Shareholder Activist hedge funds are known for using their equity stakes in corporations to pressure corporate management for change and push value-creating agendas. Shareholder activism often manifests itself in proxy battles, independent board nominees, litigation efforts, contentious publicity and negotiations. Beyond "value creating" agendas, some shareholder activists also use their positions to champion social causes, using their equity stakes to influence a corporation's management to address environmental, carbon emissions, free trade and human right concerns. Famous hedge funds that are known for employing shareholder activism include Carl Icahn's Icahn Associates, Bill Ackman's Pershing Square, Mario Gabelli's GAMCO, Ralph Whitworth's Relational Investors, Chris Hohn's The Children's Investment Fund, David Einhorn's Greenlight Capital, and Daniel Loeb's Third Point.
