Although most stocks are traded through a broker , it is important to understand the relationship between exchanges and the companies that trade.
Also, there are various requirements for different exchanges designed to protect investors. A stock exchange is where different financial instruments are traded, including equities , commodities , and bonds. Exchanges bring corporations and governments, together with investors.
Exchanges help provide liquidity in the market, meaning there are enough buyers and sellers so that trades can be processed efficiently without delays. Exchanges also ensure that trading occurs in an orderly and fair manner so important financial information can be transmitted to investors and financial professionals.
Stocks first become available on an exchange after a company conducts its initial public offering IPO. A company sells shares to an initial set of public shareholders in an IPO known as the primary market. After the IPO floats shares into the hands of public shareholders, these shares can be sold and purchased on an exchange or the secondary market.
The general public can trade shares on the secondary market after a company's initial public offering. The exchange tracks the flow of orders for each stock, and it's the flow of supply and demand that establishes a stock's price.

Although this system is slowly being phased out by electronic systems, some exchanges still use the auction system, including the New York Stock Exchange NYSE.
The NYSE Closing Auction is the last event of the trading day when the closing price for each stock is determined by bringing all buyers and sellers together to establish a price for all those involved. The New York Stock Exchange is the world's largest equities exchange. Although some of its functions have been transferred to electronic trading platforms, it remains one of the world's leading auction markets, meaning specialists called "Designated Market Makers" are physically present on its trading floors.

Listed companies are largely regulated and their dealings are monitored by market regulators, like the Securities and Exchange Commission SEC of the U.
