Wettbewerbsbeschränkungen auf Märkten für börsennotierte Aktien und Aktienderivate

For a long time, markets for listed stocks and listed stock derivatives have been regarded as immune to competition restrictions or distortions. This dissertation disproves this generally accepted theory and shows that numerous anticompetitive practices can and do occur in this segment of financial markets. Its comprehensive analysis includes market cornering, agreements that restrict supply in initial public offerings and instances of coordinated market manipulation. It considers the latest empirical findings relating to capital markets and, since it refers to the point at which antitrust law and capital markets law overlap, also examines the relationship between both legal fields. Using the example of coordinated market manipulation, the author ultimately analyses sanctions and damage claims arising from parallel violations of antitrust law and capital markets law.
