What happens to the stock when one corporation buys out another?

When one corporation buys out another, the stock of the acquiring company may initially decline due to the costs associated with the acquisition and potential integration challenges. Conversely, the stock of the target company typically rises, often reaching the acquisition price offered by the buyer. Investors may assess the strategic value of the acquisition, influencing stock performance in the long term. Overall, market reactions can vary based on perceived benefits or risks associated with the merger.
