An EXTREME EXAMPLE of banning short sales

An extreme example comes from Pakistan where the local SEC responded to a stock slump last month by banning short selling and limiting daily price declines to 1% while allowing them to rise by 10%. The initial reaction was a massive 8.6% one day rally followed by 15 straight days of slumping prices amid extremely low turnover, the worst such period for that market in several years. As rioting investors stormed the Karachi Stock Exchange last week, the rules were rescinded."
