The term “stock market” refers to the entire market for shares or “stocks” in a region, country or even globally. The stock market is made up of supply (all shares made available to the public), demand (investors who want to invest in enterprises).
The stock market is not to be confused with a stock exchange. While a stock exchange is a single, physical or electronic platform on which stocks are traded, the stock market is the entire market for shares.
