COMMUNICATION FROM THE COMMISSION Commission Notice on the definition of the relevant market for the purposes of Union competition law · European Union
(70) As regards evidence on the evolution of prices over time, many different factors unrelated to demand substitution can cause price co-movements. On the other hand, the absence of price co-movement or the existence of diverging prices typically indicates that products are unlikely to be demand substitutes. Therefore, analyses of price co-movements, including quantitative techniques such as price correlation or stationarity analyses, are in principle more informative when they indicate that two products are not in the same market.
