Summary
A hedge fund defendant facing spoofing charges has mounted an argument that the loss of an expert witness is not fatal to the underlying case structure, according to a Law360 report from May 5, 2026. The filing suggests that the core allegations of market manipulation can survive without reliance on a particular expert's testimony, indicating a strategy to establish the viability of the case on factual and circumstantial grounds.
Cohen Milstein, a securities litigation firm with substantial experience in market manipulation cases, is currently prosecuting multiple spoofing-related securities actions. These include claims against major market makers Canaccord Genuity LLC, Citadel Securities LLC, G1 Execution Services LLC, GTS Securities LLC, Instinet LLC, Lime Trading Corp., Susquehanna International Group LLP, and Virtu Americas LLC for alleged repeated manipulation of company stock through spoofing tactics. Additionally, Cohen Milstein is leading separate litigation against UBS Securities involving similar market manipulation allegations.
Spoofing cases in the securities context typically involve the placement of large orders with the intent to create a false impression of market demand or supply, followed by cancellation before execution. These tactics are designed to move prices in a direction favorable to the spoofer's actual trading position. The litigation framework requires evidence demonstrating intentionality and knowledge of the deceptive nature of the conduct.
The hedge fund's argument regarding expert witness loss reflects broader evidentiary realities in complex securities litigation. Even when expert declarations become unavailable, the underlying documentary evidence—including trading records, communications, algorithmic patterns, and market impact analysis—may provide sufficient basis for plaintiff claims to proceed. This positioning suggests confidence in the factual foundation of spoofing allegations independent of expert testimony alone.
