LONDON (MarketWatch) -- Britain's Financial Services Authority on Thursday announced the unprecedented move of banning short-selling and forbidding any increase in new positions. Also, disclosure will be required on all positions of more than 0.25% of a stock. The ban is due to remain in force until Jan. 16, but it will be reviewed in 30 days. "While we still regard short-selling as a legitimate investment technique in normal market conditions, the current extreme circumstances have given rise to disorderly markets. As a result, we have taken this decisive action, after careful consideration, to protect the fundamental integrity and quality of markets and to guard against further instability in the financial sector," said Hecton Sants, chief executive of the FSA.
