Answer Details
The buying and selling of shares is a function performed mostly by "stock exchanges." A stock exchange is a marketplace where shares of publicly-traded companies are bought and sold by investors.
When a company wants to raise money, it can issue shares of stock to the public. Investors can then buy these shares, which represent a portion of ownership in the company. Shares can be bought and sold on the stock exchange by individual investors, institutional investors, and other market participants.
The stock exchange provides a platform for buyers and sellers to meet and exchange shares, and it facilitates the process of price discovery, where the market determines the price at which shares will be bought and sold. The stock exchange also provides transparency, as investors can see the current price of a company's shares and the volume of shares traded, among other information.
Overall, stock exchanges play a critical role in the functioning of modern financial markets, as they provide liquidity, transparency, and a platform for companies to raise capital.
