Abstract:
Recent work on the price behavior of French common stocks concluded that the evidence is consistent with equity pricing according to the Capital Asset Pricing Model (CAPM). In this paper we re-examine the evidence on the risk-return characteristics of French equity and show that the estimated parameters of the risk-return relationship exhibit strong seasonality. The risk- return relationship is not linear and portfolio size affect equity pricing during January. These results cast some doubt on the validity of the CAPM as a descriptor of French equity returns.
