Buy actions, also known as buying stocks or securities, refer to the process of acquiring ownership in a company or an asset. When you buy actions, you essentially purchase a share of ownership in the underlying company. This ownership entitles you to certain rights, including voting rights in corporate matters and a portion of the company's profits in the form of dividends.
