Activist investors are individuals or groups that buy significant shares in a company to influence its management and operations. Their goal is often to increase the company's value, which can lead to higher stock prices. They may push for changes such as restructuring, cost-cutting, or even changes in leadership to achieve their objectives. These investors typically engage in campaigns to persuade other shareholders and the company's board to adopt their proposals. Activist investors can include hedge funds, private equity firms, or wealthy individuals, and their actions can lead to both positive changes and controversies within the company, impacting its overall direction and strategy.
