A corporate raid is a strategy used by investors or companies to gain control of a target company, often through the purchase of a significant amount of its shares. This can lead to changes in management, strategy, or ownership. The goal is typically to increase the value of the target company or to sell it for a profit. These raids can be hostile, meaning the target company's management opposes the takeover, or friendly, where both parties agree on the terms. Corporate raids are often associated with activist investors and can significantly impact the stock market and the overall business landscape.
