Abstract

On September 2008, Consob banned the short-selling of financial stocks in the Italian equity market. We analyse the effect of these bans on liquidity, returns, volatility and market efficiency comparing a sample of 23 financial stocks with a control group. The analysis shows a reduction in liquidity for the banned stocks and no significant differences in returns, volatility and market efficiency between the two groups, testifying the inability of restrictions to achieve the purpose for which they were introduced.
