After a choppy week for Europe's stocks, four Eurozone countries have resorted to methods, unseen since the 2008 crisis, to try and calm markets.

The practice sees investors selling borrowed stocks that are expected to fall in price, before buying them back and keeping the difference. Short-selling has been blamed for increasing recent market volatility.
