What is Stock exchange?
Also known as: exchange, securities exchange
An organised market (a place or an electronic system) where company shares and other securities are bought and sold under set rules. Trading on an exchange usually goes through brokers, and the price is formed where buyers' and sellers' orders meet and is published openly for everyone. The exchange is the centre of the secondary market: investors sell previously issued securities to each other there, and the issuer receives no money from these trades. For a security to be admitted to exchange trading, the issuer must meet the exchange's requirements and keep disclosing information.
