ABSTRACT
The swift growth of large institutional shareholders has reshaped today’s capital markets, as a limited set of asset managers now more often controls sizable shareholdings in rival companies within a single sector. Often labelled “common ownership,” this development has sparked a significant but still unsettled discussion within competition law. Even though standard antitrust systems mainly target overt collusion, restrictive arrangements, exploitative behaviour, and consolidation through mergers. Common ownership raises a quieter difficulty by possibly shifting competitive motivations absent any explicit cooperation. The article explores whether this new type of investor concentration represents a separate antitrust issue that Indian competition law can no longer ignore. Using economic research and comparing trends in the United States, the European Union, and the United Kingdom, the paperoffers a critical assessment of both the conceptual basis and the empirical constraints surrounding the common-ownership claim. It contends that the current record does not warrant viewing common ownership as automatically anti-competitive, yet it also fails to justify leaving it wholly unregulated. Instead of imposing sweeping bans or importing overseas regulatory templates, India should craft a careful, evidence-led approach based on proven competitive injury, industry-tailored vulnerabilities, and strict economic evaluation. This path would protect the efficiency gains linked to institutional investing while ensuring that changing ownership patterns do not erode the core aims of competition law.
