Activism is a strategy in which an investment manager takes a minority position in a public company and elaborating a course of action that unlocks value in order to transforms the long-term performance of the target company. There are numerous ways which activist shareholders exert influence on the board of directors or company management. Activist investors typically start with simply engaging in dialogue with the company leaders to encourage change. Some activist shareholders also take their concerns public, using the media to illustrate their perspective and expectation. Activists seek to influence a company, rather than control it. They uses a hybrid approach between private equity and hedge fund. I see Activism becoming more sophisticated and spread across Europe. In the coming years, Activism will adopt a more constructive approach by working closely with corporate boards in a cooperative way. Sharing my activist vision, this presentation will detail the understanding shareholder activism.
