Abstract: This study identifies systemic break points in a factor pricing model for firms traded on European stock markets around the financial crisis. The aim is to shed light on the systemic risk transfer in explaining average stock returns in the fragmented European exchanges. Our analysis takes advantage of recent development in econometrics and employs models which enable "automatic" detection of factor model break points. We find that Western European exchanges are more closely integrated with American financial markets than Northern European stock exchanges and those in the United Kingdom. However, all exchanges were eventually affected by the systemic shock. The results of this study provide insight into immunisation strategies for portfolios created from European stocks.
