Activist Investing is an attempt to take over a company by pressuring its management to make changes or change its entire management outright. As activist investors are fairly new, they are extremely influential in the international capital markets, shareholders at publicly traded companies who attempt to affect change in an organization either by directly appealing to, or putting heavy pressure on, the company’s board of directors, bypassing the normal advisory process. With activist investing, you can buy or sell your stakes without warning, catching small investors by surprise.
