London - Bank shares rallied in early trading on London's stock market Friday as new restrictions on speculative trading came into force.
The Financial Times Index (FTSE-100) was up by more than 6 per cent after the Financial Services Authority banned so-called short-selling, a practice in which traders look to profit from falling share prices.
As markets opened, the FTSE-100 index was up 240.7 points, taking it above the crucial 5000-point mark to 5120.7 points.
The temporary ban, to last until January, came into effect at midnight Thursday.
