Quantum BioPharma (NASDAQ: QNTM) a déposé un mémoire juridique s'opposant à la requête conjointe de CIBC World Markets et RBC Dominion Securities visant à faire rejeter l'affaire dans le district sud de New York. Le procès allègue que les défendeurs ont pratiqué une manipulation de marché par "spoofing" entre janvier 2020 et août 2024, réclamant des dommages dépassant 700 millions de dollars USD.
L'entreprise affirme que son action se négociait au-dessus de 460 dollars USD par action en janvier 2020, avec une capitalisation boursière proche d'un milliard de dollars, avant d'être artificiellement déprimée. Les cabinets d'avocats Christian Attar et Freedman Normand Friedland LLP gèrent l'affaire sur la base d'honoraires conditionnels, supprimant ainsi toute pression financière significative sur Quantum. La société suggère que d'autres banques pourraient être impliquées, mais s'abstiendra de les nommer tant que des preuves plus concluantes n'auront pas été recueillies.
Quantum BioPharma (NASDAQ: QNTM) hat im Southern District of New York eine rechtliche Stellungnahme eingereicht, in der sie sich gegen den gemeinsamen Antrag von CIBC World Markets und RBC Dominion Securities auf Abweisung der Klage stellt. Die Klage wirft den Beklagten vor, zwischen Januar 2020 und August 2024 Marktmanipulation durch "Spoofing" betrieben zu haben und fordert Schadensersatz in Höhe von über 700 Millionen US-Dollar.
Das Unternehmen gibt an, dass seine Aktie im Januar 2020 über 460 US-Dollar pro Aktie gehandelt wurde und die Marktkapitalisierung fast 1 Milliarde US-Dollar betrug, bevor der Kurs künstlich gedrückt wurde. Die Kanzleien Christian Attar und Freedman Normand Friedland LLP vertreten den Fall auf Erfolgsbasis, wodurch Quantum finanziell entlastet wird. Das Unternehmen deutet an, dass weitere Banken beteiligt sein könnten, wird diese jedoch erst nennen, wenn es schlüssigere Beweise gibt.

Insights
Quantum BioPharma's $700M lawsuit against major banks for alleged stock manipulation represents significant legal battle with uncertain outcome and high-stakes implications.
Quantum BioPharma has escalated its legal battle against CIBC World Markets and RBC Dominion Securities, filing a memorandum opposing the defendants' motion to dismiss in the Southern District of New York. The company alleges these financial institutions engaged in stock price manipulation through "spoofing" - a deceptive trading practice where false orders are placed and quickly canceled to artificially influence prices.
The allegations cover a 4.5-year period from January 2020 to August 2024, during which Quantum claims its stock was manipulated hundreds of times, driving the share price down from over
Several aspects of this case warrant attention. First, the contingency arrangement with law firms Christian Attar and Freedman Normand Friedland means Quantum faces minimal financial exposure from litigation costs. Second, the company has suggested other unnamed financial institutions may be added as defendants as evidence accumulates. Third, the complaint appears to include specific trading data supporting the spoofing allegations, which will be crucial given the historically high evidentiary bar in market manipulation cases.
While Quantum has expressed openness to settlement, the legal path forward remains uncertain. Market manipulation cases typically face significant hurdles regarding proof of intent and causation. The dramatic stock price decline alleged (from a nearly
