Portfolio Monitoring Service


Wolf Popper LLP is a highly experienced securities class action litigation firm headquartered in New York City, with offices in Houston, Texas and San Juan, Puerto Rico. Since its founding over seventy years ago, Wolf Popper has been a leader in efforts to protect the interests of defrauded investors, prosecuting thousands of actions under federal and state laws throughout the United States and abroad. The Firm’s efforts have resulted in recoveries of billions of dollars for aggrieved parties.

Reputation for Success

Wolf Popper’s distinguished reputation is well-known and widely respected. The Firm has one of the longest-standing practices in the field of securities class action litigation, with unparalleled expertise. Wolf Popper’s careful factual and legal research and selective prosecution of securities actions has resulted in a significant percentage of its actions being sustained over motions to dismiss, or settled prior to determination of motions to dismiss, particularly under the Private Securities Litigation Reform Act (the “PSLRA”).


The Firm’s long-established role in the securities bar provides its clients with an understanding and insight into federal securities and state fiduciary duty laws that could only be obtained through years of practice in the fields. For example, in approving the settlement in In re TCW/DW North American Government Income Trust Securities Litigation, the District Court commended Wolf Popper for its “highly competent” representation of the Class. TCW/DW is very significant because it was obtained in a complex area of the law where other firms had been unable to obtain any recovery for their clients.

National Representation

Wolf Popper has been frequently praised by Courts throughout the United States for the quality of our representation of clients in securities litigation. The firm has been called “extraordinary” and “highly expert.” More information about the firm can be found in the Securities Litigation section.


Wolf Popper PSC, a satellite office located in San Juan, Puerto Rico, was opened in January 2009. Latin American institutional investors worldwide can expect fully bilingual services in portfolio monitoring and securities litigation from professional and diverse experienced attorneys.
