Such an assessment can only be done in light of a market investigation, while taking into account the quantitative thresholds. In its assessment the Commission should pursue the objectives of preserving and fostering innovation and the quality of digital products and services, the degree to which prices are fair and competitive, and the degree to which quality or choice for business users and for end users is or remains high. Elements can be taken into account that are specific to the undertakings providing core platform services concerned, such as extreme scale or scope economies, very strong network effects, data-driven advantages, an ability to connect many business users with many end users through the multisidedness of those services, lock-in effects, lack of multi-homing, conglomerate corporate structure or vertical integration. In addition, a very high market capitalisation, a very high ratio of equity value over profit or a very high turnover derived from end users of a single core platform service can be used as indicators of the leveraging potential of such undertakings and of the tipping of the market in their favour. Together with market capitalisation, high relative growth rates are examples of dynamic parameters that are particularly relevant to identifying such undertakings providing core platform services for which it is foreseeable that they will become entrenched and durable. The Commission should be able to take a decision by drawing adverse inferences from facts available where the undertaking providing core platform services significantly obstructs the investigation by failing to comply with the investigative measures taken by the Commission.
