Will Duff Gordon hosted a panel of three short selling academics at the Data Explorers London 麻豆传媒 Financing Forum.
Each academic made their case for short selling by providing a summary of their key findings in their individual research which is available at dataexplorers.com/research.
Dr. Alessandro Beber, Amsterdam Business School compared the performance of markets in countries that impose a short selling ban and those that do not. The costs and benefits of short selling and the effects to single stocks were weighed up. A key finding was the fact that banning short selling has a detrimental effect on liquidity. It was found that the negative effect on liquidity is at approximately 25% in countries with a ban. Liquidity problems are seen to be further amplified in small, volatile or non-option stocks.
Ekkehar Boehmer, EDHEC Business School, used the daily shorting flow in the US markets to carry out their research. Findings showed that short selling accounts for a large proportion of trading activity, 28% in 2008. Dr. Pedro Saffi led with 鈥淒on鈥檛 shoot the short selling messenger鈥�!
The academics were asked to consider a perception that short sellers 鈥渂oost bubbles and then prick the bubble鈥� to profit.
