    Securities & Commodities Investigations

    Related Lawyers

    The Firm’s Securities & Commodities Investigations lawyers have a deep understanding of markets and complex trading and financial products. They regularly represent clients in investigations and enforcement actions by the SEC, the CFTC, FINRA, the National Futures Association and other federal, state, and non-U.S. regulators and self-regulatory organizations. These matters include those involving alleged accounting and disclosure issues, insider trading, market manipulation, spoofing, the FCPA, and issues relating to digital assets. Clients facing securities and commodities investigations turn to the Firm for its record of obtaining favorable outcomes in high-stakes matters. In recent years, we have successfully played a leading role in handling industry investigations into LIBOR, FX, and other benchmark interest rates, navigated clients through large-scale spoofing investigations, and successfully resolved large-scale FCPA matters.

    The Group has extensive experience guiding companies and their senior executives through multifaceted, enterprise-level crises that demand a combination of rapid reaction and strategic thinking.  The Group’s lawyers—many of whom have held senior positions in government—are positioned to serve clients during challenging times. This breadth of practice—the insights and knowledge developed from the volume and variety of matters the Firm has handled—has made it a one-stop shop for clients.

    “If you have a major issue and the CFTC is coming after you, you want them on your side.”
