NEW YORK, NY - January 7, 2026 (NEWMEDIAWIRE) - Kaplan Fox & Kilsheimer LLP announces that a class action lawsuit has been filed against Canadian Imperial Bank of Commerce (“CIBC”) and Royal Bank of Canada (“RBC”), as well as their broker-dealer subsidiaries (the “Defendants”) on behalf of investors who sold the securities of Quantum Biopharma Ltd., formerly known as FSD Pharma, Inc.

The complaint alleges that “spoofing” is a manipulative and illegal trading practice that involves submitting and then cancelling buy or sell orders without any genuine intent to execute them.
The complaint alleges that during the Class Period, Defendants repeatedly entered thousands of spoofed sell orders designed to create the false impression in the market that Quantum’s stock price was falling and that these manipulative orders were calculated to (and successfully did) deceive or induce other investors to sell their holdings at artificially low prices. Further, the complaint alleges that Defendant’s purchased shares at these artificially depressed levels and positioned themselves to profit at the same time that investors were baited into selling shares at artificially depressed prices.
