Key Takeaways

  1. An activist investor is an individual or group that purchases a significant amount of a company’s shares and uses their equity to push for change in the company. This can include changes in management, corporate policies, or the company’s financial structure.
  2. Activist investors aim to increase shareholder value by influencing the company’s decisions, as they often believe that the current management is not maximizing the potential value of the company. They may employ various strategies such as publicly voicing their concerns, submitting shareholder proposals, or attempting to gain board representation.
  3. While activist investing can lead to positive change by holding companies accountable and driving improvements, it can also be seen as disruptive and contentious, as it can lead to power struggles within the company and sometimes cause short-term-focused decisions.


The term “Activist Investor” holds significant importance in the business and finance world as it refers to an individual or entity that acquires a substantial stake in a publicly-traded company with the intention of influencing its management and strategic decisions. By doing so, activist investors often seek to unlock hidden value within a company, advocating for changes like operational improvements, financial restructuring, management overhaul, or even pursuing its sale or merger. Their prominent role in the corporate landscape can lead to increased shareholder value, heightened corporate governance, and improved overall business performance. However, it may also potentially create short-term turbulence in stock prices or hinder long-term growth, depending on the investor’s strategies and goals. Overall, the involvement of activist investors significantly shapes the direction and operation of businesses in the contemporary market.


The primary purpose of an activist investor is to actively influence a company’s management to improve corporate governance, financial performance, or unlock hidden value by strategically utilizing their equity stake. These investors, who may be individuals, hedge funds, or private equity firms, often engage with a company’s board of directors, proposing changes in management decisions or policies, restructurings, stock buybacks, and other such actions that could potentially enhance shareholder value. Activist investors generally come into play when they perceive that a company’s management is not optimally utilizing the company’s resources or applying sound investment strategies, and hence, impeding the company’s growth potential.

Activist investors can play a crucial role in bringing about meaningful changes within an organization and providing long-term benefits to all its stakeholders. In many cases, their engagement can result in improved fiscal management, operational efficiency, and company performance, often leading to higher stock prices, improved market perception, and increased value to shareholders. Contrarily, if their investment thesis is not well-thought-out or fails to bring about effective change, the outcomes could be disruptive and end up harming the company and its shareholders. However, it is important to recognize that activist investors often act as catalysts for much-needed change and can help uncover potential opportunities for growth and value creation in the business.


1. Carl Icahn: One of the most well-known activist investors is billionaire Carl Icahn, who takes substantial positions in public companies and often pushes for changes in their management and strategy. An example of his activism is his involvement in Apple Inc. in 2013. Icahn acquired shares in the company and urged management to return more cash to shareholders through share buybacks and dividends. Eventually, Apple increased its share repurchase program and raised its dividend, which pleased Icahn and other shareholders.

2. Bill Ackman: Another prominent activist investor is Bill Ackman, founder of Pershing Square Capital Management. In 2015, Ackman led a proxy battle at Canadian pharmaceutical firm Valeant (now Bausch Health Companies). He acquired a sizable stake in the company and pushed for changes such as the replacement of the CEO and a strategic shift in the company’s acquisition strategy. Despite some initial success, Valeant’s share price ultimately collapsed due to various scandals and controversies, resulting in significant losses for Ackman’s investment.

3. Nelson Peltz: Nelson Peltz, a founding partner of Trian Fund Management, is another noteworthy activist investor. One of his most significant engagements was with Procter & Gamble (P&G) in 2017. Peltz acquired a significant stake in the company and called for a simplified organizational structure, more focused product lines, and increased cost-cutting. After a lengthy and contentious proxy fight, Peltz secured a seat on P&G’s board of directors, and the company started implementing some of the changes suggested by Peltz. The stock price of P&G eventually rose, reflecting an improvement in the company’s performance.
