What Is an Activist Investor?

An activist investor, typically a specialized hedge fund, buys a significant minority stake in a publicly traded company in order to change how it is run.

The activist investor's goals may be as modest as advising company management or as ambitious as forcing the sale of the company, divestitures or restructuring, or replacing the board of directors.

Unlike private equity firms that buy and restructure companies in order to profit when they are resold, activist investors seldom acquire full or majority stakes.1 Instead, they use public communications and private discussions to win over other shareholders and company insiders. When such efforts fail, an activist investor may pursue a proxy contest to elect new directors in order to force the company to meet their demands.

KEY TAKEAWAYS

  • Activist investors buy minority stakes in public companies to change how they are run.
  • If they fail to persuade company managers, they may wage a proxy fight for board seats.
  • Some hedge funds specialize in activist investing while institutional investors may engage in it from time to time.
  • Investor activism may focus on maximizing shareholder value or on the company's social responsibilities.
  • The SEC has proposed tougher disclosure rules for activist investors that critics contend may make activism unprofitable.

Understanding Activist Investors

Activist investors are sometimes called shareholder activists, a term also used to describe those lobbying companies to improve working conditions for the overseas employees of their contractors, or backers of a dissident board slate elected to fight climate change.23

However, many activist investor campaigns seek only to maximize shareholder value, and most of those are the work of hedge funds specializing in the unique mix of public pressure, behind-the-scenes lobbying, and business expertise required.

Unlike the public pension funds and mutual funds that also engage in activism at times, activist hedge funds may hold highly concentrated stakes and supplement them with additional leverage from derivatives like stock options to offset the considerable cost of such campaigns. In contrast with institutional investors that sometimes turn to activism after owning a disappointing investment for years, activist hedge funds typically buy a stake in an underperforming company shortly before calling for change, and hope to profit from the resulting turnaround and price appreciation.4
