Market traders and investors will get a chance to express their views on proposed new short-selling rules in Europe next month, when the Paris-based Committee of European Securities Regulators holds a public hearing on its planned two-tier disclosure system.

Under the CESR proposals, outlined in July, hedge funds and other short sellers could be obliged to reveal short positions of as little as 0.1 per cent of a company’s outstanding equity to the regulator of the most liquid market for the stock.
