Certificates on the stock exchange represent ownership of a certain number of shares in a company. When an investor buys shares of a company, they receive a certificate as proof of ownership. This certificate includes details such as the investor's name, the number of shares owned, and the company's name. Certificates can be physical or electronic, with electronic certificates being more common in modern times. Physical certificates are paper documents that can be used to transfer ownership of shares, while electronic certificates are stored electronically in the investor's brokerage account. When an investor wants to sell their shares, they can transfer ownership by endorsing the physical certificate or electronically transferring the shares through their brokerage account. This process allows for the buying and selling of shares on the stock exchange. **

Ultimately, the interaction between buyers and sellers in the market determines the price at which a stock is traded. **
