. It surged as much as 2pc against the dollar in early morning trade to hit $1.5523, which marked its highest level since February.
The Tory win was also felt in the gilt market, where yields on 10-year government bonds, which move inversely to prices, fell as low as 1.74pc as investors anticipated a continuation of the deficit-reduction policies that were pursued by the coalition.
In the stock market, shares in companies that would have been penalised by a Labour-led government spearheaded the rally. Energy suppliers Centrica and SSE gained after the threat of energy freezes was lifted.
Housebuilder and estate agency stocks, which had been rattled by the prospect of rent controls and the mansion tax, also enjoyed strong rises.
