The stock market is a market place where buyers and sellers of stocks come together to trade stocks for cash
We need a stock market to ensure that there is an orderly way to trade. This is a good way to ensure that holders and buyers of shares can go to one place as opposed to multiple places to buy and sell
Primary market – Companies go public for the first time (Eg Cochin Shipyard went public in the primary market). The sale of shares will move the cash to the company
Secondary Market – Where the shares are traded between buyers and sellers and the cash movement does not impact the company
