Herding in French Stock Markets: Empirical Evidence from Equity Mutual Funds [extrait BMI 127]

Version numérique PDF

Using the traditional herding measure of Lakonishok, Shleifer and Vishny (1992) (LSV) and the more recent measure of Frey, Herbst and Walter (2007) (FHW), we assess herding by French equity mutual funds between 1999 and 2005. We show that LSV herding amounts to 6.5%, while FHW herding is approximately 2.5 times stronger. We find that herding is stronger in small-capitalization firms than in medium- and large-capitalization firms. Herding is also more severe among foreign stocks than among EU-15 or French stocks. Moreover, French mutual funds are shown to partially use positive feedback strategies. Finally, we establish that sell-herding has a destabilising impact on stock prices and that this impact is larger for foreign stocks.Keywords: herding, herding measures, mutual funds, fund managers, feedback trading.JEL Classification: G11, G23.
