The Undesirable Effects of Banning Short Sales

An in-depth study of the short-selling market calls into question both the reasons for the decision to ban short selling and the prejudices that weigh on those who short. According to recently published data (for the United States in particular), a large majority of short sellers are market makers who are hedging their bets on the options markets. They were not affected by the ban, which means that those who were using options to take synthetic short positions continued to do so. The others involved in short selling are mainly hedge funds.
