Areas of focus within litigation.

Securities & Fraud Litigation

We can assemble an effective and efficient team for a variety of situations. Our attorneys handle litigations, securities fraud investigations and non-public proceedings involving securities law, company governance, regulatory inquiries and shareholder/partner disputes.
We are effective advisors in securities fraud claims against companies—and their officers, directors and advisors—that misrepresent information and cause harm to their shareholders. We advise clients on best practices, including the following:


  • Being misled in connection with a stock purchase
  • Being misled in connection with a company’s financial condition
  • Being misled in connection with casting a vote in a proxy solicitation
  • Being a recipient of a fraudulent misrepresentation in a business transaction
  • Churning
  • Unauthorized trading
