Bans on short selling in times of high uncertainty can lead to adverse herding behaviour, says a new paper from The Centre for International Governance Innovation (CIGI).
In Short-Selling Bans and Institutional Investors’ Herding Behaviour: Evidence from the Global Financial Crisis, authors Martin T. Bohl, Arne C. Klein and Pierre L. Siklos examine bans on selected financial stocks in six countries during the 2008-2009 global financial crisis, which provided a setting to analyze the impact of short-sale restrictions. In particular, the authors focused on short-sale constraints’ effect on institutional investors’ trading behaviour and the possibility of generating herding behaviour.
The authors’ conclusions include:
- short-selling restrictions exhibit either no influence on herding formation or induce adverse herding. This implies a higher dispersion of returns around the market compared to rational asset pricing, which can be interpreted as an increase in uncertainty among stock market investors;
- restricting short sellers causes uncertainty about stock prices, which, in turn, may reduce an investor’s trust in the market consensus resulting in adverse herd behaviour;
- and, short-sale bans may also affect the pricing process via institutional investors’ trading because these investors dominate mature stock markets.
