This paper analyses the consequences of the process of financial and economic integration on European equity markets. It documents significant changes in ?fundamentals?, notably an increased synchronization of macroeconomic activities, and a non-negligible evolution in pricing, with a decrease in the cost of capital and converging equity premiums. As to equity returns themselves, in the face of what could turn out to be long-run upward trends in the correlations among both country and sector returns and a narrowing of the superiority of country factors, the benefits to be gained from finding diversification opportunities at a more disaggregated level appear to be higher than ever.
