Abstract:     
Using an international Thomson Reuters Datastream database where size coverage is unusually wide and data errors have been reduced to a low level, we show that some speci fication decisions, and especially those related to size, may have a signifi cant impact on asset pricing test results. We also show that, in data with wider coverage with respect to size, the Fama-French factor portfolios need to be adjusted and their number increased. Specifi cally, standard asset pricing models leave pricing errors for the ten percent smallest stocks, and two additional risk factors (i.e. one micro-stock factor and one extreme book-to-market factor) are needed to capture this mispricing. This holds both in US and international data. Further research is needed to measure the separate relevance of the possible economic interpretations and to identify more economic explanations for the additional risks associated with the smallest stocks.
