Michael W. Stocker

A nationally recognized leader in investor advocacy both inside and outside the courtroom.

Mike Stocker co-chairs Hagens Berman’s securities practice with managing partner, Steve Berman. He joined the firm to fight for the same belief spurring the firm's founding: that the powerful must be subject to the same rules as the powerless.

Leveraging the firm's unparalleled track record in bringing corporate giants to justice, Mike works with Hagen Berman’s securities team to protect the transparency and integrity of the U.S. financial markets.

Mike takes a proactive approach to securities litigation, identifying cases using meticulous investigation backed by experts drawn from law enforcement and accounting.

Through work in print and broadcast media, he ensures his advocacy for investors does not end at the courthouse steps, pressing for protection and reform intended not only to redress past harm but to prevent future violations.
